Moog Prodigy

Overview and Oscillator

KEYBOARD 32 (F-C) low priority keyboard with no velocity, 2 wheels. A quite compact synth, a bit cheap built, a kind of stripped down version of the iconic minimoog model D. The prodigy has been released in 2 versions, the first one (336A / BX336) lacks the CV gate interface but it still can be added following the schematics. 

Oscillator Monophonic structure with 2 quite identical, syncable, VCO:
- VCO1 features 32′ shapes: Pulse, Sawtooth and Triangle
- VCO2 features  4′ shapes: Triangle, Square and Sawtooth. VCO can be detuned 
Mixer section allows to mix OSC volumes

Filter, EG and LFO

FILTER a powerful 24dB/oct lowpass with cutoff, emphasis, and envelop amount, tracking generator. Of course auto oscillation!
ENVELOPE 2 x  ADS with shared DECAY/release for VCF and VCA, time is estimated between 1 msec to 10 seconds.
LFO single modulator frequency from 0,3 to 30 Hz with 4 shapes: Saw Up, Saw Down, Square, Triangle. Destinations are Pitch and Cutoff.

Moog Prodigy Technical Data

■ Temperature regulated ultra stable audio oscillators (Heated chip
■ Logical control panel layout with signal progressing from left to
■ Two voltage controlled audio oscillators, each with separate three
position octave slide switches, waveform selectors, and volume
Controls. Oscillator two has separate interval control. (Both
oscillators ore and two are tuned with Master tune control.)
Switchable oscillator synchronization.
Pitch bendwheel with easy tofind center position.
Can also be used to sweep sync.
■ Separate low frequency modulation oscillator with both triangle
and square waveshapes.
■ Variable modulation amount wheel Controls amount of vibrato,
trills, wah-wah and/or tremolo.
Separate filter and oscillator modulation ON/OFF switches.
Voltage controlled amplifier.
■ Patented Moog voltage controlled filter, 24dB/octave, with self-
oscillation feature.
Separate contour generators for VCA and VCF.
