[sdiy] Panel fillers

[Tim Ressel]

Richard,

This is an interesting concept. Leave us expand on it.
Here is what I am thinking: an NCO that is run off of
the Midi clock using a PLL to make a 128x or so clock
to run the NCO. The NCO will have a sawtooth output
which can easily be turned into a triangle or sine.
Using an NCO allows us to adjust the phase of the LFO.
So you can make, say, a sine wave that cycles once
every quarter note and starts at 75% up the positive
slope.

Now for the fun part: The divide-by portion get
interesting. the midi clock is 24 ppqn. Divide by 6
yields 16th notes, divide by 12 gives 8th notes,
divide by 9 gives dotted 16ths. Is anyone going to
want a divide by 10? Should this an option? Or just go
with multiples of 6(9)?
