O VOLTAGE CONTROLLED OSCILLATOR
The VCO is the primary sound source within the MARS. It creates the raw waveform which is then processed and
modified by the other synthesizer circuits.
FREQUENCY CONTROL
1. In the ‘-2’ position the tune knob controls the initial frequency of 32Hz by +/- one octave.
2. In the ‘0’ position the tune knob controls the initial frequency of 128Hz by +/- one octave.
3. In the ‘W’ position (WIDE) the tune knob has a range of approximately 12 octaves.
The Modulation knob introduces either triangle, square or no modulation to the oscillators frequency
( a maximum of two octaves, from the VCLFO).
