The Vr stuff is older, from pSpectra.  The Gr stuff is newer.  In general,
use the Gr, unless there is no appropriate class, or if the Vr is used in
one of the example programs.  If you ask about specific classes, I can
suggest which to use.

For audio, you can use either, but I'd suggest the Gr version.

Good plan.  Let me know if you need any more help.

There have been some delays outside of our control, but we should be getting
boards on Monday.
