Hi elle and Fran

Thanks for adding to the list. I should have followed elle's link, but I have not yet. I believe the SW1000XG is a PCI version of the Yamaha MU100. It seems like a good choice for a desktop computer with controller configuration. Since it accepts the Yamaha plug ins, it can even accommodate vocal harmony. I actually have the Yamaha MU100R, which uses the same sounds but comes with vocal harmony and VL synthesis built in. This is also a good alternative.

The original Sound Canvas's may offer the most cost effective high-quality sound module plus midi interface.

One issue for me is GM2 compatibility. I assume I want it, but I cannot find out specifically what it offers over vanilla GM. I believe it has an expanded ethnic sound set, including two Gamelan kits. If anyone knows more about GM2, I would like to hear about it. Anyway the new Rolands and the Yamaha MU128 are GM2 compatible.

By the way, has there ever been a rack mount arranger?
