Q Light Controller+

...two separate pages of a frame, or solo frame have a button that is set to receive data from the same external control?

Do both respond, or only the page that's visible?

Only the visible one

In nested frames this seems not to go very well.

I have a large frame with pages.
On the first page I have a solo frame with buttons mapped to 6 buttons on my akai.
On the second page of the larger frame, I have some more buttons, mapped to the same buttons on the akai.
Both pages button feedback is different. when on the first page the buttons are red and when pressed go green.
On the second page, buttons ae yellow and flash while selected.
However, if I press a button on the second page, it will disable the first function and start the second, because it responds on the first page.

Question to you: how would you expect QLC+ to know in which frame you want to do things?
I'm guessing that when you send a feedback to your midi device - it sends it control back to you?
This would explain how buttons in one frame are effected by these in the other frame.
You could disable the frame but the all running functions are disabled also.

Out of curiosity- did you try having one big frame with 2 pages? (Frame 1 and frame 2) and switch pages?

It turned out my problem was only with a solo frame.

My setup is a big frame with pages. Everything works as I want, except for solo frames, but as you answered me that was intended behavior.
