The Sputnik Variable Waveform Generator is a Buchla inspired discrete triangle core oscillator. One major change is the inclusion of a hard sync vs. the typical triangle core soft sync. The module features 5 dedicated audio outputs (sub, pulse, sine, saw and triangle) and various animation controls such as built-in waveshaper, saw animator and drive circuits with attenuation amount inputs. It also has a vco/lfo switch, both linear and exponential FM inputs with attenuators and very good tracking.
