Dear Dieter,

I now have the Quantizers back from the shop, but they are still
out. Both scales (All) track accurately (using a MIDI Keyboard and
Kenton Pro 2000 as the CV source) but the CV outs change at the wrong
points when in chord or quint. For example, on one, the major chord
flips on the root, the third and the sixth (not the fifth). Also, the
output of one quantizer is almost one semitone below the other (all
other things in the signal path being the same).

To this end, I need to try myself. Based on the Version 1 board and
with respect to your instructions, below, can you explain where P1,
P2, P3 and P4 are, please.

Next to the TL062CN chip = P
The small Pot next to IC6 = P
The pot (of the pair) closest to the CV and Trig out Sockets = P
The pot (of the pair) closest to TS274CN chip = P

Many thanks,

Stuadh
