Description
The Phoenix / Shruthi CD 4069 is a midi controlled monophonic synthesizer, with a CD 4069 filter similar to the EDP WASP synth from 1978.
The synth voice features 2 versatile digital oscillators, a sub osc and a multimode WASP style filter with distortion. There are a plethora of modulation possibilities using the 2 LFOs, 2 ADSRs and 4 CV ins, all of which can be assigned using the extensive modulation matrix.
The kit comes with an easy-to-assemble acrylic case, with protective glass for the LCD screen.
