+//   # Mini Song Switcher
+//    ## Description
+//      The mschnell_Song Switcher is inspired by the cfillion_Song Switcher.
+//      It is a lot less versatile and only features a single script and no GUI
+//      Other than the cfillion_Song Switcher is does not work on the foreground Project (Tab) but on the first project (Tab) that holds a project with the string _song_ in it's name.
+//      If such is not found, it works on the foreground poject (Tab). Don't forget to enable  all three background project playing options !
+//      It uses the same track structure as the cfillion_Song Switcher (Description see there)
+//      When a CC action is received it unmutes the track named according to the CC value (e.g. 1. XYZ or 23. Hello)
+//      It then start playback (from the location pf the play cursor) 
+//      When a value of 0 is found or no appropriate track is fond the playback is stopped.
