Yes, I found that is correct. Apparently, the default cc #'s for the eurekaprom's Pod configuration are not correct for the Pod Hd Pro X. You do, in fact, HAVE to use the cc #'s listed in the Line 6 manual, meaning you have to use the programmable (PP) configuration on the eurekaprom 3. It's a bugger to program without an editor for the computer! I may still get the Uno eprom since it's cheap, easy to install and there is an editor available. Thanks so much for the help and the added info! :)
