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