[zver43]

Hi.
I’ve just bought update Cubase 10.5.12

1. And where is Event Opacity in preferences ?? Its helps me to make transparent events in cubase 10. (see attachments)
   Only with transparent events i can fast and well make editing.
   But now i’m really disappointed with you
   Please Fix it!
