Details / Features / Specs

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.
