How to create a breathing/pulsing constantly fading in/out function?

Hi, having trouble creating a function that creates the effect I want. The kicker is that it needs to be time synced to a speed dial that I have that receives MIDI in order for my show to be beat synced.
What I want is to have a function that makes a light fade in then out then in then out repeatedly in time with a multiple of the speed dial setting. So it's slowly repeatedly pulsing on and off.
I've tried using a chaser but I can't quite get it right. Setting the speed dial fade in, out, and duration factors for that chaser seems promising but it sets them for all items in the chaser.
I think this is possible but I'm not seeing it!

Use the EFX in dimmer mode. If all lights have to 'breath in sync' use a width of zero and a phase of zero.

Hey thanks for the suggestion. I actually hadn't looked much at EFX functions since I assumed they were just for moving fixtures. But I see this could be a solution.
Only problem is that I can't set it to dimmer mode for my fixtures (which are RGB LEDs). The only option is RGB mode. It does make a nice color change though!
How can it be set to Dimmer mode?

An other option could be to use RGB matrix with pattern = "Strobe" and Control Mode = "Default RGB". In your Speed Dial set the duration to 0 (zero), only use Fade In and Fade Out.
The challenge is to find the right values for your Fade In and Fade Out times.

Super cool idea thank you. Tried it out and it's close but for some reason it doesn't quite stay on time and drifts after a few cycles. Not sure why. I have the speed dial set for factor 1 for fade in and out, and "not sent" for hold.
I'm using QLC 4 BTW. I don't have a "Control Mode" setting so thought that might be a v5 thing.

Instead of "not sent" you could set it to zero, to make sure that it only fades.
The Control Mode is (even in QLC 4) one of the parameters of the RGB Matrix (it is just underneath pattern).
If you only use RGB Led's however you can only use the Default (RGB) mode.

Thanks yeah it’s funny, when the duration is set to 0 nothing happens. I have to set it to “not sent” and then set the hold time to 1ms to get it to do anything.
Also I have just “blend mode”. Default (HTP) etc
