What fm1-glider does
- Press a white key to latch a scale tone on, press again to switch it off, up to sixteen at once.
- Black keys glide the tone beside them by one to four scale steps, one click up, a double click down, the next click home.
- Two oscillators give warm voices with overtones, undertones, FLOAT motion, detune LFO and an interval voice that follows the key or stays pure.
- Twenty-two presets, twenty-five scales including chord scales, and equal or just tuning keep everything in key.
- Tape echo, ladder filter, delay and shimmer reverb sit after the voices, with tempo sync and tap tempo.
- Tap SEQ for a drum track of twenty-seven synthesized slots, sixteen steps each, with probability, ratchets, scatter and a COLOR knob.
- ARP rolls a completely new random beat, and PLAY starts and stops the drums.
- MIDI over USB, BLE and DIN plays the keyboard and drums, and MIDI clock sets the tempo.

Its file didn't open cleanly as an FM-1 firmware, so we didn't scan it further.
Les scans every firmware here whose file is public, and shows what it checked and what it found. A scan lowers the risk; it can't rule it out. This firmware is made by its author, not by Les or M-VAVE. Back up first, and install at your own risk. How Les scans firmware
