Custom SF2/WAV oscillators: Supports user provided SF2, WAV and proprietary DWB files for any of the three oscillators.

Arpeggiator: 32 steps, tempo sync, bipolar swing, 3 trigger types and up to 10 different modes.

Filters: 13 different filter types, 2-pole and 4-pole each with selectable tahn, poly, asym1, asym2, asym3, hardlimit, polywrap, asymwrap, quantize and asymquantize shapes. Includes filter positive and negative drive, keytracking, selectable pre-post volume envelope stage and zero delay feedback filter mode.

Fat, easy, mix-standing unison: Dedicated Unison unit to make sounds spread across the stereo mix with selectable octave spread, voices, detune knob and panning spread controls.

Use Super 7 Unison mode with saw, parabolic, square, triangle or sine waveforms to get the classic Roland JP8080 modeled SuperSaw sound.

Flexible ADR curves: Up to 5 different envelope curves for extended shaping.
