A linux alternative to Sonys' SonicStage.

http://symphonic.sourceforge.net/

Installation:
Download and unpack the zip file (not the source).  And create a launcher.
ie.  I unzipped mine to /usr/local/bin.  The local user will need write permissions in this directory as an xml config file will be created when you first run.  Then create a launcher in ~/.local/share/applications/

$ cat .local/share/applications/SonicStage.desktop
