Shortly...

Just installed Aion for adding some new stuffs and found some changes in scripts system, on any event in OnSoundPlay function game sending label == 0, but before it's was nil. As result all multi instrumental scripts dont work as expected. Would be fixed soon (not today, time went to sleep for me atm). Ok, new version of MusPlayer was added, but all multiinstrumental scripts (which was created before) would works incorrect anyway... You can fix them by changing text in scripts for musplayer:
"[0]" to "[1]"
"[1]" to "[2]"
"[2]" to "[3]"
"[3]" to "[4]"
"[4]" to "[5]"
NotesConvertor will be updated later (found few bugs in generator for standalone scripts).fixed
