Not much here except a pic and a sound demo. Stupidly sold this one…
Nanozwuerg, nanozwargh – the clip above shows a little mod (VCF input boost) and the awesome SVF of the MFB synth.
Heater core VCO, digital noise, cmos-based sub osc, and heckloads of OTA-based VCAs for level, modulation intensities, etc. VCF is a classic SEM-style SVF built around two lm13700S and the main VCA, again, is based on an 13700 OTA cell.
Well, with a bit of luck Imma score a Nanozwerg MK2 soon, so the quest will continue.
