These are good programs, however, I would argue that Pure Data is the only one that offers the same or better functionality.

Don't get me wrong, I used to use Ardour and LMMS for everything, Ardour is fantastic for tracking and composing linear stuff.

But Ableton's compositional abilities and creative live performance put it in its own category in comparison - Ardour would be more of a Logic, Cubase, ProTools alternative in my mind. The ability to perform almost collaboratively with internal logic, the simplicity of connecting seemingly any device to a session via an M4L patch- it's just so different.

As I said, I was studying electronic music, and my lecturer was teaching us Ableton, assessing us based on a final recording and the project itself. There's no way I could have abstained from that without a big old zero on my grade- and missing out on some truly great experiences, performances and knowledge picked up on the way.

Sometimes ideology isn't a simple thing, I use FOSS projects as much as possible, even contribute when possible, but I need to work and live on the way.

I would also like to add that Jack circa 2014 was an utter mess, I'm sure it's come on leaps since, but that was always something I felt I fought to get working rather than used. Making the same audio connection in Windows would be automatic, and Jack felt more like a seance.

Anyway, my point is that there's a lot of details and thoughts to people's choices in these things, and if there was one OS and audio workstation for music, it would be a very, very bland thing. :) Anywho, have an excellent night :)
