Comment 6 for bug 410750

I just hammered Mixxx 1.7.0 on Windows XP w/ 3.HDJS.2009 drivers (the latest) and could not midi crap out after about 7 songs fiddling with just about every control pretty much continuously.

Can one of you with an MP3 try clearing the output mappings, close, reopen Mixxx and try again. No LEDs should light on the device but controls should still respond.

I'm wondering if this might be the same problem we had with sending too many updates to the outputs (this was a problem during the Linux driver development).
