Nice work. I think also Envelope will do the trick. A fun chuck  
workout is also to define your own envelope. You could either make an  
object that extends Ugen or write a function and spork it. That way  
you could send two arguments for the beginning index and end index of  
the sample to playback and then just do something like this:

startval => sample.pos;
(endval - startval)::samps => now;
sample.samples() => sample.pos;

Make sense? I use this little bit of code all the time to make  
glitchy little things that crackle and pop when I start and stop the  
sample. You can put this through a low pass filter to take the edge  
off if you like.

Hooray for threading!

Happy ChucKing.
