Paul,

The MusicLab thing will hook your keyboard to your computer and back to the SD2 again, so you can get synth sound. I find it useful for testing MIDI setups. But the little program won't change sounds for you, and the SD2, I suddenly realize, has no controls to change patches on its own. You could be stuck playing nothing but Patch 1 Piano, with that rig alone.

So you may find yourself better off using RealBand for a "host" and always playing the SD2 through that. It is not an unusual way to work. Though I gather this idea irks you at the moment, it does have advantages -- like absolute control over a MIDI module and all the effects.
