See title 🙂 Seriously, alt-mouse-scroll in the PRV Note Pane will zoom in and out. Handy. However, doing the same on the Drum Grid doesn't. This is annoying. Please consider applying the same fix as you did to the Note Pane some time back to allow Alt-Mouse Scroll behavior. Thanks, rock on EDIT: Confirmed bug/deficiency was addressed in the 2021.06 release.
