Resolume Forum

Brand new Acer Predator Helios 18 (Model PH18-73-90A6), running Windows 11 25H2.

MIDI devices will not be recognized unless resolume restarts with the device plugged in, and then will only take input but give no output*.

*Asterisk because the above issue was with two separate APC40 MKIIs, a Midi Fighter Twist, and a Midi Fighter 64, but midi output works on a Traktor F1.

With all of the midi devices above....
-If the device is disconnected from the machine, resolume will crash.
-If the device is plugged into the machine while resolume is running, resolume will not detect the device even with a refresh.

Solutions we've attempted....
-Disabling USB power management
-Updating all serial, USB, and audio drivers to a known working version
-Downgrading resolume to known working versions and even 7.0.3
-Powered USB hubs

Lastly, all midi devices are working as intended with Pangolin Beyond so we are thinking its resolume oriented.

Trying to figure out how to attach the log file, or I could just do a huge reply with it :/

Zip the log file, then it can be attached.

If you see the crash again, please use the reporter dialog with your email to send the crash data. https://resolume.com/support/en/reporti ... rt-a-crash
Thanks!

Are other applications running which could be using the midi devices?

Attached!

Also I missed the question regarding other applications....

No there are no other applications that should be utilizing midi ins/outs.

Yet another reply...


It seems like this issue may be more widespread than I expected. Evidence is pointing to a Windows Update issue. Microsoft is rolling out a new MIDI Services update (KB5074105) that seems to be breaking things with lots of different MIDI devices. Links attached below:

Additionally, here is the GitHub page with the reported issues:
https://github.com/microsoft/MIDI/issues

Maybe this issue deserves a larger thread as a public announcement to not install this specific update?
I've confirmed with other windows machines that MIDI works as intended when the update is not present. There is a tool released by Microsoft to confirm if this update has been installed, linked below:
https://microsoft.github.io/MIDI/


Unfortunately, the machine in question when we started this thread had the update pre-installed so we're unable to remove that specific feature update. Shortly we'll be rolling it back to an windows 11 version prior to the problematic update to see if that is in fact the issue. Will update afterwards.
