A string of note-ons following each other all for the same pitch n without any intervening note-offs for pitch n, IS PERFECTLY ACCEPTABLE provided they are INTENTIONAL and NOT accidental. No. MIDI note-on represents a key press. Note-OFF - key release. There is no logical way a key can be

Hi, I'm pretty sure I've seen this dealt with on the list before, but can't find it. With the program I'm fumbling around trying to create, it will be possible for successive note on events for the same pitch to occur without note off events intervening. Does the MIDI spec allow such things?
