[sdiy] Suggestions for oscillator coarse control methods?

[Florian Anwander]

I think it depends on the intended use of the oscillator.

For a non-modular "musicians-synth", like a SH-101, with a narrow 
keyboard-range I'd choose always a rotary octave switch. Fine tuning 
range depends on, whether hard-sync or FM with a second oscillator do exist.

For a modular synth I'd choose a combination of an octave switch (rotary 
or toggle) and a fine tune knob for which the range can be switched 
between a +/- 7 semitones  and +/- 8 octaves. I have all my Doepfer A110 
modified like that and I am very happy with it.
