Hi Kai, sound variations for the VSL Syncron player in Studio One only work with :-
VST 2 version of the Syncron Player ( it will not work with VST 3 or AU versions)
Need to be running Rosetta version of S1
Hopefully VSL developers are working on an AU version of the syncron player that can utilise both sound variations and enabling us to run S1 in native ( silicon ) mode.
