Midi-ox seemed to work well, but the Polaris isn't responding to the sysex. Paul, just to verify, in order to get the sysex to load does the upperfunction-loadall need to be enabled?

I have tried many combinations of midi in/out, cables, and settings. I'm continuing to see if I can get midi out working. Unfortunately, Creative Lab's website was down yesterday so I couldn't work on it last night. I found a few other programs such as sendsx, dumpster, and sysexbox while I was waiting.

Worth noting, when I select sounds I do notice that the slider options and selections change for each program bank. So no it sounds more like an output problem. With headphones and the volume all the way up I can hear a difference in the background noise with when I toggle the volume and make selections. Not quite the normal button "pop" I remember though. There is even a slight change in the audio feedback when I press keys.

Fingers still crossed... Looking into some repair options out of Boston as well.
