I just purchased my first oscillator without a wide range continuous
tuning knob. (It has an octace switch and a fine tune of +/-6
semitones). I find this arrangement frustrating and unsuitable for my
needs. In my opinion Plan B M15 has it right: Continuous Coarse tuning
and Fine tuning. And importantly the fine tuning is only +/-1 semitone,
which makes tuning actually precise and easy.

Of course, if there is an *additional* octave switch, I don't mind,
except that it takes some space. I would still propably rather use
something like 185-2.
