[sdiy] continuously variable swing

[gregory zifcak]

so the sequencer would set individual swing per step? wouldn't this method 
make your sequence length all wonky? i'm assuming the cv would speed up and 
slow down the clock on a step by step basis.

my aim is to get a steady clock that's a constant tempo, simply shifting 
every other step forward or backward in time. then i could jam on the swing 
live to dynamically change the feel without altering the tempo.

my only idea so far is to have a half speed clock triggering a one shot for 
the inbetween steps, then mix the clock and one shot together. the one shot 
length would be adjusted by the swing pot.

if possible i'd like to drop this in as a replacement for the existing tempo 
clock in the 707, preferably retaining midi/din clock out.

now that i think about it, the tempo clock has to be faster than 16th notes. 
maybe there's a way to do this using clock dividers? maybe the existing 
clock isn't fast enough to allow for fine swing adjustments though.

any thoughts?

thanks,
greg
