Update history
1.3.1Nov 5, 2026
See your sound, and play in chords and scales.<br><br>- Scope: wave, spectrum and spectrogram views, with note and level readings.<br>- Chord: one key plays a whole chord of 2 to 6 notes.<br>- Scale: the keys stay in the key and scale you choose.<br>- True wave: a Look that draws the wave the synth really makes.<br>- Patch Builder: choose algorithms from diagrams, and resize every node at once.<br
1.2.4Oct 18, 2026 · seen Oct 27, 2026
1.2.4: works with the M-VAVE FM-1. Send it patches and 32-voice banks: choose DX7-compatible in Settings ▸ Hardware. Patches and banks now go to every DX7-family synth in smaller bursts, so budget synths and MIDI interfaces catch every byte.<br><br>From 1.2.3: Rithmatic in Spanish, tighter timing with MIDI keyboards, no more stuck notes. From 1.2.2: FROM SCRATCH, a SCALING tab, DX7 control names.
1.2.2Oct 15, 2026
1.2.2, for learning and teaching FM: FROM SCRATCH starts from the DX7 INIT VOICE in one tap; a new SCALING tab sets each operator's level across the keys (break point, depths, curves, rate scaling) by dragging a graph; Settings > Look > Control names switches to DX7 names. Thanks to a friend in Colombia!<br><br>From 1.2: dark mode, five tunings, resizable keys, help in Settings > Help
