Certain tracks assiging random MIDI channels to notes

Question

Well, not exactly random. With some consistency, when I record on certain -- but not all -- EXS24 instrument tracks, the recorded notes take on MIDI channel assignments other than the channel on which they were transmitted (by various elimination processes, I've confirmed that the problem is NOT with my controller keyboard). Moreover, notes that lie within the upper octave (e.g., the keyswitch octaves for low register instruments) take on the correct transmitted MIDI channel –- channel 1 -– but all other notes will appear assigned to MIDI channels such as 5, 9 and 13.
Deleting the offending audio object from the environment, then restoring it or recreating it, solves the problem for an individual Logic session, but (I think) upon reboot the phenomenon recurs.
Anyone every heard of or experienced anything like this. Solution?

Answer 1

Thanks for taking a look.
To answer your most immediate question, my transport verifies that I am transmitting on channel 1. Likewise when I set the controller to transmit on channel 2, it confirms receipt of data on channel 2. No effect on result. That is, funny funny MIDI jumping occurs. Ha. Not.
When you say "a ton of tracks", are you seeing more than the 7 tracks that I've preserved in the arrange window? There are indeed a ton of instrument objects, but I've deleted most of the tracks. If you're seeing more than 7, then we've got another layer in this mystery.
If you expand the view of the arrange window, you'll notice that the regions have names that indicate the origin of the data they contain. I originally suspect this had something to do with routing, hence the region name references to output assignments (e.g., bus 9 = ch 1). Later I realized out assignments had no effects on the process. At measure 40, you can see the ascending MIDI channels, with the arithmetic pattern continuing uninterrupted as I changed instruments.
See especially the "snare and new snare" track, where the data at first recorded in accord with the channel jumping, and where, after the assigned audio object was deleted then recreated, the data recorded on the correct channel. This phenomenon, by the way, rules out the controller keyboard as the source of the trouble.
Further confirming that the controller is not the problem is the fact that this weird MIDI channel arithmetic game does not occur in new sessions called up from a different template. There is something wrong with the file.
When you got MIDI channel 1, you might have been on the "fixed tracks" – "snare" and "EVB3". Try "bassi", among others. Meanwhile I've noticed another clue (if indeed there exists a decipherable cause): when I set my controller to transmit on channel 2 instead of channel one, all data records
By the way, does the EVB3 play for you? Not for me (but see my previous post about this little oddity).
