[PD] flip flop, pulse divider...

[Miller Puckette]

Here's one wy (in vanilla) -

Narrow the pulse to one sample wide (by clipping it and subtracting
a one-sample-delayed copy).  Multiply by something huge and clip~ it
so that te pulse is exactly (sample rate)/2 high.
Feed this to a phasor~.  The output will then toggle between 0 and
0.5.

Differentiate and clip~ again to pick off the rising edges of the
resulting square wave.

cheers
Miller
