If a composer is using percussion sounds on a non-percussion MIDI channel in GM/GS mode, then its up to them to ensure that the note durations are long enough. At least as far as the standard is concerned, which is what we should follow.

Thanks for explaining the true nature of the problem--I misunderstood.
I would like to propose the following for the percussion track:

   * A note-off event received before the attack phase is completed
     would be delayed until completion of the attack phase, unless the
     attack phase is longer than 0.5 seconds.

I can't think of any cases where this would cause an undesired effect.
Most percussive sounds would have a very short attack phase, and the
sounds that would have attack phases longer than 0.5 seconds (cymbal
rolls, sound effects that fade in) would still properly respond to
keypress duration.

By the way, should this only be applied to the percussion track? What
about synth toms and similar sounds?
