Yes, an amplitude envelope will work.  Try this:

instr 60
   idur = p3  ; duration of note
   ivol = p4
   ipan = p5 * 1.570796327
   aleft, aright diskin "Grand/80/60.wav", 1
   aenv linseg 0, 0.02, 1, idur - 0.04, 1, 0.02, 0  ; envelope
   aleft = aleft * ivol * cos(ipan) * aenv
   aright = aright * ivol * sin(ipan) * aenv
   outs aleft, aright
endin

I haven't tested this code, so hopefully there aren't any bugs.

Best,
Jake
