What FMER does
- Two engines are on board: six-operator FM with 32 algorithm diagrams and DX7 voice exchange, plus Virtual Analog.
- Virtual Analog offers sine, saw, square, triangle and noise with direct oscillator, filter and envelope work.
- Record notes or arpeggiator output after a four-beat count-in, quantized, into 16 patterns per project of up to 64 steps.
- Edit notes, rests and ties, copy sections and chain patterns, then arrange them across four song lanes with repeats and transpose.
- Shape sounds with a reorderable chain of filter, reverb, delay, chorus, phaser and drive, including four reverb models and synced delay.
- Eleven arpeggiator types cover Strum, octave range, latch, triplets, gate and swing.
- Mix four tracks with volume, mute, solo, FX routing, patch and pattern controls, next-bar launches and expanded waveform views.
- Keep 16 projects and two editable 64-slot instrument banks on the instrument, with 192 original sounds to choose from.

We couldn't tell which file in this release is the FM-1 one, so we didn't scan it.
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
