So we were doing some programming the other night on an Express 48/96 for our upcoming show (yesterday/tonight/tomorrow actually) using 2 MAC300's and a MAC250. I have them loaded into the board using the profiles that I believe I downloaded from ETC's website (I got them last year so I'm only pretty certain that's where I got them; had the same problem then also). Through the course of programming we would run and clear cues and go back and whatnot (the usual back and forth trying to get transitions right), and occasionally the issue would pop up that the channels for the ML's would not clear. You could clear the cue, hit release, capture the channels/change the levels/release, I tried everything I can think of, the ML parameters wouldn't let go, they would all stay at their values in purple on the Stage screen. The only way we could clear the values would be to run a cue that we created which brings all the ML channels to Full and then clear that, though that only worked most of the time. Just running a different cue where the lights are programmed normally would only allow the values that changed to get released when you cleared the cue. Conventials did not experience these symptoms at all. Before programming I did a reset on the whole board as it's a rental and had some of the settings configured oddly, so everything should be set default. Am I missing a setting somewhere or is there something in the Fixture Profile or do I just have a bad board? On a seperate note, the MAC300's we had kept experiencing a FbER error (A feedback error on the pan/tilt). After swapping out 3 different 300's, we asked the tech if we were doing something wrong to be experiencing error after error, and he told us that if you strike the lamp while you're in a cue the fixture won't accept the DMX signal correctly, so the solution is to not strike the lamp while in a cue. Granted, it has worked, but being the engineering/software guy that I am, that answer doesn't make any sense to me. As far as I see it, striking the lamp is just a command that the fixture interprets, everything else should be independant. Is there any validity to that answer?
