This worked for my launchcontrol xl but the problem persists on the midi fighter. When doing this with the midi fighter, the driver install fails (error code: 10) and goes into a feedback loop trying to connect. IF it installs properly (idk why it does sometimes and not others - nothing changes), it forces a computer restart and goes right into the feedback loop.
If installing the generic audio, midi-in works but not midi out. Cant get ACX driver to work for the midi fighter at all. I tried using DJTT's Midi Fighter utility tool to assure updated firmware to no avail.
