Does anyone know a good house/rave/techno beat maker thats able to play from the computer to your dj speakers cause i wanted to start making my own beats to scratch and mix instead of using other peoples beats.

also free would be nice

Not sure what you're asking.
You want to record what you do on your turn table?
You'd be in the market for new hardware.
I can help you out there. (Yes, you would have to spend money)

nah i got all the wires so i can play songs from the computer to the speakers and the turntables are set up to the same ones i need a beat making program so i can have background music playing when im scratching

Most DJ's I know use a "mixer"
Playing 2-4 turn-tables at once.

But if you just want background beats, I could dig around to find some programs (I have some really nifty little ones, all free) that I could link you to. The downside, it's going to take me atleast a day. (The computer is at a friends house, forgot the names of the programs)

But if you just want to mix beats, theres multiple programs
The most popular around here is "Fruity Loops"
There's also "AcidX" by Sony.

And I'll get on that program tomorrow.

yeah usually i mix 2 but i only have so many records atm so i wanted to kinda make my own beats then eventually make a few songs

Acoustica BeatCraft is good.
