desk chanels and dimmers

I dont quite understand what you mean... Could you elaborate a little?

Best,

Use the UnPatch @ button in the patch window

Unpatch @ "DMX/ Dimmer"

From the User Manual section 14.2.6:

To unpatch a specific DMX start address you need to change the Fixture window to
View by DP.:
1. Setup → Patch : open the Fixture window.
2. View by DP : change the Fixture window to View by DP.
When View by DP is selected, the UnpatchAt button is available on the top toolbar of
the Fixture window. To unpatch start address 200 in the currently selected DMX universe
(highlighted in blue):
• UnpatchAt 200

thank you so much that is very helpful.
