REAPER 0.996 is out and that means v1.0 should be just around the corner. The updates keep coming with amazing frequency. I spent some more time with it today to get in some last minute feedback and it's still a really impressive piece of software. Check out some of the features here. It's incredibly functional and customizable and the entire install is still only one meg in size. Once again it's free up until v1.0 and then according to Justin's post in the forums:
Should be something like $40 for noncommercial use and ~$200 for commercial use. Purchasing 1.0 will give you a license for all 1.x releases..
And after being asked how they'll define "commercial use" he posted this clarification:
as far as what constitutes commercial use, it's essentially if you are a) making money directly from what you're doing, or b) using it in a workplace.We will let you upgrade from the non-commercial license to a commercial license for the difference in price, as well. so if you go purchase the non-commercial version ,make some stuff, then end up making money on it, you can pay $160 or whatnot and be legit.
The important thing about all of this, too, is that we won't take any technological steps to enforce this-- it will be up to you to do the right thing. If you don't feel you're doing something commercially, then you're probably not, etc.
