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.
