My MIDI controllers are routed thru my DAW (Sonar Platinum). Last night I finally got to audition my OB-6 module, and was blown away by its beauty - no problems. Tonight I wanted to resume, but as soon as I open Sonar the OB-6 module freezes on whatever patch it was on before opening Sonar, and I can't change any patch or parameters on the OB-6. When I push a a patch selection button, the patch number changes correctly, but nothing else - no other settings changes, and I can't change anything with the knobs. I can't activate the arpeggiator. It's like Sonar has locked every parameter except the patch number LEDs. The sound from whatever patch was set prior to opening Sonar plays fine, no matter what buttons I push. I'd swear that I have everything set up the same as last night when it all worked perfectly, but obviously something is different. I don't know whether to feel stupid or upset. I hope someone can help and make me feel stupid. Oh - I'm using OS 1.5.5.
