Thank you all for your input.
David that seems overkill, but I guess it depends on the workflow.
I am leaning towards an octave switch, fine and coarse pots. This trimmer
idea on the PCB is pretty good, it should be useful when tuning the v/Oct
response. The digital switch system is good on paper but probably not worth
the hassle. I'd rather use that surface for some extra functionality, like
sync. More about that in another email, hopefully in a few days.
