I'm using Freestyler in a small youth club, during normal business hours there are just 6 led pars reacting to our music. If there's a party we switch on two scanners (JB-systems The Winner II) and a strobe.
This is working fine, but our less technical volunteers (read: girls

Button 1: Black-out
Button 2: Sound To Light (on/off)
Button 3: All led pars white
Button 4: strobe flashes (when pressed)
Fader 1: General light intensity
Fader 2: Speed led pars
Fader 3: Speed strobe
But unfortunately I couldn't find a way to turn the Sound2Light plugin on/off.
Cheers,
Dieter
btw Raphael, our youth club is in your neighborhood (Terhagen, www.tsoot.be). It would be a pleasure to welcome you.
