Prysm 1.3: a sequencer for every patch, a LIVE screen for playing out, and a keyboard split with two sequencer parts.
Install: the web installer (Chrome or Edge), or python3 tools/fm1_install.py prysm-1.3.fwsc. Manual: docs/MANUAL.md. Your saved sounds, patterns and song carry over: every used slot starts with a copy of your current sequencer, and the split starts off.
New
- A sequencer per patch: each of the 8 slots keeps its own patterns, song and drum kit. Changing patch while playing swaps the sequencer at the end of the pattern. SAVE stores the sequencer with the sound (also when saving to a new slot); LOAD no longer saves the patch you're leaving.
- LIVE screen (HOME twice), for playing live:
- The first 4 black keys pick patterns, the first 8 white keys pick patches (sound and sequencer together). Both change on the next bar line; press again to cancel. A pattern key during a song switches to PATTERN mode.
- Mutes on the keys above middle F: F#4 / G#4 / A#4 kick, snare, hats; C#5 / D#5 OSC 1 / OSC 2; F#5 the noise. Lit = on, flashing = muted. Not saved; an M in the header on other pages while anything is muted.
- Four knobs, your choice: K1–K4 can each be any sound parameter (SELECT picks the knob, PRESETS its parameter), saved in the settings.
- Keyboard split (MIX → SPLIT, saved per patch): below the split key only OSC 1 plays, from it only OSC 2: a bass under a lead. Each side has its own octave (±2); set the key with KNOB1 or LEARN (press the key). Still 4 voices, shared by both sides.
- Two sequencer parts (SEQ → PARTS): with the split on, the notes below it are part 1 and the rest part 2. Record one over the other, and mute (MUTE1/2) or clear (CLR1/2) either. Recording replaces only the part you play.
- Snare flam (DRUM: HIT after ACCENT): two snares ~20 ms apart, the second softer.
- From Dinghy 0.4: TRS MIDI IN and the update loader's progress screen.
- The editor and the CLAP plugin (1.3.0) have the split.
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.
