Ah - sorry, I didn't realize that we were thinking more or less the same. :-)

That would be cool too... but I was thinking of a row of step knobs
with pots (not switches) whose values get quantized to the nearest
allowed pitch in the infamous bank. And the pitches in the bank can be
switched to OFF, making them disallowed, causing all the steps that
happen to be quantized to this pitch to find another allowed pitch.
