promidi 2.0 not sending note off (OSX)
Dec 11th, 2008, 9:37pm  
I'm running the promidi sequencer example, but im not getting any noteoffs sent. im using the IAC bus, and i've checked with  midimonitor and ableton live.

anyone have any ideas?

Hello,

I am having this same problem with IAC, too. I am running OS X 10.5.6. The only thing I can do to get around this problem, is to manually send the noteOff signals (noteOn with velocity = 0).

Here's an example of what I am doing:

 track.addEvent(new Note(50, 127, 500), 0);
 track.addEvent(new Note(50, 0, 500), 1);
 track.addEvent(new Note(49, 127, 140), 1);
 track.addEvent(new Note(49, 0, 140), 2);  

It is unclear, however, if this will be cross-platform compatible. I am a bit hesitant to code this way until I test proMIDI on several different machines (Windows and Mac).

Has anyone figured this out yet?

Hi.

I'm having the same problem too.

mrshiz111: Do you mean that this is just with the IAC-bus?

When I built a step-sequencer with proMidi I used a matrix to store all active MIDI-events, to be able to add and remove them from the track properly. Using this you can easily access the Notes, and I guess Note's getNoteLength( ) could then be used to create "NoteOffs" by using zero-velocity notes. This way you can still use the duration argument in Note. You would still have to write the NoteOffs yourself, but it should work.
