After having patched my lights and programmed numerous palettes and cues at some stage in the process when i cleared all and released all my cues my macs were still at 100% intensity. What i did in the end was save a palette for mac off and used this in the show between songs to avoid any issues.
Also I was finding when I had a playback which had the macs doing a shape when i brought the fader down to zero the shape would often continue even sometimes even after selecting Off and then the relevant playback. Is there something fundamental i'm missing in the programmimg process here?
Another quirk I came across was similar to the mac intensity problem but instead a few of my dimmer channels seemed to lock themelf on and I could only get them off by bringing their fader to zero and up then zero again but whenever I cleared the programmer their 'natural' state of 100% would resume. In the end i deleted the channel and repatched them and things seemed to work from there.
Any suggestions?
Cheers guys
