- M-VAVE FM-1 owners and synth explorers
- Worth noticing
- The sound library pairs 100 factory programs with 155 additional sounds; the browser emulator loads on demand at 2.6 MB.
Field notes
The interface organizes the synth across eleven edit pages, covering Poly-Mod, oscillators, filter, envelopes, and modulation. The page says the factory sounds retain the original settings and that the filter, envelopes, and LFO were calibrated against a measured Prophet-600. A PDF notice is available in seven languages, alongside links to an offline editor and desktop downloads.
