Kraftzwerg MFB semi modular analog synth

via this auction

"A very nice and rare semi modular mono synth, it's perfect to pair with an eurorack system.

Quick descriptions of the modules you can also use with eurorack:

-Dual LFO (reset inputs, without connection in the CVs the CV pot define the amount of mod to the rate effected by the other LFO, creates nice modulations)

-Triple VCO (CV and octave switch for all the 3 VCOs, single outputs of the 3 VCOs, mixer, ring modulator, sync, noise, attenuators for pulsewidht modulation of the first and second VCO, attenuators for pitch modulation for all 3 VCOs)

-24 dB VCF (Lowpass Moog style filter, 2 CV for frequency and one for resonance all with attenuators, with no cable in input1 the pot define the amount of feedback going back into the filter)

-VCA (3 inputs, 2 CV with attenuators, 2 outputs, 1 with attenuator)

-Dual ADSR (envelope with attack, hold, decay, sustain and release, you can change to linear response to one of the two envelopes with a switch)"
