Hi, Andrew -

I'll give it a try as well (to re-install), but I don't think that's the problem, because it also happens in RB 2009.5 and PTPA 12. BIAB works fine with the XMIDI, however.

The same XMIDI interface using Vista drivers (obviously under Vista) on the same machine (it's a dual boot between XP and Vista) works fine with PTPA and RB, as well as BIAB. It's just under XP that it doesn't work. My other computer has the XMIDI 1x1 and it has the same problem. Unfortunately, I can't test Vista on it, only XP.

Again, when I select the XMIDI (to which my Ketron is connected), I see some activity on the Ketron, because the activity light blinks, but then RB tells me the port is not available (however, it was on the list of available ports). RB/PTPA is obviously checking the port differently than BIAB does.
