MIDI Notes Not Playing?

Hi

It’s my first day of using Cubase 12, and I’ve drawn in a load of chords, but most of the midi notes almost seem disabled, but I can’t figure out how to enable them?

I apologise for this newbie issue. Thanks for any help anyone can give me with this issue. I’m on a Mac and Cubase 12.

Hi and welcome to the forum,

The grey notes are out of the MIDI Part boundaries. Please extend the MIDI Part.
