[sdiy] Suggestions for oscillator coarse control methods?

[Neil Johnson]

If you're worried about panel space and still want an electrically
simple solution, perhaps a concentric switch/pot combination:

Switch for octaves, pot for sub-octave tune (+/- 0.6 oct to allow a
bit of overlap).

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.

Cheap. Temperature coefficient of potentiometers is not always quoted. Can replace with a small potentiometer for nudge-proofing but at the cost of playability.
