Pianoverse Buffer Problem

[isikaka]

hello evernyone, i've just bought Pianoverse but after playing a few notes or chords each time , no longer will be any notes to hear.. I've never had any issue with other plugins like this..
Midi trigger does work , even you can trigger with mouse definetly.. but aint no sound at all..

I've tried different buffer and resolution options..

My setup is: Imac 2020 inteli9 ssd drive / SONOMA 14.6.1
Apollo twin X for mac.

Any idea pls?
