I ran into a very similar issue routing midi via USB channels from my NDLR through the MPC to various synths. Certain parts would only play if others were stopped. I tried the same tests using MIDI cables instead of USB, and none of the NDLR channels worked.
I downgraded, and now everything is routing correctly. Hope they fix this soon, as I was really excited about the probability and ratchet functionality. Please let me know if I should provide any additional details.

On MPC One there are 3 tracks. All of them receiving midi from a Digitone Keys connected via an USB-Hub (Overhub).
Track 1 receiving on channel 5 and sending it on channel 5 to a Hydrasynth.
Track 2 and 3 receiving on channel 7 and 8 and playing an individual instance of the Hype plugin.

The thing is, track 2 is only playing the Hype as long there is no incoming midi on track one. The moment the MPC receiving midi on channel 5, the playing of track 2 stops.
In the midi monitor I can see that midi messages are still received on channel 5, 7 and 8, so I guess the problem lays within the MPC.

Any ideas?
After I did a downgrade to 2.10.1 everything is working as expected. All midi tracks now playing simultaniously. So for me 2.11.2 isn't usefull at all. Maybe 2.11.3 will be …
