[sdiy] Sequencer - "Human Feel"

[Tim Parkhurst]

Just a quick thought on an old thread (Jan 28th):

One proposed feature was being able to vary the leading edge of the
sequencer clock to 'randomize' the timing a teeny bit, but I don't
recall anyone coming up with a way to implement this...

You should be able to use a triangle wave, a couple of comparators,
and a little bit of switching to create a square wave clock where you
could vary the position of both the leading edge AND the trailing
edge.

Actually, you could probably do it with one comparator and some logic
to switch the reference voltage going into the comparator (one level
for the leading edge, another for the trailing edge). If you did this
right, you would have pulse position modulation in addition to the
familiar pulse width modulation.

Any thoughts?
