brutal-fm

• Four-operator FM runs through a 4x4 modulation matrix with self-feedback, two-way cross FM and negative modulation.
• Four character modes, METAL, GROWL, CHAOS and NOISE, push the same core toward bells, bass, runaway feedback or glitch.
• The MORPH knob sweeps continuously between sound A and sound B, routing included, without changing pitch.
• COMPLEX ARP builds a fixed 8 or 16 step pattern from only the notes you hold, and keeps looping it.
• HOLD, FREEZE, RHYTHM LOCK, PITCH LOCK, TIMBRE LOCK, REGENERATE and UNDO let you reshape that pattern while it plays.
• Forty factory presets and thirty-two user slots live on the FM-1, and saved presets return at startup.
• USB MIDI and TRS MIDI in take notes, CC, Program Change and clock, while USB audio records your playing.
