The SCI Prophet VS uses 4 digital oscillators per voice (127 waveforms) and 4 pole LP analog filters. Big possibilities, instead of lack of a great interface. “Vector synthesis” at its best !
Kind of a Six-Trak on steroids, the Sequential Circuits MulTrack is a pure mid-eighties no-knob synth, but with great sequencer, filter, modulations and multitimbral capabilities it may be worth trying for accessing the famous SCI sound.
The SCI Pro One is an analog monophonic synth, similar in what a monophonic Prophet 5 would be. With 2 VCO (with layerable Saw/Square and Saw/Square/Tri waveforms) and a noise generator, 1 LFO (Tri/Saw/Square), 2 ADSR envelopes (routing to VCA and VCF), a mini-sequencer (2×40 notes), an arpeggiator (up or up/down), CV/Gate input and output, VCF and audio inputs, the most interesting thing is the modulation routing possibilities such linear FM, filter audio modulation, ring-mod like FXs, VCO sync… A must have monosynth in all synth’s lover setup!
