4. Controls
1 Range
Footage (the octave of the fundamental) is controlled
with this knob. Five settings are available, giving a wide
frequency range.
2 Tune
The TUNE control enables Fine Tuning of the oscilla-
tor frequency in a range of roughly
± ½ Octave. For
precise tuning, an electronic tuner is recommended.
P If two or more oscillators are controlled by the
same control voltages, and set to the same
footage, you can use the TUNE knob to
de-tune one or more of the oscillators relative
to each other.
This can produce vibrato and chorus-like
effects, perfect for soundscapes and gene-
rally rich timbres.
3 CV 2
The pitch of the VCO is controlled by the voltages
present at inputs " and §. The amount the control
voltage at input § affects VCO pitch can be controlled
with Attenuator 3 (see also §).
4 PW
You use control 4 to alter the pulse width of the square
wave appearing at output & (see Fig. 2 and &).
5 PW CV 2
The pulse width of the square wave can also be altered
or modulated by voltage control from inputs $ and/or
%
. The level of the PW CV 2 (input %) affecting the
pulse width can be set with gain control 5 (see also
%
).
