I have a question for anyone who uses or has used an ETC Expression 3. We just got our expression like 1 month ago and we are just starting to program cues for our next show thats in 3 weeks, but we have been having issues with the board, it has completely frozen up on us on more than one occasion forcing us to turn the board off and back on, while we have yet to lose any data, we are worried about losing stuff and also if something like this happens during a show obviously it'd be a bad thing. My Professor's called ETC and they claimed that it was the fact that my laptop was hooked up to the MIDI and a keyboard were plugged in and that was causing this. I don't really believe this because for one my laptop hasn't been plugged in since like day two with the board and we have reloaded the firmware since them, it could be the keyboard, which is now unplugged so well see what happens with that, i was just wondering if anybody else has had this problem and what you did to fix it, thanks. Also the keyboard is an IBM ps2 keyboard with an adapter so that it goes into the 5 pin din.
