Been tinkering with the GR-55 and trying to devise a way to have less tone dropout on patch change.
A better way, rather than patch changing, is to have the GR-55 remain itself on the same patch, and have
new patch data loaded into the GR-55.
This method has an almost seamless change.
So I present
"GR-55 PATCH LOADER" software,
a midi controlled patch file backup/bundle loader.
Where you plug in an external midi foot controller (or any midi patch change device),
make a patch backup file of your GR-55 (only the first 128 patches are accessed), and load the file into the software,
select your midi input and output devices, and away you go....https://sourceforge.net/projects/grfloorboard/files/GR-55%20Patch%20Loader/
there is one for windows, one for mac Sierra, and one for Linux Ubuntu 64.
