Many thanks Rikki for the URL. What attracts me to XGWORKS (still)is that it should have "better compatability" with a Yamaha KeyBoard than other mainstream programs. (Or is this not really important anymore?) I am currently brushing up on my sysEX and then I will try, as you have suggested, to observe what's going on. Are there any mainstream programs which include (even as plug-ins)brand name keyboard (Yamaha, Roland etc.)sysEX and other "brand" specific data. I guess I am looking for "the" universal program (if it exists) that will work with any k'board.
