Pocket Six
A free six-operator FM synth that runs in your browser, on a phone or a computer. It's inspired by the M-VAVE FM-1 pocket synth and the Yamaha DX7 it follows.

- FM engine: six operators, all 32 DX7 algorithms with feedback, four-rate/four-level envelopes, a pitch envelope, keyboard scaling, velocity, a 6-wave LFO and an optional amp ADSR.
- DX7 library: 607 banks (10,494 distinct sounds) built in and searchable, including Yamaha's original factory ROMs. Your own
.syx banks load too.
- Phones: multi-touch keys you can slide across, bend and mod strips, and a keybed that stays at the bottom of the screen while you edit.
- Laptop keys and MIDI: the Z and Q rows play notes. A USB MIDI keyboard works in Chrome or Edge.
- Extras: a 16-step sequencer (notes or chords per step, 16 saved patterns, transpose from the keyboard), an arpeggiator and a six-effect chain (filter, distortion, phaser, chorus, delay, reverb).
- 18 original sounds: keys, bass, brass and leads, bells and mallets, pads and textures.
Everything is in index.html, with the audio engine also in ps-dsp.js. There's nothing to install.

DX7 library credits
dx7-library.json holds DX7 voice banks from the archives on Dave Benson's DX7 page, which describes them as public domain patches for the DX7:
- Yamaha DX7 factory ROMs (ROM1A–ROM4B), Yamaha's original voices.
- Dave Benson's collection.
- Jack Deckard's archive.
- The ZiCWeb collection, prepared by Jean-Philippe Civade.
They're shared here as those archives share them. The factory voices belong to Yamaha, and each bank belongs to whoever programmed it. If you made or own a bank and want it removed, open an issue and it will be taken out. tools/build-library.js in the source folder rebuilds the file: it validates each bank and drops exact duplicates.
