Need a refresher on editing SMFs

I went to add an older SMF to my playlist and found that only the drums played - channel 10. The other channels were firing but I was getting no sound. I have a few of these that I now remember will not play properly on Yamaha equipment. They will play on my Roland and my Power Tracks and Media Player.

I remember a discussion years ago about a SYSEX message that needs to be added or deleted, but heck if I can remember or find it. Can anyone help me get these files to play on my s950?

I've used Michael Bedesem's Midiplayer utility to make older files play on newer psr's. I think it can fix some issues and it also has a batch convers1on mode.

As to sysex, maybe you need to add a GM or XG reset at the start of the file? Having said that I just looked at the psr950 data list and there's no sign of xg reset. There's few GM codes such as F0 7E XN 09 01 F7 which is GM1 system on (I think you can replace the XN with 00). You may find big lumps of sysex at the start of the file, which can be fx setup or even custom drum tunings, if you aren't sure this stuff is Yamaha specific I'd delete it.

I think Michael Bedesem's MIDI Player II will solve all your problems - it's a great program.

Thanks guys. I found that the Yamaha MegaEnhancer PC app works great. It automatically gives you the opportunity to switch regular midi sounds to keyboard specific mega sounds. Whatever else it does it makes the rest of the file work perfectly on the 950.
