I just heard about it.
It's quite new and has great many capabilities, much more than audacity, including midi and other stuff, as well as vst support. It is a shareware so it comes free with no limits whasoever but if you want to support it the non commercial licesense for ordinary humans is 39$ or something like that, while the commercial is 199$ or something.
I toyed with it for 5 minutes and it seems very reasonable, easy to use and flexible. I would be having further tests, but I'm pretty confident already that it's better than audacity!
Go for it I say!
Hmm, this does look good. I can't say I ever used Audacity for anything overly complex but this new program seems very useful.
I'll toy with it in a moment, but even from the website, these guys seem to have a great attitude. Thanks for the link, Nikolas!
