A beatmaking software ( previously called fruity loops ), by Image Line.
I use FL Studio to make my beats!
A very stable piece of audio production software. Though stable, it unfortunatly is designed by Digidesign, the biggest bastards in the industry. They require you to use exclusively their hardware in conjuction with the software. When the new version of protools comes out, all the sudden you have to buy new hardware because its not compatible with the new version... even though Digidesign themselfs designed and sold the hardware to you only two years earlier. Their hardware is high quality... and you pay for it. An entry level Protools TDM system costs upwards of 10 grand. Isn't it nice to know that those thousands of dollars of hardware will be useless in two years? Protools doesn't play nicely with other pieces of software. Your computer must be free of all other sofware for Protools to work. If by any chance (which is great) that you will need tech support, Digidesign will be glad to take your $60/hour to tell you that the reason your system doesnt work is because YOU fucked it up, even though its clearly bullshit... Every professional in the industry should stock up on MOTU I/O's and nice mic pre and just use Nuendo. It may be slightly less stable, but it can do more and your hardware will last you many years with multiple versions of software.
I wasted $30 grand two years ago on a system thats now worth 2 grand. I should have spend a quarter of that money on a Nuendo system that still would be useable today... even with the new, more stable version. With the extra money I could have bought a rack of high end Focusrite mic pre's to make extemely prestine recordings.
