Fran, this is the same file you sent before...

The problem is, it appears to have XG sys-ex in it, which is what the BK-9 manual SPECIFICALLY says you can't use. You HAVE to strip out the XG sys-ex, either in the BK-9 sequencer or any other sequencer/DAW.

Do you know where you got these files in the first place?

I have been Makeup Tool-ing my entire G70 SMF collection, and haven't YET found a single file edited on the G70 that didn't work fine in the BK-9. Including tracks that had been transposed.

This is a sys-ex problem created by having Yamaha sys-ex in the file. There's no way the G70 put that in, it must have been there from the beginning. Strip it out, the files work fine.
