Trimming Potentiometers Overview
Name Function Explanation Factory default
P17 VCO Scale adjusts the 1V/octave characteristics of the
socket "VCO F" or the bus CV adjusted to 1.00V/octave
P18 VCO Offset adjusts the VCO frequency offset 64 Hz @ center position of the VCO Tune
control and Range switch in center
position
P19 VCO Octave Switch + adjusts the upper position of the VCO range
switch (+ 1 octave) adjusted to +1 octave
P20 VCO Octave Switch - adjusts the lower position of the VCO range
switch (- 1 octave) adjusted to -1 octave
P21 VCF Scale adjusts the 1V/octave characteristics of the
socket "VCF F" or bus CV (if the tracking
switch is in the lower position "full") adjusted to 1V/octave, VCF in self-
oscillation (Resonance control fully CW)
P22 VCF Offset adjusts the VCF frequency offset ~ 10 Hz @ CCW position of the VCF Frq.
control, VCF in self-oscillation
(Resonance control fully CW, all VCF
modulations off)
R23 Minimum VCA level adjusts the minimum VCA level (i.e. when
VCA A control is fully CCW and all VCA
modulations are off) 10k (a smaller value leads to a smaller
minimum VCA level)
