Disclaimer:
This is not a finished version of the program, it's an Alpha, not a Beta version yet. There will be lots of problems and bugs and it may not be compatible with the final version at all. A lot of things haven't been changed yet. If you don't think you can handle this, please don't install this Alpha version and wait for the FL Studio 12 Betas or the release version of FL Studio 12.
