Maybe it's a bug in the attractmode software because I do have the 32 LED board selected like you show in the pic. I can select 16-32 on the list, and assign buttons to them but it will only show LEDs 1-16 on the screen.
Yeah I think you are right, so to make it work for you:
You need to set the defaults first!I have never had this issue before as when I connected the hardware I set my defaults with that set-up.
But I can understand you want to have a play before you get the hardware.
So I just tried it on two PC without hardware and it does work if you save the defaults first
What does the checkbox next to each Led in the list do?
I'm glad you asked. When the hardware is connected, clicking the checkbox will light the LED. This allows you to see what button is lit so you can assign it accordingly. This is a great feature as when you wire up the LEDS you don't have to worry about what LED number is going into what button as your can assign them however you like later
