Ok i picked up my replacement Euphonix today.
It switches on and off nicely now, haha :)
First issue: Unit was set to a specific ip address and wasn't recognised. This is not the default setting apparently so fook knows how it got there in the first place. I did rtfm to change it but it wouldn't respond. After trying all sorts of combinations I managed to get the dhcp settings back to default. Problem 1 solved :) I just hope they didn't give me B stock as a replacement
Second issue: Ableton live wouldn't hook up - the midi input and output was sort of greyed out. To fix this i changed the ports in system preferences and all was ok (fyi i have no other midi hardware attached). After that worked I then changed them back to how i had them originally and all was still ok. I guess this issue is a legacy from the previous unit and the uninstall process.
Anyway, all seems ok. I do have some other issues but i want to play a little more before i raise them fully. The main ones being fader response and accuracy.
