Dear all Csound Guru's,
	I'm working on an instrument based off of the feedbacfm.orc talked about on 
the list a week or so back.  What I've done is to add a sound in that 
evolves with the feedback.  This creates a great sound that changes over the 
length of the sound.  However, I'm trying to find a way to allow the sample 
to play unchanged for a preset amout of time, and then have the oscil start 
up and effect the sound.  Below is the instr and score so far, just to get 
the altered sound.  Still trying to find away to delay the oscil from 
starting.  If any of you Guru's could help, I would be forever in your debt. 
  Also, I can't remember who first designed the feedbac.orc and would like 
to credit him/her for instr design in my .orc and .sco.  Thanks alot, any 
help or suggestions are most welcome.

Tohm Judson
