If I understand this correctly, I would use an envelope for that. So  
when the key is pressed the envelope fires up, and when the key is  
released, the oscillator will stop at the end of the envelope's  
release time.
You may want to have a look at a chuck template for polyphony I wrote  
a year ago for a workshop. You'll find it at http://www.lullcec.org/chuck/template_polyphony.ck 
. At that time it was working, not sure now. Be aware that envelope's  
release time is set quite long (1::second).

hope it helps,
