Based on the 1978 Crumar DS-2 that featured a monophonic DCO synth engine paired with a 44-note fully polyphonic (paraphonic) companion section, two LFOs, 24dB 4-pole VCF, two ADSR EGs, and a hardwired five part LFO mixer.

Improved Synth section: monophonic mode with last/high settings, Unison, and Multi voice options (including voice cycling, panning, and tuning). Polyphonic capabilities with 4, 8, or 16 voice options.

Improved Poly section: now fully polyphonic, accommodating up to 32 notes.

In addition to the layered mode, there is a keyboard split mode for the Synth and Poly tone generators, featuring adjustable ranges for both splits and layers.

Two oscillators based on the digitally-controlled oscillators of the original, with stair-stepped waveforms for sawtooth, triangle, square and pulse waveforms. OSC 2 in the Synth section now includes a matching stair-stepped sine waveform option.

Oscillator sync added.

An third LFO has been added to the original two, offering ramp, triangle, sine, square, sample & hold, and staircase waveform options.

LFOs have been enhanced with discrete delay knobs for each, replacing the previous global delay knob.

LFOs now include sync, retrigger, and one-shot capabilities, along with reverse wave options for LFOs 1 and 2.

The LFO Mixer, which was hardwired to OSC 1, OSC 2, VCF, VCA, and Pulse Width in the original, now features six assignable destinations with 33 options each.
