Mac and Ron, thanks for your replies. I am going to check everything out that both of you have suggested here because I really want to get this thing working right.

Ron you are correct in that MME seems to introduce unacceptable latency. But so far it's the only one that I've been able to use and still get sound out of RB. I've tried some ASIO drivers but have had trouble. When selecting/highlighting them, sometimes RB will just crash. Then I'll reopen the program and try again and they will "take", but none of the ASIO drivers allows me to get playback sound from RB, only with the MME driver. Here is what shows up in Audio Settings for ASIO selections:

ASIO DirectX Full Duplex
ASIO Multimedia
ASIO4ALL v2

input: (0,1) Realtek HD Audio output: (0,1) Realtek HDA SPDIF Out1 & ....

As for MIDI, I have the following output selections:

Microsoft GS Wavetable Synth
Microsoft Midi Mapper
(I have the "Reroute Midi Playback to Default DXi/VSTi Synth" checked, and the default = VSC DXi)

Maybe I'm wrong about this, but I was under the impression that you have to select/highlight one of the other output selections (Microsoft GS Wavetable Synth or Microsoft Midi Mapper) first so that midi data would get re-routed from there to the "checked" DXi/VSTI synth. Is this wrong? Anyway, I get no playback sound at all if I don't select one of the output choices such as the " Microsoft GS" one first. If I make no selections there and just check the "Reroute to DXi" option, I get no playback sound at all.

Anyway, I really appreciate the time you guys take to help newcomers such as myself. It really is a great program overall and will be very useful to me once I can get it operating correctly. Thanks so much.
