Reply to Wobble sound with simpler in ableton.

I have goten a good wobble, and played with it... However the wobble sounds seem to build through a progression. From quiet all the way through loud then sometimes the pitch changes on its own, then it comes to an abrupt stop. I want to make a consistant sound so I can record a clip that actually goes with my drums. Dose anyone have any good beginer advice or tutorials?

Also a random side question on my dj set up, im having trouble picking a mixer, I need a 4 channle, im using 2 techs and a oxygen 8 + foot pedal. Im not worried about on board sound cards ill get an audio 8 if I need too but either way but I want to use traktor. im on a budget but Id go for the best product possible. The xone db4 looks good, and I li,e the rane because I scratch and I like their faders.... Ahh please ne feedback from people whove had a chance to use theese mixers that are turntablists! I know those examples aren't budget mixers but they represent what I want. Ive been believeing pioneer djm 700 plus audio 8.
