The VCO is the primary sound source within SPAWN.
It creates the raw waveform which is then processed and
modified by the other synthesizer circuits.
SPAWN contains a temperature compensated oscillator,
conforming to the industry standard logarithmic IV/OCT
response. For ease of control an internal patch from the
Midi/CV interface has been routed to a CV input of the
oscillator, it by passes the Glide control so that the Midi
keyboard controls the level of the Glide. This internal
route can be isolated using the Midi routing switch in the
Midi section.
FREQUENCY CONTROL
1A. In the ‘-2’ position the Tune knob controls the initial frequency of 16Hz by +/- one octave.
1B. In the ‘0’ position the Tune knob controls the initial frequency of 64Hz by +/- one octave.
1C. 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).
