How long are the triggers in a drumtrack

[Againsistm]

Hi all,
Hope you are all doing ok! I just finalized building a tr-9090 and are sequencing it with a Midiphy. Everything works as expected. What i can't find is when you create a drum track and connect via midi. How does a trigger work sent from the midibox? A 909 except a 2ms trigger but i cant find anything how long a trigger is sent via midi? Is this adjustable? 

Thanks!!

Not sure for a 9090 but generally a drum sound has no sustain and triggers on NoteOn, Note duration does not matter, but NoteOff must be received between 5 and 10ms after, just to permit the same NoteOn to be received again.

Thanks now i understand.. The 9090 has internal triggers for each drum but the note on will be converted to a 2ms trigger by the 9090 midi implementation.
 

Thanks!
