I've tried the suggestions here and nothing so far has worked.

My X-Fi Gamer card works fine (SB X-Fi Synth A and SB X-Fi Synth B), VSC DXi works fine, Forte DXi works fine. So, I can get sound from various sources with RB (and PTPA) under XP, just not from the XMIDI USB interface (to which the Ketron is connected).

I also went through and loaded pretty much every other MIDI application I have on my computer - WinAmp, Jammer Pro, One Man Band, Jazz MIDI Sequencer, GNMIDI, MIDI OX, and various utilities, as well as Band-In-A-Box - and they ALL work fine with the XMIDI 2x2 connected to my Ketron SD2. So, it seems that there has to be something wrong with how PTPA 12 and RB10 is reading/interpreting/whatever the port. BIAB has no problem with it; why do the sister programs?

Again, very frustrating.
