The possibilities this software gives are huge and I'd love to have more time to enhance this show.
I use the headphones output of the dj's audio device as a microphone input in my laptop (just changing the realtek settings to read the minijack output as an input). That's not the best option, but allows me to control the amount of signal/reactivity of each visual. I'm considering changing this to a global controlled by a midi slider.
I use an apc mini midi device to control each scene and some fx.
Visuals were projected over a DCP projector
Hope you like it!!
