Midi output seemingly not working from device?

Hi there,

I've built some live performance software in UE5 that is controlled with midi and have been unable to get my Monogram controller to output Midi to it consistently. At one point I had it connecting only if I reinstalled the firmware for the device, but since the latest Monogram Creator software update I'm getting nothing. I know that my code is working well as I have tested the Monogram with a build of the application (whilst the Monogram was still working).

I would use UE5's Midi remote control protocol to connect my device, however I can't get this to work in a packaged build of my project.

Has anyone else any experience with this - or can anyone possibly help me to troubleshoot?

Here is a video of my controller not working...

All the best,

James
