In this photo I have a midi controller that uses keys instead of sliders and knobs. I like using a keyboard when I'm running applications like Arkaos. Having keys to trigger clips or trigger the live camera feed is a nice way to keep sync with the music from an external source. I usually run a firewire cable from the Edirol PR-80 straight into my laptop running Arkaos, then I create various comps. in the program and trigger the live feed via the keyboard. There are just enough knobs to control the various CC# variables in Arkaos.
