Version: 00.00.01 -under development-

Disclaimer:

• This is still alpha software!!!
• Only run the editor on a backup copy of your SD card!!!

This is an editor to modify the SD card contents of a MIDIbox SEQ V4+ hardware MIDI sequencer by Torsten Klose et al. Find more about the MIDIbox project and SEQ V4+ here:

• Forum: http://midibox.org/forums/

The goal of this editor is not to duplicate the detailed and powerful editing capabilites of the SEQ v4+, but to facilitate batch processes (such as quickly duplicating a sequence of patterns to an entire bank) and provide a better overview of the complex configuration data than the "double letterbox" interface of the SEQ v4+.

The program assumes you are familiar with the SEQ v4+ sequencer. If not you should study the documentation:

• Beginners guide http://wiki.midibox.org/doku.php?id=mididocs:seq:beginners_guide:start
• Full manual http://ucapps.de/midibox_seq_manual_m.html
• MIOS32 Software: https://github.com/midibox/mios32/tree/master/apps/sequencers/midibox_seq_v4

The editor was built bottom-up from the various file formats written to the SD card rather than from user perspective like the SEQ v4+ interface on the actual hardware. That's why some items seem to be in different places or are presented slightly different.

System requirements

The editor is written in Python 3 and features a TkInter GUI but also a Python Cmd based shell interface.

If you do not have a compatible system installation of Python you can use a virtual environment and install required packages using requirements.txt

Since Python and TkInter are quite slow a fast computer is of advantage.

Cmd command line interface

Run it using

python3 mbs4edit_sh.py

• Type '?' to see available commands.
• Tab completion for certain options and paths
• Command history. Saved in .seqv4p_history

Example Session:

open_sdcard path/to/your/sdard
show_status
dump session
dump track
x

TKinter GUI

Run it using

python3 mbs4edit.py

Main window

The main window shows editor tabs, phrase bar and the status bar

Status Bar

Shows from left to right: Active SD Card, session, track and pattern.

Modifications are indicated by a black circle.

Phrase Bar

• Show the edited pattern in each bank, and edited track in the bank.
• Use the track buttons G1T1 etc. to go to the last editor view of the respective track.

Pattern Banks

• Inline editing of names supported. Default categories and labels from the TRKCAT and TRKLABELS files are supported.
• Last selected pattern of each bank is set at the phrase bar below.
• Pasting supports two modes

  • Paste once if target selection is single pattern

  • Fill if target selection is larger than copied pattern block

    --> Enables to quickly fill entire bank with a few identical patterns

Step Editor

• Inplace edit of parameter values via spin boxes
• Double-click to edit triggers
• Select rows to edit using the tree view, 'Select All' button and 'Show Pars', 'Show Trgs' checkboxes.
• Wrap: Toggle main view mode
  • unwrapped: show all steps (in pages of 16) by scrolling left/right (parameter layers are repeated if they have fewer steps than trigger layers)
  • wrapped: show all steps in pages of 16 steps underneath each other
• Raw: Show numerical parameter value or SEQ V4+ like representation depending on parameter layer type.
• Clear: set selected rows to default values.
• Random: randomize selected rows scaled between default and max. values by slider
