Logic Pro X Logic randomly changing MIDI IN/OUT configuration mid-session

Hi Group.


Strange problem here with my Logic X set-up. For some reason, Logic senses and changes the number of MIDI ins and outs available on my system at random unpredictable times - sometimes mid-song messing up what I'm working on.

I have the UNITOR-8 drivers and am using 4 UNITOR-8's as well as an NI interface in the AGGREGATE mode for MIDI / Audio. The NI and an Apogee Ensemble Thunderbolt are the audio interfaces.

Seems like something is happening on the MIDI bus that Logic is auto-sensing. Have used this setup for many years and have upgraded along the way - problem has been with me for some time but not sure when exactly it started.

Any ideas how to fix?

TIA!

Any chance you have Bluetooth MIDI enabled on some iOS device that comes near? I have had my iPhone decide it wanted to "play" and change things up a bit. My MIDI environment is much simpler than yours.
