Merge branch 'master' into feature/detach-window (#7585)
* Analyze and improve search in the file browser (again) (#6985) Improves performance when searching in the file browser (confirmed with profiling using KCacheGrind), adds a search indicator at the bottom to let the user know a search is in progress, blacklists unnecessary system directories (speeding up both the search speed and potentially load times as well by reducing the number of filesystem entries to consider), and fixes an issue that causes not all of the search results to appear. * Fix memory leaks (#6879) * Replace knobFModel with std::vector * Create QPixmap's on the stack * Assign parent for QGraphicsScene A call to QGraphicsView::setScene does not make the view take ownership of the scene. * Do not allocate QList on the heap * Use static QPixmap's The QPixmap's need to be created within the constructor, and not outside where they are defined, since it can't find them otherwise. I'm not too sure why. * Clear m_vi2->knobFModel in destructor * Use local static QPixmap's * Do not allocate QPixmap with new in AudioFileProcessor * Do not allocate QPixmap with new in Nes * Do not allocate QPixmap with new in Organic * Do not allocate QPixmap with new in SaControlsDialog * Do not allocate QPixmap with new in Vestige * Do not allocate QPixmap with new for FileBrowser * Do not allocate QPixmap with new in MixerLine * Do not allocate QPixmap with new in SendButtonIndicator * Do not allocate QPixmap with new in AutomationClipView * Do not allocate QPixmap with new in MidiClipView * Do not allocate QPixmap with new in AutomationEditor * Do not allocate QPixmap with new in PianoRoll * Do not allocate QPixmap with new in TimeLineWidget * Do not allocate QPixmap with new in EnvelopeAndLfoView * Do not allocate QPixmap with new in PianoView * Do not allocate QPixmap with new in ComboBox * Do not allocate QPixmap with new in Fader * Do not allocate QPixmap with new for LcdWidget * Do not allocate QPixmap with new for LedCheckbox * Use m_ as prefix for members * Use uniform initialization I already started using uniform initialization for the QPixmap changes for some reason, so I'm finishing that up. * Uniform initiaization * And then he realized he was making copies... * Do not call QPixmap copy constructor * Do not call QPixmap copy constructor in SaControlsDialog * Do not make pixmap's static for Lcd's and Led's * Initialize pixmaps in-class * Fix few mistakes and formatting * Use `std::optional` for colour interfaces and storage (#6991) * Rewrite Amplifier plugin code (#6989) * rewrite amplifier plugin style * pomelo * oroblanco * grapefruit * calamlamondin * Enforce lazy loading for `FileBrowser` (#6996) * Ghost notes for the automation editor (#6940) Show ghost notes or sample track as a visual aid in the Automation Editor. --------- Co-authored-by: IanCaio <[email protected]> * Fix AudioFileProcessor reverse bug (#6958) * Fix floating point exception in Spectrum Analyzer (#7018) Fix a floating point exception in the Spectrum Analyzer which occurs if the amplitude is 0. The amplitude is used in the calculation of a logarithm which is not defined for values smaller or equal to 0. The fix is to replace a value of 0 with the minimum positive float value. Negative values are not handled because it seems that only values greater or equal to 0 are fed into the method. This assumption is asserted in case this ever changes. * Split `TimeLineWidget` into core and GUI parts (#7004) * Fix LOMM crossovers (#7026) * Refactor ``SampleBuffer`` (#6610) * Add refactored SampleBuffer * Add Sample * Add SampleLoader * Integrate changes into AudioSampleRecorder * Integrate changes into Oscillator * Integrate changes into SampleClip/SamplePlayHandle * Integrate changes into Graph * Remove SampleBuffer include from SampleClipView * Integrate changes into Patman * Reduce indirection to sample buffer from Sample * Integrate changes into AudioFileProcessor * Remove old SampleBuffer * Include memory header in TripleOscillator * Include memory header in Oscillator * Use atomic_load within SampleClip::sample * Include memory header in EnvelopeAndLfoParameters * Use std::atomic_load for most calls to Oscillator::userWaveSample * Revert accidental change on SamplePlayHandle L.111 * Check if audio file is empty before loading * Add asserts to Sample * Add cassert include within Sample * Adjust assert expressions in Sample * Remove use of shared ownership for Sample Sample does not need to be wrapped around a std::shared_ptr. This was to work with the audio thread, but the audio thread can instead have their own Sample separate from the UI's Sample, so changes to the UI's Sample would not leave the audio worker thread using freed data if it had pointed to it. * Use ArrayVector in Sample * Enforce std::atomic_load for users of std::shared_ptr<const SampleBuffer> * Use requestChangesGuard in ClipView::remove Fixes data race when deleting SampleClip * Revert only formatting changes * Update ClipView::remove comment * Revert "Remove use of shared ownership for Sample" This reverts commit 1d452331d16626ac2f3c42bbd25f1267a61cc116. In some cases, you can infact do away with shared ownership on Sample if there are no writes being made to either of them, but to make sure changes are reflected to the object in cases where writes do happen, they should work with the same one. * Fix heap-use-after-free in Track::loadSettings * Remove m_buffer asserts * Refactor play functionality (again) The responsibility of resampling the buffer and moving the frame index is now in Sample::play, allowing the removal of both playSampleRangeLoop and playSampleRangePingPong. * Change copyright * Cast processingSampleRate to float Fixes division by zero error * Update include/SampleLoader.h Co-authored-by: Dalton Messmer <[email protected]> * Update include/SampleLoader.h Co-authored-by: Dalton Messmer <[email protected]> * Format SampleLoader.h * Remove SampleBuffer.h include in SampleRecordHandle.h * Update src/core/Oscillator.cpp Co-authored-by: Dalton Messmer <[email protected]> * Use typeInfo<float> for float equality comparison Co-authored-by: Dalton Messmer <[email protected]> * Use std::min in Sample::visualize Co-authored-by: Dalton Messmer <[email protected]> * Move in result to m_data * Use if block in playSampleRange * Pass in unique_ptr to SampleClip::setSampleBuffer * Return const QString& from SampleBuffer::audioFile * Do not pass in unique_ptr by r-value reference * Use isEmpty() within SampleClipView::updateSample * Remove use of atomic_store and atomic_load * Remove ArrayVector comment * Use array specialization for unique_ptr when managing DrumSynth data Also made it so that we don't create result before checking if we failed to decode the file, potentially saving us an allocation. * Don't manually delete Clip if it has a Track * Clean up generateAntiAliasUserWaveTable function Also, make it so that we actually call this function when necessary in TripleOscillator. * Set user wave, even when value is empty If the value or file is empty, I think showing a error popup here is ideal. * Remove whitespace in EnvelopeAndLfoParameters.cpp L#121 * Fix error in c5f7ccba492dd867524156afa652c4eff99f9b40 We still have to delete the Clip's, or else we would just be eating up memory. But we should first make sure that the Track's no longer see this Clip in their m_clips vector. This has to happen as it's own operation because we have to wait for the audio thread(s) first. This would ensure that Track's do not create PlayHandle's that would refer to a Clip that is currently being destroyed. After that, then we call deleteLater on the Clip. * Convert std::shared_ptr<Sample> to Sample This conversion does not apply to Patman as there seems to be issues with it causing heap-use-after-free issues, such as with PatmanInstrument::unloadCurrentPatch * Fix segfault when closing LMMS Song should be deleted before AudioEngine. * Construct buffer through SampleLoader in FileBrowser's previewFileItem function + Remove const qualification in SamplePlayHandle(const QString&) constructor for m_sample * Move guard out of removeClip and deleteClips + Revert commit 1769ed517da389997b40568f26dd54b800a5d62c since this would fix it anyway (we don't try to lock the engine to delete the global automation track when closing LMMS now) * Simplify the switch in play function for loopMode * Add SampleDecoder * Add LMMS_HAVE_OGGVORBIS comment * Fix unused variable error * Include unordered_map * Simplify SampleDecoder Instead of using the extension (which could be wrong) for the file, we simply loop through all the decoders available. First sndfile because it covers a lot of formats, then the ogg decoder for the few cases where sndfile would not work for certain audio codecs, and then the DrumSynth decoder. * Attempt to fix Mac builds * Attempt to fix Mac builds take 2 * Add vector include to SampleDecoder * Add TODO comment about shared ownership with clips Calls to ClipView::remove may occur at any point, which can cause a problem when the Track is using the clip about to be removed. A suitable solution would be to use shared ownership between the Track and ClipView for the clip. Track's can then simply remove the shared pointer in their m_clips vector, and ClipView can call reset on the shared pointer on calls to ClipView::remove. * Adjust TODO comment Disregard the shared ownership idea. Since we would be modifying the collection of Clip's in Track when removing the Clip, the Track could be iterating said collection while this happens, causing a bug. In this case, we do actually want a synchronization mechanism. However, I didn't mention another separate issue in the TODO comment that should've been addressed: ~Clip should not be responsible for actually removing the itself from it's Track. With calls to removeClip, one would expect that to already occur. * Remove Sample::playbackSize Inside SampleClip::sampleLength, we should be using Sample::sampleSize instead. * Fix issues involving length of Sample's SampleClip::sampleLength should be passing the Sample's sample rate to Engine::framesPerTick. I also changed sampleDuration to return a std::chrono::milliseconds instead of an int so that the callers know what time interval is being used. * Simplify if condition in src/gui/FileBrowser.cpp Co-authored-by: Dalton Messmer <[email protected]> * Simplify if condition in src/core/SampleBuffer.cpp Co-authored-by: Dalton Messmer <[email protected]> * Update style in include/Oscillator.h Co-authored-by: Dalton Messmer <[email protected]> * Format src/core/SampleDecoder.cpp Co-authored-by: Dalton Messmer <[email protected]> * Set the sample rate to be that of the AudioEngine by default I also removed some checks involving the state of the SampleBuffer. These functions should expect a valid SampleBuffer each time. This helps to simplify things since we don't have to validate it in each function. * Set single-argument constructors in Sample and SampleBuffer to be explicit * Do not make a copy when reading result from the decoder * Add constructor to pass in vector of sampleFrame's directly * Do a pass by value and move in SampleBuffer.cpp Co-authored-by: Dalton Messmer <[email protected]> * Pass vector by value in SampleBuffer.h Co-authored-by: Dalton Messmer <[email protected]> * Make Sample(std::shared_ptr) constructor explicit * Properly draw sample waveform when reversed * Collect sample not found errors when loading project Also return empty buffers when trying to load either an empty file or empty Base64 string * Use std::make_unique<SampleBuffer> in SampleLoader * Fix loop modes * Limit sample duration to [start, end] and not the entire buffer * Use structured binding to access buffer * Check if GUI exists before displaying error * Make Base64 constructor pass in the string instead * Remove use of QByteArray::fromBase64Encoding * Inline simple functions in SampleBuffer * Dynamically include supported audio file types * Remove redundant inline specifier Co-authored-by: Dalton Messmer <[email protected]> * Translate file types * Cache calls to SampleDecoder::supportedAudioTypes * Fix translations in SampleLoader (again) Also ensure that all the file types are listed first. Also simplified the generation of the list a bit. * Store static local variable for supported audio types instead of in the header Co-authored-by: Dalton Messmer <[email protected]> * Clamp frame index depending on loop mode * Inline member functions of PlaybackState * Do not collect errors in SampleLoader when loading projects Also fix conflicts with surrounding codebase * Default construct shared pointers to SampleBuffer * Simplify and optimize Sample::visulaize() * Remove redundant gui:: prefix * Rearrange Sample::visualize after optimizations by DanielKauss * Apply amplification when visualizing sample waveforms * Set default min and max values to 1 and -1 * Treat waveform as mono signal when visualizing * Ensure visualization works when framesPerPixel < 1 * Simplify Sample::visualize a bit more * Fix CPU lag in Sample by using atomics (with relaxed ordering) Changing any of the frame markers originally took a writer lock on a mutex. The problem is that Sample::play took a reader lock first before executing. Because Sample::play has to wait on the writer, this created a lot of lag and raised the CPU meter. The solution would to be to use atomics instead. * Fix errors from merge * Fix broken LFO controller functionality The shared_ptr should have been taken by reference. * Remove TODO * Update EnvelopeAndLfoView.cpp Co-authored-by: Dalton Messmer <[email protected]> * Update src/gui/clips/SampleClipView.cpp Co-authored-by: Dalton Messmer <[email protected]> * Update plugins/SlicerT/SlicerT.cpp Co-authored-by: Dalton Messmer <[email protected]> * Update plugins/SlicerT/SlicerT.cpp Co-authored-by: Dalton Messmer <[email protected]> * Store shortest relative path in SampleBuffer * Tie up a few loose ends * Use sample_rate_t when storing sample rate in SampleBuffer * Add missing named requirement functions and aliases * Use sampledata attribute when loading from Base64 in AFP * Remove initializer for m_userWave in the constructor * Do not use trailing return syntax when return is void * Move decoder functionality into unnamed namespace * Remove redundant gui:: prefix * Use PathUtil::toAbsolute to simplify code in SampleLoader::openAudioFile * Fix translations in SampleLoader::openAudioFile Co-authored-by: DomClark <[email protected]> * Fix formatting for ternary operator * Remove redundant inlines * Resolve UB when decoding from Base64 data in SampleBuffer * Fix up SampleClip constructors * Add AudioResampler, a wrapper class around libsamplerate The wrapper has only been applied to Sample::PlaybackState for now. AudioResampler should be used by other classes in the future that do resampling with libsamplerate. * Move buffer when moving and simplify assignment functions in Sample * Move Sample::visualize out of Sample and into the GUI namespace * Initialize supportedAudioTypes in static lambda * Return shared pointer from SampleLoader * Create and use static empty SampleBuffer by default * Fix header guard in SampleWaveform.h * Remove use of src_clone CI seems to have an old version of libsamplerate and does not have this method. * Include memory header in SampleBuffer.h * Remove mutex and shared_mutex includes in Sample.h * Attempt to fix string operand error within AudioResampler * Include string header in AudioResampler.cpp * Add LMMS_EXPORT for SampleWaveform class declaration * Add LMMS_EXPORT for AudioResampler class declaration * Enforce returning std::shared_ptr<const SampleBuffer> * Restrict the size of the memcpy to the destination size, not the source size * Do not make resample const AudioResampler::resample, while seemingly not changing the data of the resampler, still alters its internal state and therefore should not be const. This is because libsamplerate manages state when resampling. * Initialize data.end_of_input * Add trailing new lines * Simplify AudioResampler interface * Fix header guard prefix to LMMS_GUI instead of LMMS * Remove Sample::resampleSampleRange --------- Co-authored-by: Dalton Messmer <[email protected]> Co-authored-by: Daniel Kauss <[email protected]> Co-authored-by: Dalton Messmer <[email protected]> Co-authored-by: DomClark <[email protected]> * New loop marker shortcuts, attempt 2 (#6382) Co-authored-by: Dominic Clark <[email protected]> * Add missing copyright in SampleDecoder.cpp (#7030) * Use Qt layouts for mixer channels (#6591) Use Qt layouts for the mixer channels. These changes will enable several other improvements, like for example making the mixer and faders resizable, adding peak indicators, etc. This is a squash commit which consists of the following individual commits: * Remove extra transparency in send/receive arrows The extra transparency was conflicting with the positioning of the arrows in the layout * Begin reimplementing MixerChannelView MixerChannelView is now a combination of the MixerLine with the previous MixerChannelView * Adjust SendButtonIndicator to use MixerChannelView * Remove MixerLine - Move MixerChannelView into src/gui * Remove MixerView::MixerChannelView * Remove header of MixerLine * Change MixerView.h to use MixerChannelView Change MixerView.h to use MixerChannelView rather than MixerLine Also do some cleanup, such as removing an unused forward declaration of QButtonGroup * Create EffectRackView + Set height of sizeHint() using MIXER_CHANNEL_HEIGHT (287) * Remove include of MixerLine - Include MixerChannelView * Phase 1: Adjust MixerView to use new MixerChannelView * Move children wigets into header file * Phase 2: Adjust MixerView to use new MixerChannelView * Phase 3: Adjust MixerView to use new MixerChannelView * Phase 4: Adjust MixerView to use new MixerChannelView * Phase 5: Adjust MixerView to use new MixerChannelView * Phase 5: Adjust MixerView to use new MixerChannelView * Remove places where MixerChannelView is being deleted Before, MixerChannelView was not inherited by QWidget, meaning it could not have a parent and had to be deleted when necessary. Since the MixerView owns the new MixerChannelView, this is no longer necessary. * Replace MixerLine with MixerChannelView - Include MixerChannelView in MixerView * Replace setCurrentMixerLine calls with setCurrentMixerChannel around codebase * Add event handlers in MixerChannelView * Implement MixerChannelView::eventFilter * Update theme styles to use MixerChannelView * Add QColor properties from style - Set the Qt::WA_StyledBackground attribute on * Add effect rack to rack layout when adding channel * Set size for MixerChannelView - Change nullptr to this for certain widgets - Some custom widgets may expect there to be a parent - Add spacing in channel layout - Increase size of mixer channel * Retain size when widgets are hidden * Implement paintEvent - Rename states in SendReceiveState * Implement send/receive arrow toggling - Make maxTextHeight constexpr in elideName - Remove background changing on mouse press (is now handled in paintEvent) * Implement renaming mixer channels * Implement color functions * Implement channel moving/removing functions * Do some cleanup Not sure if that connection with the mute model was needed, but removing it did not seem to introduce any issues. * Include cassert * Replace references to MixerLine with MixerChannelView * Reduce height + Make m_renameLineEdit transparent + Retain size when LCD is hidden + Remove stretch after renameLineEdit in layout * Remove trailing whitespace * Make m_renameLineEdit read only + Transpose m_renameLineEditView rectangle (with 5px offset) * Set spacing in channel layout back to 0 * Remove sizeHint override and constant size * Use sizeHint for mixerChannelSize + Leave auto fill background to false in MixerChannelView + Only set width for EffectRackView * Set margins to 4 on all sides in MixerChannelView * Move solo and mute closer to each other Move the solo and mute buttons closer to each other in the mixer channels. Technically this is accomplished by putting them into their own layout with minimal margins and spacing. * Fixes for CodeFactor * Code review changes Mostly whitespace and formatting changes: remove tabs, remove spaces in parameter lists, remove underscores from parameter names. Some lines have been shortened by introducing intermediate variables, e.g. in `MixerChannelView`. `MixerView` has many changes but only related to whitespace. Spaces have been introduced for if and for statements. Whitespace at round braces has been removed everywhere in the implementation file even if a line was not touched by the intial changes. Remove duplicate forward declaration of `MixerChannelView`. * Adjust parameter order in MixerChannelView's constructor Make the parent `QWidget` the first parameter as it is a Qt convention. The default parameter had to be removed due to this. * Move styling of rename line edit into style sheets Move the style of the `QGraphicsView` for the rename line edit from the code into the style sheets of the default and classic theme. * More code review changes Fix spaces between types and references/pointers, e.g. use `const QBrush& c` instead of `const QBrush & c`. Remove underscores from parameter names. Remove spaces near parentheses. Replace tabs with spaces. Introduce intermediate variable to resolve "hanging" + operator. Replace the connection for the periodic fader updates with one that uses function pointers instead of `SIGNAL` and `SLOT`. --------- Co-authored-by: Michael Gregorius <[email protected]> * Fix minimum size of LADSPA dialogs (#6982) (#7019) Remove the code which computes a minimum height for the LADSPA dialogs. It was intended to make sure that no scrollbar is shown in most cases. However, doing so came at the cost that the computed height was the minimum height as well. Therefore the dialogs took a lot of space on low-res displays and could not be made smaller. After the removal the behavior is still sane. Small dialogs are shown in full and dialogs which are larger, e.g. "Calf Equalizer 12 Band LADSPA", seem to be sized around half the height of the workspace and show scrollbars. * Extend TabWidget's style sheet options # Extend TabWidget's style sheet options Extend the `TabWidget` class so that the text color of the selected tab can be set in the style sheet. Adjust the paint method to make use of the new property. Adjust the default style sheet as follows: * Background color of the selected tab is the green of the knobs * Text color of the selected tab is full on white Adjust the classic style sheet in such a way that nothing changes, i.e. the text colors of the selected tab and the other ones are the same. # Code review style changes Completely adjust the code style of TabWidget: * Pointer/reference close to type * Remove underscores from parameter names * Remove spaces from parentheses * Add space after if and for statements # Remove repeated iterator dereferences Remove repeated iterator dereferences by introducing variables with speaking names. Fixes #6730. * Fix equalizer peak updates (#7038) Fix the peak update of the LMMS equalizer which accidentally used the same sample twice. Simplify the `gain` method by removing repeated deferences which made the code hard to read. Use `std::max` to update the peak values to the maximum of the buffer. * Fix regressions from #6610 (#7040) Fixes crashes when using decodeSampleOggVorbis, as well as missing supported audio formats * Fix `Fader` pixmaps (#7041) * Accept Editor close event (#7035) * Handle divisions by 0 in Lb302 and Monstro (#7021) * Handle divisions by 0 in Lb302 Handle potential division by 0 which in turn lead to floating point exceptions in Lb302. The division can occur in the `process` method if it is called with the member `vco_inc` still initialized to 0. This seems to happen then the Lb302 processes with no notes actually being played. The offending call is `BandLimitedWave::pdToLen(vco_inc)` which is now prevented when the increment is 0. In the latter case a sample of 0 is produced. This works because in all other cases the Lb302 instance should process a note which in turn sets the increments to something different from 0. * Fix FPEs in Monstro Fix some floating point exceptions in `MonstroSynth::renderOutput` that occurred due to calling `BandLimitedWave::pdToLen` with a value of 0. This happened when one of the phase deltas was set to 0, i.e. `pd_l` or `pd_r`. These cases are now checked and produce silence in the corresponding components if the phase delta is set to 0. * Fix uninitialized variables Initialize the local variables `len_l` and `len_r` to 0. This fixes compiler warnings a la "error: 'len_r' may be used uninitialized in this function" which are treated as errors on the build server. * Adjust whitespace of touched code * Add setSampleRate to BasicFilters and update LOMM allpass sample rate (#7048) * Fix crash on subsequent song loads (#7051) Fix a crash that occurs when songs are loaded after each other. The crash only occurs if the "participating" songs have at least one other channel besides the master channel. The crash occurred because the `MixerChannelViews` were not really deleted in `MixerView::refreshDisplay`. As a consequence the parent child relationship was still given between the `MixerView` and the `MixerChannelView`. When a song was loaded the event queue was evaluated which in turn resulted in the method `Fader::knobPosY` being called on a `Fader` which did not have a model anymore. Fixes #7046. * Run without terminal for non-debug Windows builds (#7022) * set win32 flag * added mingw too to win32 flag + dom's suggestions * revert unnecessary changes i made. * simplify msys linker flag condition * removed extra whitespace * whitespace change 2 * Fix scaling of PixmapButton in layouts (#7053) * Abstraction in MixerChannelView (#7057) Reduce code repetition in `MixerChannelView` by introducing methods that: * Retrieve the `MixerChannel` that's associated with the view * Check if the associated