| The Control section. Modifies Controls voltages for oscillators and filters. There is a variable portamento, called "glide" for the pitch control voltage. Otherwise the cross-mod and filter control voltage may be taken from any mix of oscillator 1 and noise. The Oscillator section has three oscillators, one of which may send control voltage that may modulate the two other, or the filter. This will act as both LFO and cross-modulation. There are six octave ranges and six waveforms for each oscillator. | ![]() ![]() |
| The Mixer mixes the three oscillators with further two input sources: Noise and external input. This is the chance to apply the famous Moog filter to any sound. Mixing the oscillators really is the source of a large variation of timbres. | ![]() |
| The Filter section is the famous moog resonant filter. Control of cut-off, resonance and amount of control voltage. The section also has its own envelope with attack, decay and sustain. Release is 0 or the same as decay, flipping a switch. The control voltage is mixed with 0,1/3, 2/3 or 3/3 keyboard follow, through two switches, or with the control section voltage through another switch. The Loudness section is a voltage controlled amplifier with its own ADS(+R) envelope. Again, decay is release at flipping a switch | ![]() |
| This panel is really a part of the control section. The pitch voltage has its own wheel, and the control voltage output has its own wheel. The lower switch is the beforementioned "release" switch, while there is another switch to turn on/off portamento which on a Moog is called "glide" | ![]() |
