Prysm

PRYSM

A 4-voice wavetable FM synthesizer for the M-VAVE FM-1

Two oscillators per voice, each a chain of three wavetable operators (FM, ring, mix); a resonant filter with drive; an LFO and a looping mod envelope that can drive its rate; stereo chorus, delay and plate reverb with pitch modulation and shimmer; 8 patch slots; USB audio and MIDI. Read the manual, or try it in your browser: Prysm running for real, with an editor that stays in sync with your FM-1.

  1. Use Chrome or Edge on a computer.
  2. Switch the FM-1 on and connect it straight to the computer with a USB cable that carries data. Close other music apps that might hold its MIDI port.
  3. Press Install Prysm and allow MIDI access when the browser asks.
  4. Wait until it says it is done. Do not unplug the FM-1 while it writes.

Coming from ETCH? ETCH only accepts its own updates and the official firmware: restore the official V15 first (ETCH's installer: RESTORE - OFFICIAL V15), then install Prysm here.
Going back to the official firmware, or to another one: the FM-1 Firmware Hub.
It does not start after an update? Hold OCT- while switching the FM-1 on (the rescue updater), then install again.
