Repatching a show without modifying cue list

The theater I work at has a Christmas show that is reoccurring every year with little change. This Christmas show has a different patch than the rest of the shows run here. Can I make it be the same patch without needing to fully redo the cue list?

  • Let me clarify;: in Eos, changing the patch for a channel does not delete the show information for that channel: like presets, palettes, groups, cues etc. If you change fixture types, Eos merges the show information onto the new parameters.

  • I just experimented with it. I unpatched a channel and then immediately repatched it exactly the same way it was originally 2 seconds ago. This time it maintained its color palette data but the Augment 3D stuff got reset to factory. The last time I dealt with it was a year ago, so maybe they changed it to maintain the palette data. Last time I had to do it, I had to rerecord basically every palette of my show because the light had zero palette dat after its patch was restored to normal.

  • Maintaining show data after unpatching has been an Eos feature for years.,To clarify: unpatching means, removing or changing the address or type. As long as you do not delete the channel in patch, the show data is preserved. Its possible in the past, that you had deleted the channel with the delete command in patch, and not unpatched it with @ <Enter>  . Deleting a channel in patch removes all show infornation in the show. 

  • During my show, I had a light that was erratically coming on for no apparent reason. I couldn't keep it from rudely turning on in every cue. So during the show, I unpatched it. In patch, I said 32 Unpatch Enter Enter. That solved the problem for that show. No more rude interruptions. After the show, I repatched it the exact same way it was patched before. I stepped through the show and found out that all the data had been erased from the channel. I'm now recreating that and see that when I go to unpatch a channel, Eos prints, "All Non-Intensity show data for these channels will also be deleted, Please Confirm". Of course during the show I probably didn't read that because I was running a show, so I just hit enter again. No, I did not delete the channel. I unpatched the channel to disable the fixture. That deleted all non-intensity data. That's dumb. 

    I later found out that a sub had been left on, so every time I went to a new cue, my manual command to turn the fixture off would be overridden by the sub on the change. I've since learned to go Sub 1 thru thru 1,000 at Out anytime something like that happens. 

  • Parking the channel out or at entering the address would have preserved show data.

  • Ah semantics always causes problems. :) So I was using the term "unpatch" incorrectly - maybe lost in translation. By unpatch, I meant using "@ <ENTER> to remove the Address. I see now that Eos syntax has a command "Unpatch" which removes all channel data (except intensity):


    Thanks! now I learned something for the day. "Unpatch" syntax.

    Regardless, I was referring to just removing the address (or changing fixture type), by using the syntax:

    Ch 1 @ <ENTER>.

    This removes any lighting data output because there is no longer a destination (address), but still retains all show data  for that channel.

  • I have learned something as well, thanks.

    In my personal, subjective opinion, this is a little bit of a dumb quirk. In my opinion, since "unpatch" is a highly visible softkey, the typical user will use that before digging into documentation. Therefore, unpatch should be the least destructive. Deleting a channel intuitively bears the meaning of also deleting data associated with the channel while simply unpatching intuitively is a non-destructive process. However, Eos decides that unpatching a channel should default to having destructive consequences. That can be a lot smarter in my opinion.

  • Maybe that's why "@ <ENTER>" (along with Sneak <ENTER>") are pushed repeatly in trainings. But again and again I am reintroduced to the ultimate truth - RTFM - "Read the fancy manual" .. its 700+ pages, but searching for "unpatch" helped me located the info on page 169 within a minute. Now I wish you a Happy Friday!
