hello! I'm new here and hoping someone is able to guide me in the right direction - I searched the forum but couldn't find anything on this topic
I'm trying to figure out how to display the tempo of the speed dial to an led via GPIO pins
is this possible?
thanks!

Welcome to the forum,
Yes you can
create a dimmer in the GPIO output universe - look at the provided .pdf for the pin assignment.
You have to configure the GPIO as output.
I would suggest you create 2 scenes: 1 with this dimmer @255 and 1 with this dimmer at 0
Create a chaser and add these scenes.
Set the duration to common and give it a value: 250ms equals 120 bpm
Verify that the chaser sends signals to the GPIO output. (be aware that you need a resistor in your circuit between V+ and the GPIO output and your led ... search for the circuitry)
If this works, you can change the properties of the speed dial, so that it sends its signals to the chaser you created.
Now your led should light up in pace with the tempo set.

I have a small LED with a 100ohm resistor (+) plugged into PIN 32 (GPIO.12) and (-) GND
I have created a dimmer in the GPIO universe
it is addressed "13" to correspond to GPIO.12 (PIN 32)
in the Inputs/Outputs section I have GPIO lines Output enabled
GPIO.12 set to Output
in the simple desk on channel 13 the fader at 0 the LED is on and when I slide it to 255 it turns off
the scenes I created (one at 0/one at 255) do nothing though
am I missing some backend raspberry pi thing?
I am using the paid for qlc+ rasp pi package
I was able to figure out how to make gpio connected footswitches work as inputs and can make lights turn on through my other dimmer universe connected via enttec open dmx usb
aaaaa
thanks if anyone can help!

You need to understand that the Simple Desk overrides all other functions.
If the slider of your channel 13 is red, press the Reset Button underneath it.
Now check your scenes again.
