Very good for building up from decent melodic dalay to total reverse chaos and then leave the reverb hanging there... Footswitch 2 switches to the "Reverse Chaos Section" and on Button 2 is the CHAOS control which is basicly the Wet controll of the Reflector. I recomend to use an Expression Pedal for the CHAOS, but for you i put it on button two, which I also used on the audio sample by turning it with my toe. The sample, by the way, doesn't really reflect the spectrum of building up something but I tried my best to get some idea of it in one minute :/ Have fun! ;)
