Hi - I just bought a JV 2080, and have connected it up to my A80. I'm just at the point of running through all the onboard sounds to check what's there. When I select the blue "Perform" button on the JV2080, the sounds can be heard through my cab or headphones. However, when I switch to "Patch" on the JV2080, although the Midi light flashes on the JV2080 panel, no sounds come out of the headphones or speaker. Feels to me like a midi parameter needs to be altered. Any ideas gratefully received! Thanks David
