Title: Note-off map broken?
Post by joeyhobbs on Aug 27^th, 2007, 9:40am

Hey y'all. I'm new to Midi-ox and am trying to expand the gate of my midi signals (from a drum kit).
Here (http://www.midiox.com/cgi-bin/yabb/YaBB.pl?board=query;action=display;num=1137111048)'s a thread which better describes the problem. (filtering out the note-offs doesn't fix the problem though)

When I tried to map a delay on all note-off events, it didn't work. I then noticed that a map for any note-off event is never used, and in fact maps for note-on events are applied to both note-on and note-off events. Is this a bug or am I simply being newb? Either way, does anybody know of a way to fix this problem?

Any feedback appreciated.

Joey.

"Note Off" can arrive as either Note On with velocity zero or as a "true" Note Off. (There's a good reason for this: MIDI allows the sender to omit the command byte if it hasn't changed; using velocity zero as note off saves a byte and thus improves timing accuracy fractionally. Or something...)

You're just mapping the input Note Off and Note On velocity zero to themselves but with a delay? Neat trick! :)

Ohh I understand now. Thank you so much for that vital piece of information :D

Cheers,
