Entering notes in Score Editor, then tweaking position in Key Editor without making score messy

Hello folks
This has always been an awkward thing for me.
I compose orchestral music via mouse in Score Editor. So the score notation, at the point of origin, is all perfectly correct - as a score should be.
But sometimes it is necessary to tweak note positions in Key Editor (due to differences of attack, latency of samples, etc) - but I do not want this tweaking to affect the notated score! Messy!
I could of course play with Display Quantise. But it’s slightly frustrating to enter notes so they are ‘score correct’, tweak in key editor which messes up the notation, then in score editor again apply a display quantise to make them look how they did when initially entered. It’s a shame the notation cannot be visually locked while still allowing ‘non-visually-destructive’ key editor tweaking. But I’ve asked here before and apparently there’s no way around it.
I was just asking an AI about it and it suggested this:

  1. Create a Duplicate Track: Create a second MIDI track that will serve as your duplicate.
  2. Set Up MIDI Sends: On your original MIDI track, go to the Inspector and find the MIDI Sends section. Enable a send and route it to the duplicate MIDI track.
  3. Enable MIDI Thru: Make sure MIDI Thru is enabled on both tracks so that any changes you make on the original track are sent to the duplicate track in real-time.

This way, any edits you make on the original track will be mirrored on the duplicate track. You can then use the duplicate track for your Score Editor layout while freely editing the original in the Key Editor.
When you use MIDI Sends to duplicate the track, any edits you make to the duplicate track in the Key Editor will not affect the original track in the Score Editor. The original track will remain unchanged, preserving its layout and note positions as you continue to compose.

Here’s a quick summary of the steps:

  1. Create a Duplicate Track: Set up a second MIDI track.
  2. Enable MIDI Sends: On the original track, route a MIDI send to the duplicate track.
  3. Edit Freely: Make your edits in the Key Editor on the duplicate track.

This setup allows you to maintain a clean and consistent score layout while having the flexibility to tweak note positions in the Key Editor.

Is there anything to that suggestion or is it just AI going a bit wrong?
If it’s true, I know it’s quite cumbersome, but maybe something worth trying?
What do you think?

Thanks
