One of the very few remaining Crumar DS-1 on the planet, serial number 28. Recently serviced and recapped, this impressive monosynth works like a charm and looks great - far better than any other DS-1 / DS-2 available nowaday. Released in 1978 to compete against the Minimoog, the Crumar DS-1 implemented one of the earliest digitally controlled oscillators (DCO) - if not THE first. In those days this was enough to mark a synth as "Digital Synthesizer" but actually the DS-1 is a fully analog monosynth with analog controlled digital oscillators. A rocksolid synth that can easily genetare fat basses, expressive lead sounds and an unexpected range of percussive/FX sounds. So Crumar released the DS-1 (their first full-fledged synthesizer) in 1978, more than four years after Korg and Roland began their domination of the low-cost arena. Consequently, and despite its cool sound and features, everybody overlooked the DS-1 and less than 200 units were sold. The Crumar DS-1 is a dual-oscillator monosynth with a 24dB/octave resonant low-pass filter (inspired by the Minimoog Ladder), one LFO (assignable to oscillators, VCA, VCF and PW), Glide FX, two selectable noise generators and a useful Gate/IN. The front panel has a lot of well organized (and sturdy) knobs and sliders that make the DS-1 a very intuitive machine.