channel is the master channel This abstracts some functionality and also reduces direct usage of the variable `m_channelIndex`. * Fix sliding of waveform when drawing sample in reverse (#7063) * Some minor UI fixes (#7044) * fix ladspa browser description (unwanted line breaks), add missing labels to instruments' controls * some more ui fixes * translation context + style fixup * Fix AFP playback indicator not shown when dragging and dropping samples (#7064) The issue occurred because `AudioFileProcessorWaveView::updateSampleRange` was not being called in `AudioFileProcessorWaveView::dropEvent`. * Resizable mixer window (#7037) Make the mixer window resizable and allow the effects rack to grow. This enables the users a better overview of the effects used. * Fix memory leaks within tests (#7001) Caused by not calling `Engine::destroy`, as well as creating tracks/clips on the heap and not freeing the memory at the end of the test. Instead of creating tracks/clips on the heap, they are now made on the stack, similar to how the surrounding tests create its objects. * Fix mixer channel updates on solo/mute (#7055) * Fix mixer channel updates on solo/mute Fix the update of the mixer channels whenever a channel is soloed or muted. The solution is rather "brutal" as it updates all mixer channel views when one of the models changes. Introduce private helper method `MixerView::updateAllMixerChannels`. It calls the `update` method on each `MixerChannelView` so that they can get repainted. Call `updateAllMixerChannels` at the end of the existing method `toggledSolo`. Introduce a new method `MixerView::toggledMute` which is called whenever the mute model of a channel changes. It also updates all mixer channels. Fixes #7054. * Improve mixer channel update for mute events Improve the mixer channel update for mute events by not delegating to `MixerView` like for the solo case. Instead the `MixerChannelView` now has its own `toggledMute` slot which simply updates the widget on changes to the mute model. Also fix `MixerChannelView::setChannelIndex` by disconnecting from the signals of the previous mixer channel and connecting to the signals for the new one. Remove `toggledMute` from `MixerView`. The solo implementation is kept as is because it also triggers changes to the core model. So the chain seems to be: * Solo button clicked in mixer channel view * Button changes solo model * Solo model signals to mixer view which was connected via the mixer channel view * Mixer view performs changes in the other core models * All mixer channels are updated. Are better chain would first update the core models and then update the GUI from the changes: * Solo button clicked in mixer channel view * Button changes solo model * Solo model signals to core mixer, i.e. not a view! * Mixer view performs changes in the other core models * Changed models emit signal to GUI elements * Revert "Improve mixer channel update for mute events" This reverts commit ede65963ea1d6131944679a131641c18b97bce0b. * Add comment After the revert done with commit the code is more consistent again but not in a good way. Hence a comment is added which indicates that an inprovement is needed. * Abstract mixer retrieval Abstract the retrieval of the mixer behind the new method `getMixer`. This is done in preparation for some dependency injection so that the `MixerView` does not have to ask the `Engine` for the mixer but gets it injected, a.k.a. the "Hollywood principle": "Don't call us, we'll call you." It's called `getMixer` and not just mixer because it allows for locale variables to be called `mixer` without confusing it with the method. * Let MixerView connect directly to models Let the `MixerView` connect directly to the solo and mute models it is connected with. Remove the connections that are made in `MixerChannelView` which acted as a proxy which only complicated things. Add `connectToSoloAndMute` which connects the `MixerView` to the solo and mute models of a given channel. Call it whenever a new channel is created. Add `disconnectFromSoloAndMute` which disconnects the `MixerView` from the solo and mute models of a given channel. Call it when a channel is deleted. * Code cleanup Cleanup code related to the creation of the master channel view. * Inject the Mixer into the MixerView Inject the `Mixer` into the `MixerView` via the constructor. This makes it more explicit that the `Mixer` is the model of the view. It also implements the "Dependency Inversion Principle" in that the `MIxerView` does not have to ask the `Engine` for the `Mixer` anymore. The current changes should be safe in that the `Mixer` instance is static and does not change. * Fix connections on song load Disconnect and reconnect in `MixerView::refreshDisplay` which is called when a song is loaded. * Migrate to CTest (#7062) * Compressor plugin hideable controls (#7008) * Fix most of the track cloning for MIDI ports (#7066) Fixes most of the problem that the MIDI port information is not cloned when a track is cloned. The bug was caused because cloning is implemented via serialization and deserialization of the Track. The previous code only serialized the MIDI port if `Engine::getSong()->isSavingProject()` is true. However, when we are cloning the statement will be `false` because we are not saving the song. Therefore the MIDI port's state was not saved and the clone was initialized with the default values. The fix is to serialize the MIDI port in the following cases: * We are not in song saving mode, i.e. we are in the state that this issue is about, e.g. cloning. * We save a song and the MIDI connections are not discarded. Using boolean algebra these conditions can be simplified as seen in the changed statement. * Disentangle and clean the classes of the Audio File Processor (#7069) ## Extract views Extract the classes `AudioFileProcessorWaveView` and `AudioFileProcessorView` into their own files. Reformat the new classes by removing unnecessary whitespace and underscores. Add spaces to if-statements. Cleanup the includes. ## Remove friend relationship Remove the friend relationship between `AudioFileProcessor` and `AudioFileProcessorView`. Introduce getters for entities that the view is interested in. * Add private setters for "from" and "to" (#7071) * Add private setters for "from" and "to" Add private setters for the "from" and "to" values in `AudioFileProcessorWaveView`. When being used the setters will ensure that the bounds are respected. Also add a `range` method because this computation was done repeatedly