Crap. Thanks for the quick reply nevertheless!
This leads me to a second question; if I, for instance, want to use the beat from an instrument to flash a armature, how do I do this? The way I see it, you plug the audio into the desk and make a chase with bass as drive. But then, the armature won't flash, it will simply stay alight until a new beat comes and then it will switch off. So it will take two beats to make it flash. Perhaps you can fix this by using an echo-effect or something similar, but still, it would be easier to do it with the desk. (Anyway, in my case it will be)
Any ideas?
