Oh, I had no idea. It's been a few years since I used it in anger but it was a very pleasant package to use, with an extremely friendly licensing scheme (purchasing a permanent license for <current.X> got you all releases up until version <current+1.max>)

Not to mention it's about as easy to use without a license as WinRAR, so you can trial it indefinitely and then pay the mere $60 for it when you're ready to release some music commercially
