Fast notes with chorus sounds

I'm trying out the new Muse Sounds choruses in MuseScore 4.0.2. They sound beautiful for long held notes, but terrible for runs of short fast notes. They mostly just disappear. I have two questions.

1. Is there some way I can make it play fast notes correctly?
2. Could it be made to play them correctly automatically without the user needing to do anything?

This seems like a case where getting score events rather than MIDI events should allow better default behavior. When it starts playing a note, it already knows how long that note will be held, right? So it should be able to pick an appropriate attack rate automatically.
