Hi there! I'm the very satisfied owner of a roland blues cube hot. I'm trying now to use the usb output on my computer. I've downloaded the driver for my OS so no problem concerning that. My concern is that the output from the amp is quite low on the track I've created on garageband. It seems like it's hard to obtain enough input signal from the amp to get a satisfying sound on the track. Am I playing too low? I've tried to turn the volume control and get a higher input on the track but it doesn't stay clean except if I turn the master but then the amp is loud in the room. Any idea of what can be done for that? Thanks!
