I only have the MIDI OUT cable connected to my roland now. I go into sonar, i turn the Local Parts OFF in my roland and i have no sound. i Turn the Local Parts ON, and i have sound. I arm for record, i don't have any control because i can't hear the metronome from Sonar .. but i record, i have NO echo ( yay.. )..and i stop. playback, no sound. Pull the midi out cable from my roland, reconnect it, no sound when i playback.I connect the MIDI IN to my roland too, i playback, It DOES play back but with echo, and some notes aren't played..and it's just not right. I don't know what else to do
