Noise/EXT1 level
Turning the control clockwise in increasing amounts sends the signal (if any) coming
in off the rear panel EXT1 socket to the mixer.
Turning the control anti-clockwise in increasing amounts sends white Noise to the
mixer.
In a central position no signal is sent from the Noise generator or EXT1 to the mix-
er.
VCF
The voltage controlled filter
(VCF) is used to alter the tone of
the VCOs/Noise and is the heart
of what gives an analogue synth its
character.
There are 4 types of filter avail-
able;
Low Pass
High Pass
Band Pass
Notch Pass (variable between
Low/High)
CUT-OFF
This sets the cut-off frequency, the point at which the VCF will start to filter-out har-
monics.
RESONANCE
Resonance is a feature of adding feedback to the filter circuit. The output of the filter
is fed back into the filter input. Resonance sets the level of feedback. As the control is
increased to higher levels the filter will self-oscillate. The oscillation frequency is set by
