What Is It?
FIMM is an 8-voice, 4-operator FM synthesiser with an engine written from scratch. It does the bright electric pianos, bells, basses, brass and metallic tones of the classic 1980s FM keyboards – and then goes much further.
The X-MOD section adds cross-modulation, ring modulation and hard sync, driven by the mod wheel, LFO, velocity, aftertouch, random or chaos sources, for sounds that growl, clang, tear and fall apart. Morph glides one patch into another as you play, and there is a built-in arpeggiator, chorus, delay and reverb. It also imports Yamaha voice banks over MIDI SysEx: 4-operator DX100, DX21, DX27 and TX81Z banks load directly, and DX7 voices are converted too – exactly when they use four operators, and as the closest 4-operator match when they use five or six.
Features
- 8-voice poly or mono with glide

- DX-style LFO with delayed vibrato
- Arpeggiator, locks to MIDI clock
- Chorus, delay (clean, tape, ping-pong), reverb

How Do I Connect It?
- Connect your keyboard, sequencer or MIDI interface MIDI OUT to the FIMM MIDI IN (5-pin DIN)
- Connect the stereo audio output to a mixer, audio interface or powered speakers (line level)
- Optional: connect MIDI THRU to another synth – chain FIMM with KLAK or MALICE and play them as one rig
- Power from a 9–12V DC supply (9V regulated recommended, 2.1mm, any polarity – not supplied) or USB-C (phone charger or power bank – not supplied)
USB from a computer is for firmware updates; it works for playing too, but a computer port can add some background noise.
