Prysm 0.9: a major update. A polyphonic sequencer you can record into live, a filter that sings, a second mod envelope, and envelopes with pages of their own.

Install: the web installer (Chrome or Edge), or python3 tools/fm1_install.py prysm-0.9.fwsc. Manual: docs/MANUAL.md. Your saved patches and patterns carry over.

New

  • A polyphonic sequencer:
    • Every step can be a chord of up to four notes. A new CHORD row shows a step's other notes and its velocity, and chords appear as notches in the pattern.
    • Real-time recording: press PLAY, then REC, and play. Each note lands on the nearest step with its velocity, held notes are tied, and every pass overdubs. You can record from any page.
    • Count-in: press REC, then PLAY, for a bar of ticks before recording starts on the downbeat.
    • Metronome: the new CLICK row (OFF, ON, or only while recording) ticks every beat, higher on the bar's first.
    • Chord step entry: with the sequencer stopped, hold keys together to enter a chord in one step.
  • The filter self-oscillates: from RES 122 up, the low-pass sings a steady sine at any cutoff. With KEY at 127 it plays in tune from the keys.
  • Envelope pages: ENV steps through AMP, F.ENV (the filter's envelope), M.ENV 1 and M.ENV 2.
  • A second mod envelope, with LOOP and its own destination and amount.
  • Modulator pitch: a modulator in MIX or RING is heard, so its RATIO knob becomes PIT1/PIT2 (−24 to +24 semitones). FINE1/FINE2 detune each modulator in any mode. New mod destinations M1PITCH and M2PITCH.
  • The editor and the CLAP plugin know all of the above. The editor and plugin need an FM-1 running 0.9 to stay in step.

Changed

  • Patch format 10. Older patches, patch files and plugin projects convert by themselves. A MIX or RING modulator takes its ratio's pitch (×2 becomes +12). Ratios of 5 and up are beyond +24 semitones, so those sounds come in lower than before.

Package identity FM-1_989. From ETCH: restore the official firmware first. If an FM-1 does not start after an update, hold OCT- while switching it on (the rescue updater). Community firmware, not made or supported by M-VAVE: install at your own risk. GPL-3.0.
