I've just noticed that my A156 Quantizer is about a semitone out of
tune.  I tuned my VCOs against my Midi synth but when I play the 155
through the Quantizer, the notes are out.  Which of the four trimmers
should I attack (the scale is bang on one octave, it is just the offset).

PS still interested in how to have the quantizer play the 4th instead
of the 6th.
