[chuck-users] coordinating rhythmic timing with unpredictable OSC events

[Tomtom]

I think your problem can be solved with a technique along the following
trick :

60::second / bpm => dur tick;
tick - (now % tick) => now;

if you add this at the start of your script, it will wait just long
enough to start on the next beat. that way, you can have several shreds
in perfect timing, even though they are triggered from an external
event.

hope this helps !
