I seem to be having issues with the volume +/- controls on this surround processor.

The volume codes included in the master.cml don't seem to work. I've managed to borrow HEX from other sources and drop them into a custom cml though not with 100% success. One code gives +/-1db control but won't sustain when the key is held. Others will sustain but jump +/-3db with a tap and swing unpredictably when held.

Anybody have any experience with this device? Is so, any suggestions/help would be appreciated.
