[sdiy] Re-inventing the knob (was Control Interfaces)

[Rude 66]

excellent! i'd be much more interested in a road like this than one that
emulates a real instrument as controller. this is theo ne field where you're
not stuck with all the limitations a real physical instrument has, like
size, material or anything like that.
there are also ways to make one knob do more things. you can have one with a
ring around it, sort of like the rec level knobs on recording decks, so for
instance one double knob can control cutoff for 2 oscillators. offhand, the
arp 2500 uses them on the oscillators. use them as 1 set of controllers for
2 osc's, filters, eg's, etc. or same thing can be done with those knobs you
can pull out or push in for an extra function.
