To the people that posted before me: if you read through the whole post, you would see he wants something similar to the programs FL Studio and Reason.
Now, finding something like those is going to be really hard. FL and Reason are both top-quality DAW's that have had a lot of work put into them, and find a free program similar to them just might be impossible. There is Reaper, which is a non-crippling software you can buy for $50, and has VSTi support, a MIDI interface and some tracks to put that in and such, but I seriously doubt that you will find anything with the functionality to FL and Reason. I'd suggest saving up your money and getting the second cheapest version (I can't remember what one it is, but it's after the download-only version for 50$) if you really want to start making some awesome stuff.
