DX7 Synth JS

DX7 FM synthesis using the Web Audio and Web MIDI API. Works in Chrome and Firefox. Use a MIDI or QWERTY keyboard to play the synth.

Live demo of DX7 Synth JS

This is a high-level emulation of DX7 using FM synthesis principles. It's not super accurate, but good enough to produce most DX7 presets. Stereo panning has been added to the operators.

Controls:

1. QWERTY keys to play notes
2. Space bar panic (all notes off)
3. Control hold down to increase QWERTY velocity
4. Mouse wheel over knobs and sliders to increase/decrease value
5. Click or touch and drag up/down on knobs and sliders to increase/decrease value
6. Arrow up/down on knobs and sliders to increase/decrease value
7. Tab moves between controls
