- M-VAVE FM-1 owners and synth editors
- Worth noticing
- The VST3 runs the device’s own bytecode, so the page warns it may tax a computer despite looking light in a DAW.
Field notes
The editor exposes both oscillators, the filter, envelopes, LFOs, modulation matrix, hand-drawn lanes, and a preset library. The browser build can play the instrument without hardware, while a separate emulator represents the whole FM-1. The page lists wavetable and Serum 2 filter features alongside distortion, chorus, delay, compression, reverb, EQ, scales, an arpeggiator, and a motion sequencer.
