Okay click this link: http://www.image-line.com/documents/flstudio.html
and download the demo version of fl studio 10. :)
You can buy the full version but it's a little expensive. I myself am planning on getting the Producer edition download which is 200 bucks. Fl studio 10 comes in 4 editions each a little more professional from the other. Honestly using fl studio is a little confusing at first but just start exploring and clicking things and you'll get the hang of it. It will be a piece of cake.
I warn you though while using the Demo certain pluggins and programs your using on it will have a short silence to remind you your using the demo. This can get quite annoying when trying to create. TRUST ME but try your best and consider getting the full version as soon as you can. Also another thing to be aware of, the demo version does allow you to save your work but the only downside is you can't open it back up until you buy the full version. PAIN IN THE NECK i know lol. I'm pretty sure that is all. I've been using fl studio for a while now and it is by far the best i've ever used.
I use it for my band "Technicolor Blood Flow". I've gotten alot of positive feedback so far from friends and others. I wish you the best as well.
Here's some of what i've done. Remember i did all this with ONLY the demo version and every ounce of strength in my body haha.
Just a few
