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.


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.


The Variable Waveform Generator is 18 HP.
