Cherry Audio's DS-2 is a meticulous software emulation of Crumar's 1978 hybrid synthesizer, capturing one of the earliest attempts to merge digital control with analog signal processing. The original hardware paired a monophonic synth section with a 44-note paraphonic polysynth, a configuration that Cherry Audio has faithfully translated into plugin form while adding modern conveniences.
The DS-2's sonic signature derives from its unusual oscillator architecture. Rather than the smooth waveforms of later digital synths or the warmth of true analog circuits, the Crumar employed digitally controlled oscillators that produced deliberately stair-stepped waveforms. Combined with the poly section's divide-down square wave technique and resistor mixing, this approach generates a characteristically jagged, harmonically complex timbre that sits distinctly between vintage analog and digital synthesis.
This timbral quality - gritty, edgy, and harmonically rich - makes the DS-2 particularly valuable for sound designers seeking textures outside the conventional analog or modern digital palette. Bass synthesis on the monophonic section yields distinctive aggression, while the paraphonic poly engine excels at shimmering, bell-like textures and evolving pad layers. The shared filter architecture between sections creates cohesive tonal blending when both are utilized simultaneously.
The plugin suits producers working in experimental electronic music, ambient, and synthwave particularly well, though its character proves useful anywhere unconventional digital-era tones serve the arrangement. Among available DS-2 emulations, Cherry Audio's implementation stands as the most comprehensive recreation of the original's hybrid design, making it an essential tool for those seeking authentic early-80s digital synthesis character.
