Back in 1987, this rackmount module arrived as the rack version of the DX7II, packing the same legendary six-operator FM synthesis into a compact 2U chassis that weighed just under 5kg, letting producers stack serious sound power without eating desk space.
It delivers 16 voices of polyphony across eight multitimbral parts, where you can link tone generators for anything from 2-note instruments to a full 16-note polysynth, all driven by 32 algorithms, sine wave operators with coarse/fine frequency, detune, key sync, and deep envelopes for pitch, amplitude, and level scaling. Controls include dedicated Voice Edit modes for FM parameters like feedback, LFO waveforms (sine, triangle, saw, square, random), velocity and aftertouch sensitivity, plus microtuning options and a cartridge slot for 64 extra voices or performances—far handier than MIDI dumps. Outputs shine with four stereo pairs and eight individual lines for precise mixing, though you'll want MIDI for volume tweaks since there's no onboard knob.
Over the years, players have praised its sharp, expressive FM tones for horns, strings, and beyond, with a huge free patch library keeping it fresh, even if the programming curve stays steep without editor software—many call it a DX7 sound in module form that's perfect for sequencing rigs.
