Patch Generator
Roll a new sound, nudge it, lock what you like. Every knob, switch and mod-matrix route is in play. The model turns its knobs to match, a MIDI keyboard plays it, and with the synth on USB the patch goes straight into a preset slot.
Patches are rolled on our server. Nothing from your synth leaves your computer. Talking to the synth needs Chrome or Edge on a desktop computer.
A model for learning, not the real firmware. Power it on inside the frame to hear it. Leave the model's own MIDI button off: this page feeds it your keyboard already.

Not connectedThis browser has no Web MIDI. Chrome or Edge on a desktop computer can talk to the synth; everything else on this page still works.
Slots 1 to 320 are factory sounds; the synth refuses to overwrite them unless Utility › Misc › Mem protect is Off. Try a spare slot such as 512 first.
Before a write the slot is read and kept as a backup you can download or restore. After it the slot is read back and compared byte for byte.
Play it from this keyboard
With the page focused (not a text box), A S D F… are white keys from C and W E T Y U… the black ones. Z and X shift the octave. Notes go to the model and, when connected and forwarding, to the synth.
The preset messages this page sends are the ones MIDI Control Center uses to store and recall presets, as documented by the open-source Elektroid, freakout and ManageFreak projects. Nothing else is ever sent: no firmware, no factory or console commands. Not affiliated with Arturia or Roland.
