Async mode still not working on VMS

 Hi.What still annoys me is that the Async mode makes no difference for me in VMS. Both have problems with certain MIDI files, such as precision with sound artifacts. It doesn't matter whether it's on or off. With the MIDI player from Falco, if I go to VST, internal player, i.e. without coolsoft midi mapper, it works and I don't have any artifacts. Not with either of them. So on or off. Only slightly audible with XMP play. Could it be the mapper??? Because so far this function is useless in VMS because it doesn't have any effect. At least not in playback. It would be nice if this could be fixed or improved. Greetings
