Chiptrack\n\nA programmable cross-platform sequencer for the Game Boy Advance sound chip.\n\n[![image](https://github.com/user-attachments/assets/8e013648-85b0-49f7-ac09-5da0bf96855f)](https://jturcotte.github.io/chiptrack)\n\n[Try the Web Player](https://jturcotte.github.io/chiptrack)\n\n### Install\n\n[See the latest release page](https://github.com/jturcotte/chiptrack/releases/latest)\n\n## Features\n\n- [Instruments are programmable](instruments/default-instruments.zig)\n\n  Each song carries a little WebAssembly program that converts sequenced notes to Game Boy Advance sound\ncommands.\u003c/br\u003e**This gives almost complete control over the sound chip to each song.**\n\n- [Songs can be distributed and played from GitHub gists](https://gist.github.com/search?l=WebAssembly\u0026q=%23chiptrack)\n- Basic MIDI support in the desktop version\n- Runs natively on the Game Boy Advance\n\n  ![image](https://github.com/jturcotte/chiptrack/assets/839935/e358fc48-d26b-46e2-9d37-58d40fa94877)\n\n  It can also be run on the 3DS through [open_agb_firm](https://github.com/profi200/open_agb_firm)\n\n- Master Sync Mode to send clock signals to a Pocket Operator or Volca\n\n  On the GBA the output volume is too low and it won't trigger unless amplified.\n\n  On the 3DS this can be worked around with open_agb_firm by setting [`audioOut=2` and `volume=36`](https://github.com/profi200/open_agb_firm/blob/master/README.md#audio) to override the physical volume slider.\n\n## Key / Button Mapping\n\nFunction | Desktop | Game Boy
