This seems like a sensible approach, since the use would be similar to an 
effect rack. An additional disconnect opcode would be useful: one might want 
to concatenate several instruments and produce only the final sound.

Actually, I must say I was thinking originally in an addition to the sco 
syntax: allow outputs to be saved to variables which would then be passed to 
other instruments as pfields.
