Propellerhead Reason has been the center of my music creation and sound design since version 1.0. I've purchased every upgrade since. Reason 6.5 expands your musical freedom even more. Now with Rack Extensions opening the door for third-party contributors, there's a gazillion more ways to shape, mold, reconstruct, destroy, improve and control your sound and music - all in real-time. Every electronic musical artist should be informed on the power and capabilities Reason has to offer.
