★ Four-part drum rack
Voice 1 = kick model · Voice 2 = snare model · Voice 3 = hat model · Voice 4 = percussion model · sequencer clocks each voice separately · stereo mix stays internal until the final output stage.

Wavetable thump
Voice 2 in wavetable mode · pitch CV quantized to semitones · decay short · wavetable select animated slowly for pitched percussive motion that sits between drum and tone.

Choked fill layer
Voice 3 and voice 4 share a choke relationship · rapid fill pattern on voice 4 interrupts voice 3 · use this for abrupt fills without needing external voice-stealing logic.

Behaviors

Three engines per voice select a model, sample set or wavetable bank

Each voice can act as a modeled drum, a sample player or a wavetable VCO. The same front-panel controls adapt to the selected engine.

CV and LFO assignment bottom page plus encoder

Each CV input or LFO can be assigned to pitch, decay, sample selection, pan or volume, with depth adjusted in 32 steps.

Gate mode hold enable GATE MODE in settings

Samples, wavetables and some models hold while the gate is high and only enter decay after the trigger falls.

Choke groups enable choke routing in the voice assignment page

One voice can be set to choke another, which is useful for closed-hat style muting and tighter drum articulation.

Random folders and step triggers uppercase RANDOM folder or CV step trigger setting

Folders marked RANDOM choose a new sample on every trigger, and each voice can treat its nearby CV input as a step trigger for sample stepping.

Internal mix and master dynamics mixer page

The module mixes four voices to two outputs, with per-voice volume and pan, master volume, three-band EQ and compressor.

Preset and memory-card workflow F-button preset page

The module stores 64 presets, supports copy/delete and can save or load presets to the memory card in firmware 1.12.3+.

Hidden reverb long-press encoder in EQ/compressor screen

A hidden reverb page is available and only feeds the main outputs 1 and 2.

Controls
