Alesis Fusion 8HD Not Responding to Program Changes

I have a Fusion 8HD that I "drive" with Sonar 8.5.3. I'm having to completely rebuild the .ins instrument def file from scratch. When I finished the 1st bank, I was trying to test changing the programs/presets from Sonar, but the Fusion doesn't respond at all. I've verified that the Fusion is setup properly in the MIDI setup. I'm also posting this same thread at Alesis. Any ideas? KC
