razer black widow ultimate (2014) rgb issues!

Earlier this morning I got a razer black widow ultimate the first gen version so no buttons or dials. I got it for only 15 dollars and it was in pretty decent condition, the only problem I'm finding with this 100% keyboard is the rgb, the razer software I have to use is named razer configurator and I can only change the the brightness and whether or not I want the rgb pulsating. when I go inro razer synapse it wont recognize the keyboard and says legacy devices and when I hover over it it says “this device needs Synapse 2.0: Razer BlackWidow Ultimate”. Does anyone know if this is the only rgb I can get because its such an old keyboard or if I can use a different software and change it?
