Control Fixture output intensity via midi

[chetan16in]

is there anyway to map Artnet Universe Opacity to control via midi fader?

need to turn off RGB fixture output sometimes so lighting controller can takeover the fixture,
and video will be run from resolume

This is usually done at the point of the merging dmx signals...

You ca send the dmx signals to the light department and they can either pass it through or "ignore" it and send sone other signals they wish.

midi-mapping something inside the advanced output is not possible at the moment

You can't have 2 masters in DMX it's basically a RS422 protocol. So think in terms of old school serial communication. One device drives and other devices listens. If you try to have 2 masters (or senders) at the same time, your slaves (or receivers) will freak out as they are getting 2 separate sources at once.

Send your Resolume DMX info to your lighting console and then inside the lighting console, do a DMX merge. The DMX merge will take your Resolume DMX info (I typically send this on a much higher subnet) and then duplicated that info on a different subnet/universe (Whatever your light's are assigned too), You can then build a macro to turn that merge on or off, or only use certain parts of the info coming from Resolume (Like color for example, when using moving head fixtures).

But you can't have 2 devices driving control at once. You would have to unplug or turn off the one device while the other device is driving, otherwise your lights will freak out.

If your fixture (or Artnet to DMX converter) can do the merging, you could have two senders.
In HTP mode, you could have the lighting console drive pan and tilt, sending 0 on other channels, and Resolume sending 0 on pan and tilt, and sending the colors.
You don't necessarily have to do the merging in the console. But yeah, this only applies to Artnet.

[Arvol]

True.
But you would want to only send the channels you want to change, vs an entire scene pushing out all the channels (especially for moving head fixtures, if you're only wanting to affect the color and not the PTZ/Shutter)

What's sad is that I have some LD's at my company that have been in the industry for over 5 years (doing some decent sized shows) and don't know the difference between HTP and LTP lol
I'm a LTP guy myself

Yes, but with Artnet, and DMX you can only send a whole universe. (well, you can send from the start of the universe, then you can stop at any point, but you can't send only ch30-ch50 for example.)

That's where HTP comes in. I send 0, from Resolume, you send something else to the pan, and your data which is higher will be what's used.

[Arvol]

Yup, Correct

I really wish LX would move away from a 43 year old protocol though lol. Ethernet with a DHCP mode would be amazing. Just plug and play, let the desk do the assigning (Similar to how LED receiving cards can assign once configured). But this is another topic for another time and thread.

Found Some tweak around

Advance Output- Input selection- Create dedicated slice for fixture , place fixtures in that slices ( no overlap to other slices)

Use slice transform effect on layer
add all ur slices including fixture slice

dmx map bypass B for lighting slice

N done..
