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. Sine: Slider controls the level of wave-folding. Outputs a standard sine wave when slider is down, full effect when all the way up. SYM: 98-99% symmetrical wave folding. ASYM: Increased asymmetrical wave folding as the effect level is increased. Sine Wave Fold CV: Positive CV increases the effect. Negative CV will duck the sine in a very exponential manner when the slider is low. Audio rate ducking produces a pseudo ring modulation effect. The slider behaves as an offset for CV and an attenuator is provided. Sawtooth: Slider controls the position of additional saw waves for an animation effect. Double: a double sawtooth wave. Max levels can exceed 16Vpp. Center Position: no animation, just sawtooth. Triple: a triple sawtooth wave. Max levels can exceed 19Vpp. Sawtooth Animate CV: Slider behaves as an offset; any CV level can be used. CV attenuator provided. Triangle: Slider controls the overdrive. Outputs standard Triangle when the slider is down, full effect when all the way up. ODD: typical soft saturation overdrive on top and bottom peaks. EVEN: an asymmetrical soft saturation overdrive– increases width and drive of the top side while decreasing the width and overdriving the lower substantially less, producing more even harmonics. Triangle Drive CV: Positive CV increases the effect. Negative CV will duck the Triangle in a very exponential manner when the slider is low. Audio rate ducking produces a pseudo ring modulation effect. The slider behaves as an offset for CV and an attenuator is provided. Pulse: Slider controls the pulse width. Center position produces a 50/50 pulse. EDGE: standard PWM between upper and lower wave cycles. Approximately 10/90% duty cycle with slider. CENTER: PWM between rising and falling edges of the pulse. Approximately 10/90% duty cycle with slider. PWM CV: EDGE: positive CV increases top side duty, Negative CV increases bottom side duty. CENTER: positive and Negative CV have same effect on top and bottom side duty reduction. Higher CV levels or CV + slider offset can increase/decrease the duty cycle to 100/0% for a gated VCA effect. SUB: -1 or -2 octave pulse.
