The quantizer has no offset adjustment. An offset of 7mV is less than 1/10
semitone and could be compensated if necessary very easily by the (fine)
tune control of the VCO controlled by the A-156. If you need an offset of
less than 7mV a trimming potentiometer and resistor has to be added. But so
far (the A-156 is available since 1998) nobody complained the offset.
