I'm trying to figure out what it is supposed to offer... All the crap on their page just seems to be "stuff a DAW does". Like they say thing like "Multitrack recording" and "Audio clips". Really, never seen that one before, well except for Cool Edit Pro back in 1998... and every single DAW thereafter.
Maybe it does something amazing, but if so their marketing sucks. They basically just seem to be saying "It's a DAW!" Ya, ok, well I can get lots of those, and for less than $400. The stuff they show looks to maybe compete with the base version of Sonar X3.
My guess is they spent too much time on making a Linux version, not enough time on making it something that would draw people in.
