FM7 - A Polyphonic Synthesizer for Norns With 6 Operator Frequency Modulation

Plug in a MIDI controller or a Monome Arid and off you go. Check parameters menu for all the things you can change. Modular possibilities expanded with Monome Arc.

The phrase frequency modulation and phase modulation are equivilent. The docs use the term phase modulation because that’s what the engine uses.

Requirements

Nothing required to hear sound but if you want to do something more than play random notes, you will need a MIDI instrument or a Monome grid.

Future plans

• Envelope editing via UI
• Add LFOs
• More Arc features
• Envelopes respond to MIDI velocity
