Hi Guys
now that Windows 10 is rolling out I seriously suggest you check all your software is compatible before you upgrade.
It was only once I had completed the upgrade I found the GT-100 drivers are not yet available, so I cannot use the USB connection for patch changes and Boss Tone Studio.

My RC-300 works fine as the USB link is only for file sharing.
