I'm demo-ing an Ion. I've been on an Expression 3 for 5 years. If I'm on a cue and channels 1-5 are at 50%,and I want to see what 80% looks like, I can hit channel 1-5 at 80 enter (on Exp. 3), then if I don't like it, I just hit "REL" (release) and it goes back to 50%, or whatever it was originally on the cue. On Ion if I do the same thing, but there isn't a "Release" button, I don't know how to do the same thing- to get back to what was originally programmed in the cue, essentially "un-capturing" the channels. I see where if you hit "clear" enough times to clear the command line, it'll sort of un-highlight the channels that were "captured" but the levels stay unchanged until you go forward or backward in the cue list. There's got to be a way, I just haven't found it yet.
Hopefully this is clear enough that someone knows what I'm sayin'...
