Hi all I have recently got a DSL40cr and was hoping to run it 4cm with my boss gt10. I was also hoping to use the amp ctrl operation on the gt10 to control the channels. Has anyone achieved this? Also is there a way to change between the different modes as well as the channels using this? When I plug into the fs input from the gt10 it doesn't allow me to engage the fx loop on the front of the amp so the fx I the loop don't operate. I would rather not have to try and learn midi programming as I'm not that technical!!! All in all I need some help! I have searched through the forum but can't seem to find anything. Any help gratefully received.
