Here's an procedure similar to what I use:

1. create a new instr to generate sync pops as in syncpop.orc example below,
I call it instr 1.

2. Create a separate sco file for each instr, putting all statements for
that instr in a second section, with their original p2 times. The first
section is the sync pop as implemented in syncpop.sco below. Essentially you
are padding the front of the composition with 1 second then putting a sync
pop at the beginning. 

3. In your multitrack editor (presumably a DAW type thing) line up all the
sync pops at the beginning, then cut exactly 1 second off the front of each
track.

Depending on the running time of your comp and the stability of your system
clock, you may need to divide the entire comp up into shorter, sequential
sections, to keep the tracks from drifting out of sync over time. In that
case repeat this procedure for all sections. I never do anything very long,
so I don't know about this last point. You'll just have to try it and see.

Hope this helps.

Hi all,
    I can't seem to figure this out.  How can one render the individual
instruments in an orc as seperate waves for post processing & mixing.
Thanks,
