(Solved) MIDI Editor Quantize Multiple Items Problem

Scenario: Let's say I record a MIDI kick drum on track 1 and a MIDI snare drum on track 2. The timing on both is a bit sloppy. So, I select both recorded items and double-click on one of them to open the MIDI editor. The MIDI events from both selected items appear, but when I quantize, only the events from the actual item I double clicked on are affected (See attached image). Question: Is there a way of opening the MIDI editor for both selected items where both item's events are active?

Make sure you have the track list shown in the MIDI editor. Then, highlight all tracks in the track list you wanna work on simultaneously. Finally, select all events/notes across MIDI tracks in the editor that should be affected and do the editing. .

Attempt 1 Failed 

SonicAxiom: I did what you said . but I was still unable to select all notes with either Ctrl+A or right click and drag. Am I missing something?

Attempt 2 Failed 

smandrap: Either pressing Q or clicking on Q brings up the same window. I have tried changing the options, but nothing allows me to select the other item's events. Is there another Quantize window that I'm not aware of?

Can you screenshot your Preferences > Midi Editor page? Set it like this:

smandrap: I changed a couple of settings based on your image (See attached image) and that has got it working for me. Thank you so much for your help and support. Thanks to SonicAxiom too.
