Here I show you how to upgrade your Roland GR-55 guitar synthesiser. You will first need to go to the GR-55 support page at the Roland website and download the new firmware. You can get that here:

You will then need a USB memory stick fomatted to FAT32 format.

1) Drag the GR55.bin file from the zip folder to your USB memory stick
2) Put the memory stick with the firmware BIN file into your GR-55
3) Hold down the “VLINK” & “USER” buttons while powering on the unit
4) The upgrade process should begin
5) When the screen says “COMPLETED” power down and restart your GR-55.

I hope this tutorial has been useful for you.
