The Sputnik Variable Waveform Generator is a discretetriangle core oscillator with waveshaping per output; an original design by Andrew Morelli inspired by Buchla designs.
The module features 5dedicated audio outputs - sub oscillator, pulse, sine, saw and triangle - and a dedicated animation control per output (excpet for the suboscillator). It also has a vco/lfo switch,both linear and exponential FM inputs with attenuators and excellent tracking.
Sine output features an integrated wavefolder, with the animation slider controlling the level of the folding. Outputs a standard sine wavewhen slider is down, and negative CV pushing the value below the slider minimum will cause the output to attenuate or duck, perfect for AM/Ring mod like effects or VCA effects! Output features a switch that alternate between symetrical foldering and asymetrical folding, with higher fold values creating higher levels of asymetry!
Slider controls the position of additional saw waves for an animationeffect, perfect for thickening or motion or supersaw like effects! Features a three position switch that determines if it outputs one, two, or three offset saw waves.
The triangle wave is processed through an overdrive circuit, with the animation slider controlling the amount of drive - Outputs standard Triangle when the slideris down, and like the sine output using negative CV to push below the lowest slider value will attenuate the output for AM effects. Features a switch for distortion flavors:
ODD: typical soft saturation overdrive on top and bottom peaks.
EVEN: an asymmetrical soft saturation overdrive– increases width anddrive of the top side while decreasing the width and overdriving thelower substantially less, producing more even harmonics.
Slider controls the pulse width. Center position produces a 50/50 pulse. Switchable between
EDGE: standard PWM between upper and lower wave cycles. Approximately10/90% duty cycle with slider.
CENTER: PWM between rising and falling edges of the pulse. Approximately10/90% duty cycle with slider.
Subocillator output creates a square wave, switchable between -1 or -2 octaves below the main tuning.
- VCO/LFO mode.
- Linear FM: AC coupled with attenuator.
- Exponential FM: DC coupled with attenuator.
- V/OCT tracking FM.
- Coarse and fine tune controls.
- SYNC: Hard Sync, works with any waveform for varied effects.
