Old Dre beats do have alot of the synth and synthbass things going on! Though in my opinion p-funk is all about bpm's! its the "inbetween" funk! I'm listening to "greatdayindamonin" rightnow and it also has this...indescribeble feel to it because of this bass sound i'm diggin'!!! allthough the booklet says it is charlie hunter is sure sounds like one of those old analog moog synths! (this is a track on voodoo, which I know is not your fav...but I'm just talking synthwise!) Also a track which I hear Dre's inspiration is "flashlight" strings, synthbass and all the other bleeps going on! I'm still a student of funk though...
It doesn't have to be difficult funk http://www.youtube.com/watch?v=Qpl17Uqs7Bs I'd like to hear D sing over a beat like this!
