Interesting area - you will find that the A part of ADSR is crucial when it
comes to recognising instrumental sound. Remove the attack from the sound
and you will begin to have difficulty in telling the difference between
quite diverse instruments. An oboe and a trumpet will sound *very* similar
indeed. Place the attack of an oboe onto a flute and you potentially have a
hybrid instrument (either through a cut/paste method or convolution for a
more interesting sonic result).
