SetBusVolume throws ArgumenOutOfRangeExceptions

Hi All,

We have a sound that has Weight(Instances) : 8

The debug shows it can find i=0 but it cannot find i = 1 to 7



private static void SetBusVolume(GroupBus bus, float newVolume) {



try {

aVar = aGroup._group.groupVariations;

aVar.SetGroupVolume = grpVol;

}

catch( ArgumentOutOfRangeException ) {

Debug.Log( String.Format( "aGroup:{0} aInfo:{1} aSource:{2} i:{3}", aGroup, aInfo, aSource, i ) );
