My songs are setup to program my pedals on song selection by sending midi presets through BT. I set my guitar sounds(GT-1000), and my harmony key settings to my vocal processor(VE-500). That works great for me.
I have a specific need to send a midi preset to turn on strobing lights during a specific song. I need to be able to toggle it when its needed. Should I do this independently with a Midi pedal, or is there another viable approach I'm not thinking of...like a button on the layout or some other.
You could add Multiple MIDI Buttons to your layout and click the button for that preset:

Or trigger it with a screen gesture:

Or with a foot switch button:
