I made a little search but I found nothing.
I use two MIDI controllers: a Launchpad S and a Launch Control XL. The last one have two profiles on MPCTools, the first to control bank1 with the faders, the second to control bank2 with a row of knobs.
At start everything works always fine. Often, after some time, the Lauch Control goes off. It stay powered (led and everything) but MPCTools says "Could not connect to MIDI Device "LaunchcontrolXL" input".
The error is for one profile but the second doesn't work too.
