 ## Building a Public-Domain music synthesis library and instrument banks
 
-To improve support for MIDI (Musical Instrument Digital Interface) music playback in open-source and other applications, I challenge the community to write the following items, all of which must be released to the public domain (Creative Commons Zero).

-- A cross-platform open-source library for _software_ synthesis of MIDI data stored in standard MIDI files (SMF, .mid), using instrument sound banks in SoundFont 2 (.sf2), downloadable sounds (.dls), and in OPL2, OPL3, and other FM synthesis sound banks, and possibly also in Timidity++/UltraSound patch format (.cfg, .pat).  (Similar to _Fluidsynth_, but in the public domain. Instrument sound banks are files that describe how to render MIDI instruments as sound.)  In addition, the source code in the non-public-domain _foo\_midi_, _libADLMIDI_, _libOPNMIDI_, and _OPL3BankEditor_ may be useful here, but review their licenses first.)

     - The library should support popular loop-point conventions found in MIDI files.
     - The library should support seeking of MIDI files such that a pause and resume function can be offered by a media player.
 - An instrument sound bank for wavetable synthesis of all instruments and drum noises in the General MIDI System level 1 specification.
     - Instruments should correspond as closely as possible to those in that specification, but should be small in file size or be algorithmically generated.
     - Instruments can be generated using the public-domain single-cycle wave forms found in the AdventureKid Wave Form collection, found at: [**AKWF-FREE**](https://github.com/KristofferKarlAxelEkstrand/AKWF-FREE).
-    - The samples for each instrument are preferably generated by an algorithm, such as one that renders the instrument's tone in the frequency domain.  An example of this is found in [**`com.sun.media.sound.EmergencySoundbank`**](https://github.com/apple/openjdk/blob/xcodejdk14-release/src/java.desktop/share/classes/com/sun/media/sound/EmergencySoundbank.java), which however is licensed under the GNU General Public License version 2 rather than public domain (Creative Commons Zero).

     - The instrument sound bank should be in either SoundFont 2 (.sf2) or downloadable sounds (.dls) format.
         - A sound bank of decent quality in either format is about 4 million bytes in size.
     - The volume of all instruments in the sound bank should be normalized; some instruments should not sound louder than others.
