John,

Thanks for the detailed instructions. You obviously put a lot of effort into producing them. I tried to install MIDIYoke but it wouldn't install. I assume it's because I'm using 64-bit Windows 7. However, I found another virtual MID port application named LoopBe30, which did install properly and did provide the MIDI ports. Although I was able to set it up the way you described and select the MIDI port, I still get the message that says "Audio and/or VSTi/DXi Output will be silent. The ASIO4ALL driver is not connected, likely due to your using a soft-synth (like GS-WaveTable) for MIDI.", and there is no sound. What I ended up doing just to get past this problem was simply generating a WAV file for each MIDI instrument in BIAB, then importing them into RB. It's not a great solution but at least it will let me move on.

Thanks,
Ray
