hey, in my house we have one of those old console organs from the 70s, and this one is a Wurlitzer with an "Orbit III" synthesizer on it.. it has two modulator knobs which are labeled "deviation" and "repitition rate".. does anyone on here know what i am talking about? there are nine sine wave buttons too... what can i do with this? http://www.mp3.com/jasonzastrow
