There are two trimming potentiometers labelled "CV1 OUT SCALE" and "CV2 OUT
SCALE" on the Dark Time interface board. But before you try to readjust
these trimming potentiometers please measure the voltages. Exact +/-1.00V
voltage jumps should occur when the corresponding transpose switch is
operated. Only if you do not obtain exact 1.00V jumps the trimming
potentiometers may be readjusted to reach exact 1.00V jumps. Otherwise the
problem are the VCO(s) but not the Dark Time CV outputs. In any case a
precise voltage meter is required (4 1/2 digits recommended).
