Mac,

Does this mean I don't need to do anything other than plug in the SD4, since the SD2 patch map is already installed in my BIAB and RealBand folders?

Also, for soloing with the SD4, while I am running MIDI files on the other sound bank(s), I'm planning on using a Godin Multiac SA guitar (synth access) with a Roland GI-20 midi interface, and then the SD4 for the sound. Does this sound OK? Any thoughts? Thanks.
