A ha!!!! Toontracks? So there IS another one out there that creates backing parts! I was not aware of anything but Real Band and Garageband.

Garageband, btw , has some GREAT sounds included. I have already used it for some sweetening parts. The Rhodes is great. One of the string patches is quite flexible and the sounds can be smooth or course, envelope filters there for dynamics, etc..... The Hammond, which includes drawbars, is glorious. When I think that it's an iPad being controlled by an Akai Synthstation 49 and I can get that kind of sound from it... amazing stuff.
