>However you're giving up a lot of third party instrument and effect options, aren't you?
You'd be surprised just how many VST's work smoothly and reliably under Linux.
>Bitwig
Tried it, but not a fan - I have too many external hardware sequencers to be bothered with setting it up with the rest of my system. (Hardware sequencers run forever!) I do, however, have Ardour set up for perfect multi-channel recording, so every instrument has its own digital tracking, and this has been wonderful ..
A few years back Linux Voice reviewed Bitwig and they seemed to like it a lot:

As plugins go, many good ones are available in LV2 or similar formats so no problem on that front.
And have you tried Bitwig yet? With its similarities to Ableton Live, I'm sure it has the potential to push audio production on Linux to some degree.
