The Lighting Controller

Or you can try in a new fresh Windows user session (with or without default administrator rights ... ?)

I'll try with a new user session and let you know!
I don't have other midi devices with me, but as soon as I manage to get one on hand I'll test that too (a bit complicated with movement limitations currently in place in my area, so it might take some days to do so)

No changes with a separate fresh user session.
I've also tried to install other software that probably works in a similar way (Resolume) and the device doesn't appear there either.

Didn't had the chance to test with other midi equipment yet.

It seems your APC Mini is not recognized as a MIDI device by your OS. May be a driver problem or this kind ?
Here is my Device manager when my APC20 is connected (in french) :

I think so.
The Image is not visible. I'll post some screens of the Device manager too for comparison.

Device manager on my main computer (no issues here):



Device manager on my laptop (where the issue is):

OK, and what about the "Software devices" section of the "Device manager" ?

Software devices section of the Device manager (with the AKAI connected):


Screenshot is taken while ticking View>Show hidden devices, LoopBe (and the other midi routing software available on their website) was supposed to be fully uninstalled (as suggested in the previous reply)

I might have the chance to run a test with a midi keyboard (not sure about the specific model/brand) in the next days.
Is there something specific I should look at, other than see if it works?

Our experience with midi device says just plug and play.
So we presently have no other ideas.
Sorry for that.
