VCO1
The voltage controlled oscil-
lators (VCOs 1 and 2) produce the
raw audio waveform usually used as
the initial source for sound creation.
They provide cyclic audio waveforms
that can be pitched. VCOs usually
receive treatment from the VCF to
turn their basic tones into pleasant
sounds.
FINE TUNE
Controls fi ne pitch adjustment of
VCO1. Use this to tune VCO1 to your
other instruments or VCO2.
TUNE
Controls the course pitch of
VCO1. Range is about +/- 2 octaves.
Use this to tune VCO1 to your other
instruments or to shift the VCO pitch
up or down an octave compared to
the VCO2.
MODULATION
This controls the amount of modulation to either pulse width or pitch from the modula-
tion source selected by the SOURCE switch.
Turn this knob clockwise in increasing amounts to apply pulse width modulation (PWM)
to the square wave. This will have the affect of thickening up the VCO sound. Extreme
settings of modulation may result in the sound cutting out.
Turn this knob anti-clockwise in increasing amounts to apply frequency modulation
(FM) to VCO1. Use this for vibrato and trill effects on the pitch.
In a central position, there will be no modulation to either PW or Frequency.
