There are many instruments that in real life never
need a manual action to
stop their sound, for example most if not all percussion instruments and
drums. For these, sound can "only" be triggered and then just plays, there is
no way to stop it, apart maybe from rigorously damping it.
Damping notes on a percussion instrument is quite
a normal thing to do...
Apart from this, MIDI is very keyboard-centric,
and it shows in all sorts of ways. For example,
on any channel, note-on events are identified
only by their note number, so you can't have
e.g. two independent events of the same frequenccy.
I guess many synhts that have limitied polyphony
use the note-off event in the voice assignment
algorithm - if not the patch has to tell it when
a note has ended and the voice can be re-used.
So they may depend on it.