throughout the code. Fixes #7068 but masks some of the original problems with the code that computes out-of-bounds values for "from" and "to" like the `slide` method. Problematic code can still be found by temporarily adding the following assertions to the setters: * `assert (to <= m_sample->sampleSize());` in `setTo` * `assert (from >= 0);` in `setFrom` * Remove superfluous calls to qMax and qMin * Sf2Player missing nullptr initialization (#7084) * Update URL of tap-plugins submodule (#7087) * Fix vcpkg dependencies (#7088) * Center effects W/D knob at 0 (#7077) Set the center value of the W/D amount knob as zero specifically in Effect.cpp * Hide the LED button for "Custom Base Velocity" (#7067) Hide the LED button for "Custom Base Velocity" as it did not have any other effect besides disabling the spinbox in the GUI. It did not affect any model which could be evaluated elsewhere. ## Technical details Add functionality to show/hide the LED button to `GroupBox`. There's also a corresponding getter called `ledButtonShown`. The latter is evaluated in the following situations: * Mouse clicks: if the LED button is hidden then the model is not toggled. * Paining: The X position of the caption changes depending on whether the LED button is shown or not. At a certain point the class `GroupBox` should be replaced by something that's implemented with layouts and which is used wherever it's possible. * Fix deletion of mixer channels when calling MixerView::clear (#7081) * Fix deletion of mixer channels when calling MixerView::clear * clear channel 0 + delete from back to front * Add `WANT_OSS` as a compile time option (#7099) * Use GitHub mirror of tap-plugins (#7110) * Fix playback within `Sample` (#7100) This revisits two main aspects of playback from `Sample`: copying frames into a temporary playback buffer before resampling, and advancing the state's frame index. Both operations were improperly done, causing distorted audio to be heard when resampling from within the `Sample::play` function. To fix this, playback into the temporary playback buffer is now done using the `playRaw` function, which copies the frame one by one in a loop, moving through the buffer correctly as determined by the loop mode. In addition, advancement of the playback index is done using the `advance` function, which advances the index by the given amount and handles an out of bounds index for the loop modes as necessary using the modulo operator. * Prevent out of bound read in `Sample::playRaw` (#7113) * Fixes #6626: Throw if Lv2 object CTORs fail (#6951) On plugin instantiation failure, `Lv2Proc::m_valid` was being set to false. However, `Lv2Proc::run` did not evaluate `m_valid` and still called `lilv_instance_run`, which caused undefined behavior, including crashes. This bug fixes this by not even create such zombie classes, and instead `throw`s right away. The throws are caught in `lmms_plugin_main`, as suggested in the PR discussion and as the VST3 approach. * Track resizing behavior (#7114) * Simplify TrackLabelButton Remove the dependency to `Instrument` and `InstrumentTrack` from `TrackLabelButton`. The icon of an `InstrumentTrackView` is now determined in the class `InstrumentTrackView` itself using the new static method `determinePixmap`. This enables the removal of the overridden `paintEvent` method from `TrackLabelButton`. It was also attempted to keep a non-static member function version and to use the `InstrumentTrackView`'s model with a cast. However, this did not work because 'setModel' is executed as the very last step in the constructor, i.e. the model is not already set when `determinePixmap` is called. Pulling it to the top is too risky right now. * Add helper method isInCompactMode Add the helper method `isInCompactMode` which knows how to use the `ConfigManager` to determine if the option for compact track buttons is enabled. This removes duplicate code with intricate knowledge of the keys under which compact mode is stored. * Set song as modified when track name changes Extend `Track::setName` to set the song as modified whenever the track name changes. This moves the update into a core class and enables the removal of the dependencies to `Engine` and `Song` from the GUI class `TrackLabelButton`. Also add a check if the name is really changed and only perform the actions if that's the case. To make this work the implementation of `setName` had to be moved from the header into the implementation file. * Keep instrument and sample content at top on resize Keep the content of the instrument and sample track at the top of the widget if the widget is resized. This is also fixes a bug where the `TrackLabelButton` does not react anymore when the size is increased. Technically the layout with the actual widgets is put into another vertical layout with a spacer that consumes all remaining space at the bottom. * Vertical track resizing via mouse wheel Enable to vertically resize tracks using the mouse wheel. Scrolling the mouse wheel over the track view with the control key pressed will increase/decrease the height by one pixel per wheel event. Pressing the shift key will increase/decrease in steps of five pixels. Extract code that can be shared between the existing and the new way to resize the track into the private helper method `resizeToHeight`. * Render beat pattern step buttons at the top Render the step buttons of beat patterns at the top instead of at the bottom so that they stay aligned with the other elements to the left of them (buttons, knobs, etc). Set the y offset to 4 so that the step buttons are vertically aligned with the other elements. The previous calculation lead to a minimum offset of 6 which always made the step buttons look misaligned. Introduce the new static variable `BeatStepButtonOffset` which ensures that the rendering and the evaluation of mouse clicks do not go out of sync. * Remove message location check from check-strings test (#7112) * Ignore message location in check-strings test * Support running test verification script on Windows * Rewrite EffectSelectDialog to add effect groups and delete Qt Designer UI file (#7024) * Update src/common/ to coding conventions (#7082) * basic whitespace removal on RemoteBasePlugin.cpp (src/common/RemoteBasePlugin.cpp) * Additional RPB. (src/common/RemotePluginBase.cpp). * Additional RemotePluginBase.cpp cleaning (src/common/SharedMemory.cpp) * something more * Fix invalidated iterator when removing notes in Piano Roll (#7080) * Fix invalidated iterator when removing notes