I'm writing a piece whose main instrument uses the granule opcode. I  
have tried every enveloping technique I know (including all four  
presented in The Csound Book) to cleanly fade the instrument out. But  
in all cases, at the end of the fade, the instrument just drops out.  
It will not fade to zero. It gets quieter and quieter and then...  
drops off a cliff. What gives?

I've never messed with granule, so this advice might not play out.

If you have an instrument that abruptly goes to silence prior to the end 
of the note, try creating a segmented envelope that zeros out the sound 
prior to the end of note.

Example:

a1 expseg 0.0001, (p3*.9), 1, (p3*.1), 1
ae = 1 - a1


Use ae as the envelope multiplier to create an inverse exponential 
envelope that goes to zero 90% of the way through the note.

Good luck.

Ha! That worked. Thanks so much.

I used the oscil technique to create the envelope from a table and  
made sure the table went to zero early as you suggested. Works  
perfectly.
