Note off does not get suppressed

[bburtin]

I have two keyboards. One sends notes on channel 1, the other on channel 2. I don't want Cantabile to respond to channel 2, so I suppress it in the global MIDI filter. This works great for note on, but not note off. If I hold a note on channel 1 and then hit the same note on channel 2, my synth stops playing the note after I release the key. Is something funky going on with filtering note off messages? It's definitely filtering note on, because I don't hear the note if I hit the key on channel 2 by itself.

Hi Boris,

I just tried reproducing this but it seems to work fine. What sort of MIDI filter are you using?

As far as I know note off can be "funky" as there are two ways to turn notes off...

One is a special midi note off event.

The other mostly used is note on with velocity 0.

That can be confusing - maybe it's something related to this?

Hey Brad, thanks for looking into this. I have only a global filter that says "suppress notes on channel 2". Here's my MIDI-OX log, in case my controllers are sending data that you're not expecting:

And here's what I see when I put MIDI monitor in the rack in front of Synth1:

Code: Select all

Note On, Channel: 1, Key: 48 (C3), Velocity: 80
Note Off, Channel: 2, Key: 48 (C3), Velocity: 97
Note Off, Channel: 1, Key: 48 (C3), Velocity: 126

I'll also send you a copy of my rack.

...I suspect "Note off" is the unexpected... as said, most controllers send "Note on - velocity 0" instead...

Hi Boris,

I've just uploaded a new experimental build which should fix this. Please let me know how it goes...

Sweet! Thanks for the blazing-fast turnaround. I'll try it out tonight.

[bburtin]

Yep, that fixed the problem. Thanks again Brad.
