I've take parts from a few your patches and combined to make this:
What I need my patch to do, is to be able to sync a flash/strobe effect with the bpm of a song, which will be tapped in through the button labelled Tap.
This patch does achieve this at the moment, but only half the time as it's only every second tap that creates the flash, and I need it to flash on every beat/tap. I think this is something to do with setall turning the flashes on and then off?
Any help will be massively appreciated! Thank you!
