I agree with all sides that have spoken out on the "Range Switch" issue. 

The synthesizer is *not* inherently a keyboard instrument, nor should it
even be thought of as being equal tempered, or bound to discreet pitches at
all! It's the most flexible sound shaping device in the history of musical
instruments, and no design-time limitations or pre-conceptions should be
imposed on it, if it can be helped.

However, those looking for an octave or octave/fifths switch are just
looking for another degree of control, and controls are good things. I
certainly wouldn't modify my 300's directly, but I don't see the harm in the
separate module idea. Perhaps a generic bias voltage module with discreet
outputs that can produce the 0.5v steps needed for octave switching.

Actually, I've been 'hankering' for a flexible quantizer module to turn
continuous voltages into very accurate discreet ones (one not limited to 12
notes per octave, something adjustable for accurate microtonality). I wonder
if somehow a quantizer and a range controller for VCOs could be combined.
Haven't thought this through, just tossing in my $0.02.
