In the MS 1 year ago was not implemented the right arrange, the USA developer cant make it working, so we lost about 10 months.A new French developer had made the totally new arranger midi with audio Sync and now is working fine. Before the MS was able to play good the midifiles and Audio stuff.

The MS now is COMPETELY STABLE IF will be used the MS OS UI: arranger, players, sounds...
But for your know, we use Linux and for the VST plugins we depend under Wine. http://www.winehq.com/
This mean that NOT all the VST are working and the VST host can crash, this only because wine cant loading the .dll interface.
So, in this way the MS is still NOT perfect, but this is not our fault and Lionstracs developers can not fix.
All the VST working are listed here: http://ladspavst.linuxaudio.org/
anyway, when you have loaded some VST like the B4 and Kontak2, I think you have enough..

About the MS OS and linux you well that the MS can NEVER have one END, because under PC is possible developing all what we want.
Or next step:
Arranger that will play looped wav files without the sync with the Midi tracks. This mean that you can save in one folder any lenght of wav files and play it in realtime like one DJ sampler, with always the possibility to change the BPM, Timesctrach.

arranger Score/Seq editor midi+audio where you can records by the MS your own styles, without use one external sequencer or Import from the EMC style converter.

X-Kore Linux, the new Lionstracs tool that able you to load and Hyperlink the all the VST plugins instruments under the MS keys and then you can recall all this VST just pressing ONE key.

Multi Score editor, for open the notation from any midi tracks and project in the internal TFT, external monitor or Plasma TV.

Integated in OUR interface Video M-player, where you are able to cue the Video and project the same video where you want.

Do you have understand now why the MS will NEVER completed?
All this new features need time, BUT this do NOT mean that you have to change the MS AND the MS in this right moment is STABLE for play all your stuff.

Let me know if you have understand me.
