GR-50

Hello all,

I've been mostly a lurker on this list and I've finally managed to 
move into the wonderful world of MIDI guitar.  I now have a GR-50 and 
I'm looking for a freebie patch editor.  

Failing that, if someone can point me to the sysex layout, I can just 
write my own.  

I have searched the net (and this list archives.)  I spent about 2 
hours looking, but all I found as far as editors is the MIDIQuest (I 
think that was it) one.  I found no sysex info however.

Any help or hints would be appreciated!

Thanks,
Tony
