Hello.........I have both XGworks and PowerTracks. I still use PowerTracks with Band in a Box, but use XGworks for everything else. Since getting into Yamaha's XG voices having a CS2x and recently buying the PSR2000, I find XGworks easier to edit the XG stuff than the onboard instrument editors. Both programs allow me to edit the PSR style files, but XGworks allows changing XG parameters without having to switch between programs. I run Windows2000 and had to download a patch from Yamaha to get XGworks to run on this machine. Good luck!
