I am a big advocate of Ardour. But I really hope they get their act together and stop adding new features, but start making the release more stable. The last really stable and great version for me was the last of the 2.x releases.

They improved the looks but there was always something that didn't work quite right. IN the 3.x series Midi was introduced, but it crashed all the time (and I've updated every time there was a new release).

Now I am using 4.x and it is dog slow for big sessions (which I originally recorded and mixed in 2.x on a much lesser PC with no problems).

I do understand their arguments. I know that they want to release something for Windows, Mac and Linux to improve their customer base (greatly). But I really hope that Ardour solidifies and they start improving the quality that it comes back to the quality of the 2.x releases.
