how to get real-time, continuously variable, PWM LFOs. or; another neat
thing i thought of while trying to figure out something else, realized
that this is cool in its own way, and just now had a chance to test out.
enjoy...
LFO1:
wave: triangle or sawtooth
cords:
1: LFO1+- -> switch +100
2: switch -> *target*
3: DC -> switch +0 (controlled by #4)
4: MIDI-A -> CO3 +49-50
this produces a square wave with the duty cycle controlled by knob A (cord
#4). if cord #4 is set to +50, the pulse can be set flat. if set to 49, it
can be set to just a tiny pulse (probably 2%?).
of course, if you want something more rounded than a square wave just
change cord #2 and add one more cord:
cords:
1: LFO1+- -> switch +100
2: switch -> Lag0 +??
3: DC -> switch +0 (controlled by #4)
4: MIDI-A -> CO3 +49-50
5: Lag0 -> *target*
in this case, the range of cord #2 determines how much of the edges are
rounded off the square.
note to n00bs (wait a minute... i'm also a n00b): although this example
uses a knob to adjust the PWM, *any* controller(s) can be used.
