29 knobs. If anyone speaks German, let us know know what he says about the synth. I'm curious what the circuits are based on.

Update: some info from strogon42: "Kurt says in the video that it's modelled after a Minimoog with discrete circuits (no special ICs), but he mentions only one oscillator specifically (but later you hear a second one), a filter (ladder presumably), vca and two envelopes, which are ADSR not ADS. The oscillators have switchable waveforms, octave selectors and frequency (LFO or third oscillator?) and pulsewidth modulation. There's also portamento. There isn't much information in the video."

Update2: and some info via Kurt Diedrich in the comments: "The snthesizer has two identical oscillators indeed and in addition an extra LFO. The envelope is ADSR for VCA and VCF and the filter has 24 dB/octave, realized by OTAs.
