I don't think that your A-156 is crazy. You describe a basic "problem" with
each quantizer that is not embedded into the sequencer. A quantizer regrades
incoming voltages and does not "know" anything about a sequence and the
notes/voltages of the sequence (you could use any voltage as input of the
quantizer). If the new incoming voltage is very close to the threshold
between two steps (e.g. D and D#) the output voltage may sometimes
correspond to D and sometimes to D#. This could be avoided only by a
quantizer that "knows" that during the last sequence there was a "D" at the
step in question and that he has to repeat this "D" because there is only a
very small difference between the new voltage and the voltage during the
last run.

To obtain this feature the quantizer would have to memorize the voltage of
the sequenzer step in question during the last run and compare it to the new
voltage. If the difference is less than e.g. 1/24V (half semitone) the same
output voltage is generated as during the last run. This is possible only of
a "supervisor" is available that memorizes the voltages of all steps during
the last run and compares it to the voltages of the next run. But as A-155
and A-156 are separate modules that's not possible. Only a sequencer with
built-in quantizer (like the Dark Time) could offer such a feature.

It's a bit difficult to understand but I hope I could explain the
A-155/A-156 behaviour.
