You may be better off building ffrom source and not worrying about
jack support then... I use Rosegarden just for composition/MIDI and
use ardour for audio tasks.  I came from the Windows world of audio
also (but have been using Linux otherwise since 1995), it's a bit of a
painful leap at first, but well worth it.

Do newbie instructions for building from source files, without jack support, exist somewhere? Or can you give guidance? I have been using Audacity for audio tasks, but I will take a look at ardour. Do you know if they do basically the same things?

Thanks so much for your assistance!
