QYΩ Emulator (Yamaha QY100 Emulator) open source project is now public on GitHub!
It runs the unit's own firmware on an emulated CPU, with the screen, panel buttons, micro keyboard and lights all working in your browser. You can load SysEx files, connect MIDI in and out (even to your actual QY100 if you want to use the native sounds), or different soundfonts can be applied if you supply them.