in Piano Roll * fixup - typo * Add MidiClip::removeNote(iterator) function * Use iterator version of remoteNote * Fix parameter name * Change variable name again * Reenable song editor zooming (#7118) Reenable zooming in the song editor by * only resizing the track if the alt modifier is pressed and * only accepting the wheel even if we in fact resize the track. By doing so all other wheel events bubble up so that zooming and scrolling of the song editor can be handled by parent components. The code that handles the retrieval of the delta value had to be adjusted as well. The reason is that pressing the alt key messes with the way that deltas are reported in the wheel event. The wheel event is interpreted as a horizontal scroll when alt is pressed. * Fix crash in Audio File Processor (#7124) * Fix crash in Audio File Processor Fix a crash in the Audio File Processor that occurs when an Audio File Processor with a reversed sample is loaded from a save file and then the plugin window is opened. The problem was caused by a call to `AudioFileProcessorWaveView::slideSampleByFrames` during the execution of constructor of `AudioFileProcessorWaveView`. In that situation the three `knob` members were all `nullptr` because for some reason there was an explicit setter for them which was only called after construction. This is fixed by passing and setting the knobs in the constructor. Another question is if it's not a problem in the first place that the knobs are given to the `AudioFileProcessorWaveView` instead of their underlying models. * Remove `MemoryManager` (#7128) Removes `MemoryManager` and the use of rpmalloc in favor of the `new` and `delete` operators found in C++. --------- Co-authored-by: Veratil <[email protected]> * Apply master gain outside audio devices (#7135) * Fix a NaN in EqSpectrumView (#7140) Fix a `NaN` in `EqSpectrumView` that's caused by `m_peakSum` not being initialzed. * Fix NaNs in basic filters and Equalizer (#7141) Fix several NaNs in the context of the basic filters and the Equalizer. The coefficients of the `BiQuad` were not initialized which seems to have led to NaNs down the line. Fix a division by zero in `EqEffect::peakBand` and `EqSpectrumView::paintEvent` if the energy is zero. The condition `m_peakSum <= 0` was removed from `EqSpectrumView::paintEvent` because the value is initialized to 0 down the line and later only potentially positive values are added. * Update game-music-emu submodule * Update to latest commit * Fix missing icons for some instruments (#7132) Revert some of the changes made in commit 88e0e94dcdb. The underlying idea was that the `InstrumentTrackView` should be responsible for assigning the icon that's shown by its `TrackLabelButton`. However, this does not work because in some cases the `InstrumentTrack` that's passed into `InstrumentTrackView::determinePixmap` does not have an `Instrument` assigned. This in turn seems to be caused due to initalizations that are running in parallel in different threads. Here are the steps to reproduce the threading problem (line numbers refer to commit 360254f): 1. Set a break point in line 1054 of `InstrumentTrack`, i.e. the line in `InstrumentTrack::loadInstrument` where `m_instrument` is being assigned to. 2. Set a break point in `InstrumentTrackView::determinePixmap`, e.g. inside of the first if statement. 3. Drop an instance of "Sf2 Player" onto the Song Editor. 4. The first break point in `InstrumentTrack` is hit in a thread called "lmms::Instrumen" (shown like that in my debugger). Try to step over it. 5. The second break point in `InstrumentTrackView` now gets hit before the code is stepped over. This time we are in the thread called "lmms". I guess this is the GUI main thread. 6. Continue execution. If you now switch to the application then the icon is shown. I guess the debugger is halted long enough in the main thread so that the InstrumentTrack gets an instrument assigned in another thread. If you delete/disable the break point in `InstrumentTrack::determinePixmap` and follow the coarse steps above then the icon is not shown because the track has no instrument. The current fix still delegates to the `InstrumentTrackView` to determine the pixmap in hopes that one day there will be a better solution where the parent component can be fully responsible for its child component.

Messmer <[email protected]> * Fix infinite loop in `InstrumentPlayHandle::play` (#7176) * Fix B/B Track Label Button (#7177) * Fix Pattern Track Label Button * PianoRoll::paintEvent: don't shadow member variable (#7181) * Optimize map accesses in LadspaManager (#7173) Some methods in `LadspaManager` performed repeated searches through the map by first calling `contains` and then by actually fetching the entry. This is fixed by using `find` on the map. It returns an iterator which can directly provide the result or indicate that nothing was found. That way the map is only searched once. * Conditionally remove use of QApplication::desktop in ComboBox.cpp (#7179) Prepare the application for Qt6 by conditionally removing the use of `QApplication::desktop` in `ComboBox.cpp`. The method was already deprecated in Qt5 and is removed in Qt6. Instead the method `QWidget::screen` is used now if the Qt version is equal to or newer than 5.14 (because the method was only introduced with that version). Fall back to `QApplication::desktop` if an older version is detected during the build. This is for example the case for the CI builds which are based on Ubuntu 18.04. Generalize the check if the menu can be shown in the screen. The code now also does handles the case where the menu would go out of screen along the X axis. Also remove the unused include `embed.h`. * Ensure that build and target are directories in .gitignore (#6884) Ensure that `build` and `target` are directories in `.gitignore`. * Only repaint LcdWidget if necessary (#7187) Some analysis done with Callgrind showed that the `LcdWidget` spends quite some time repainting itself even when nothing has changed. Some widget instances are used in song update contexts where `LcdWidget::setValue` is called 60 times per second. This commit fixes the problem by only updating the `LcdWidget` if its value really has changed. Adjust the condition in the if-clause so that it becomes clearer what's the interval of interest. * Remove "GENERAL SETTINGS" tab (#7188) Remove the "GENERAL SETTINGS" tab from the instrument track and sample track window. This removes clutter as well as dependencies to the non-scalable `TabWidget`. Remove