Yamaha DTXpress/DTXplorer/DTXtreme

Hi,

	I'm a new DTX user, and I'm having problems downloading any of the kits 
(from DTXpression) that are bigger than 972 bytes, I get an Error-Checksum 
when I try to down load them from my PC to the DTX, but all the kit files 
that are 972 bytes load OK. Anyone know what I'm screwing up that this is 
happening?

Thanks very much for all of the previous messages, they have helped me a lot.

Best Regards
Michael G.
