Is the user going to notice that by an info message?

If the attack is a little too long, the sound is normally not cut off 
but moving on to the release phase, so it would just have a somewhat 
lower volume, rather than sounding "cut off".

That would not help ticket #1 though, since we never get through the 
attack phase, so we start release from a volume level of zero = no sound.

Perhaps, but MIDI files to not pass through the MIDI router currently. 
Should they do that?

That's well spent time as well :-)