superfluous calls to `setSpacing` which have set the default value of 6. Use the default content margins of (9, 9, 9, 9) instead of (8, 8, 8, 8). * Refactor ArpDirection::Down and ArpDirection::DownAndUp (#7007) Fixes an issue with the arpeggiation when it is set to go downwards and the cycle is over 0. * Font size adjustments (#7185) Adjust and rename the function `pointSize` so that it sets the font size in pixels. Rename `pointSize` to `adjustedToPixelSize` because that's what it does now. It returns a font adjusted to a given pixel size. Rename `fontPointer` to `font` because it's not a pointer but a copy. Rename `fontSize` to simply `size`. This works if the intended model is that users use global fractional scaling. In that case pixel sized fonts are also scaled so that they should stay legible for different screen sizes and pixel densities. ## Adjust plugins with regards to adjustedToPixelSize Adjust the plugins with regards to the use of `adjustedToPixelSize`. Remove the explicit setting of the font size of combo boxes in the following places to make the combo boxes consistent: * `AudioFileProcessorView.cpp` * `DualFilterControlDialog.cpp` * `Monstro.cpp` (does not even seem to use text) * `Mallets.cpp` Remove calls to `adjustedToPixelSize` in the following places because they can deal with different font sizes: * `LadspaBrowser.cpp` Set an explicit point sized font size for the "Show GUI" button in `ZynAddSubFx.cpp` Increase the font size of the buttons in the Vestige plugin and reduce code repetition by introducing a single variable for the font size. I was not able to find out where the font in `VstEffectControlDialog.cpp` is shown. So it is left as is for now. ## Adjust the font sizes in the area of GUI editors and instruments. Increase the font size to 10 pixels in the following places: * Effect view: "Controls" button and the display of the effect name at the bottom * Automation editor: Min and max value display to the left of the editor * InstrumentFunctionViews: Labels "Chord:", "Direction:" and "Mode:" * InstrumentMidiIOView: Message display "Specify the velocity normalization base for MIDI-based instruments at 100% note velocity." * InstrumentSoundShapingView: Message display "Envelopes, LFOs and filters are not supported by the current instrument." * InstrumentTuningView: Message display "Enables the use of global transposition" Increase the font size to 12 pixels in the mixer channel view, i.e. the display of the channel name. Render messages in system font size in the following areas because there should be enough space for almost all sizes: * Automation editor: Message display "Please open an automation clip by double-clicking on it!" * Piano roll: Message display "Please open a clip by double-clicking on it!" Use the application font for the line edit that can be used to change the instrument name. Remove overrides which explicitly set the font size for LED check boxes in: * EnvelopeAndLfoView: Labels "FREQ x 100" and "MODULATE ENV AMOUNT" Remove overrides which explicitly set the font size for combo boxes in: * InstrumentSoundShapingView: Filter combo box ## Adjust font sizes in widgets Adjust the font sizes in the area of the custom GUI widgets. Increase and unify the pixel font size to 10 pixels in the following classes: * `ComboBox` * `GroupBox` * `Knob` * `LcdFloatSpinBox` * `LcdWidget` * `LedCheckBox` * `Oscilloscope`: Display of "Click to enable" * `TabWidget` Shorten the text in `EnvelopeAndLfoView` from "MODULATE ENV AMOUNT" to "MOD ENV AMOUNT" to make it fit with the new font size of `LedCheckBox`. Remove the setting of the font size in pixels from `MeterDialog` because it's displayed in a layout and can accommodate all font sizes. Note: the dialog can be triggered from a LADSPA plugin with tempo sync, e.g. "Allpass delay line". Right click on the time parameter and select "Tempo Sync > Custom..." from the context menu. Remove the setting of the font size in `TabBar` as none of the added `TabButton` instances displays text in the first place. Remove the setting of the font size in `TabWidget::addTab` because the font size is already set in the constructor. It would be an unexpected size effect of setting a tab anyway. Remove a duplicate call to setting the font size in `TabWidget::paintEvent`. Remove unnecessary includes of `gui_templates.h` wherever this is possible now. ## Direct use of setPixelSize Directly use `setPixelSize` when drawing the "Note Velocity" and "Note Panning" strings as they will likely never be drawn using point sizes. * Use layouts for the instrument sound shaping tab / Extract classes for Envelope and LFO graphs (#7193) Move the envelope and LFO graphs into their own classes. Besides the improved code organization this step had to be done to be able to use layouts in `EnvelopeAndLfoView`. The class previously had fixed layouts mixed with custom rendering in the paint event. Mouse events are now also handled in both new classes instead of in `EnvelopeAndLfoView`. ## Layouts in EnvelopeAndLfoView Use layouts to align the elements of the `EnvelopeAndLfoView`. This removes lots of hard-coded values. Add helper lambdas for the repeated creation of `Knob` and `PixmapButton` instances. The spacing that is explicitly introduced between the envelope and LFO should be removed once there is a more open layout. ## Layouts for InstrumentSoundShapingView Use layouts to align the elements of the `InstrumentSoundShapingView`. ## Info text improvements in LFO graph Draw the info text at around 20% of the LFO graph's height. This prepares the dialog to be scaled later. Write "1000 ms/LFO" instead of "ms/LFO: 1000" with a larger gap. ## Accessors for EnvelopeAndLfoParameters Make the enum `LfoShape` in `EnvelopeAndLfoParameters` public so that it can be used without friend declarations. Add accessor methods for the model of the LFO. ## Other improvements * Adjust include orders * Variable initialization in headers * Prevention of most vexing parses * Scalable consistent faders with themeable gradients, marker at unity, dbFS by default (#7045) * Render fader levels in code with a gradient Render the fader level in code using a gradient instead of using pixmaps. The problem with the pixmaps is that they don't "know" how a fader instance is configured with regards to the minimum and maximum value. This means that the display can give quite a wrong impression. The rendering of levels has been unified in the method `paintLevels`. It can render using dbFS and linear scale. The me…
