Lost MIDI functionality in latest firmware

Bug Reports and Fixes
1

I’ve lost MIDI functionality in the latest firmware. I’m using my PC (Ableton) as a hub/host and MM in device mode for MIDI over USB. This all worked swimmingly in 2.3.0 but now I cannot get any MIDI recognition when I add the Rackcore MIDI to CV before other modules in a patch and cable accordingly. I’ve tried both the “Device” and “Auto” USB settings, to no avail. All my other rack modules are receiving MIDI fine, including some others receiving MIDI over USB. Any idea what could be wrong?

I do see the MIDI signal activity going to my External Device for MM in Ableton. The MM also reports that it is connected to a MIDI host. Nevertheless, MIDI is not recognized. Could I have accidentally and stupidly tweaked something I shouldn’t have?

I have not yet tried reverting to 2.3.0.

Thanks for any help you can provide.

I got this sorted after a bit of trial and error. For whatever reason, the update had rendered the Ableton MIDI template I use for my rack unusable and the communication with MM (only) had been compromised.
