I can’t even tell what window you have open. If it’s the key editor then…

I’m guessing the show/hide zones (located in upper right corner assuming you have it opened in the tool bar set-up) would open/close this.

There doesn’t seem to be a way to widen this area - odd

Yeas that what i need. i want to wide the area

Ok. Key editor controller events.

I agree. Same with the Drum editor. Has it ever been adjustable in prior versions?
