I've been using lmms for over a year now I love the intuitive interface, sounds good,  easy to install.
  I wish it had an audio capture funtion with an input meter with a basic editor just to trim up audio samples.  I believe this would really complete lmms as a DAW.  LMMS is so much more end user friendly and better for sequencing percusion.
  Rosegarden can only record with jack, to edit audio samples you can select a default editor like rezound, which is great for editing start, stop and loop points.  This all works fairly well, but I sometimes wonder if a program could do all of this independent of jack,  could it remove a complicated xrunning link of music production chain.
  I've been using the virtual keyboard to play the triple osc with my computer keyboard, fun.
 
All the best,
Scott
