Why are my copied MIDI clips changing the original clips when I edit them?

This is hard to explain so I'll say what I did step by step and hopefully someone can tell me WTF I am doing wrong.
 
1) I had a percussion/drum MIDI clip feeding AD2 (a tom part that I wanted to and have successfully copied and routed to a DimPro Tympani part)
 
2) I snipped around the part of the original MIDI clip (from the AD2 MIDI track) I want to use to trigger the new instrument (the Dim Pro tympani). I left the original clip in place and perhaps my title is misleading... that section in the AD2 track does NOT seem to be being affected by my edits (only the clip I am about to describe).
 
3) I took that MIDI clip segment and Ctrl + Shift + Dragged it into a take lane in the new target track (the Dim Pro Tympani track).
 
4) Because I wanted to keep the ORIGINAL clip version I just swiped from the AD2 track intact so I could easily revert back I created a new take lane in my DimPro Tympani track then Ctrl + Shift + Dragged the clip from lane T1 into lane T2 (in the tympani track's take lanes... and of course I had to create lane T2 to do this). Basically I created a new lane to house a second version of the clip so I could edit that clip (in lane T2) but leave the ORIGINAL copy in lane T1 so I could easily a/b or revert back as I messed around.
 
Expected result (and this is not a bug report... I think. Most likely pilot error but an annoying one):
 
As I edit the MIDI clip in Take Lane T2 within the PRV (by double clicking it so it opens in the PRV) the MIDI clip in Lane T1 would remain unaltered.
 
What is actually happening:
 
All my edits in the clip in lane T2 are not only taking effect in Lane T1 (like they are linked) when I add notes outside of the boundaries of the T2 Clip (so if the clip ends at 00:02:00 and I put a new note in the PRV at 00:02:05) it does NOT show up in lane T2. It shows up in lane T1... which is muted... and I expected to remain unaltered... which it has not.
 
So to sum up I am clicking on one clip inside one take lane to open it in the PRV expecting to ONLY edit THAT clip in the PRV. I also am expecting that anything ELSE I add to the PRV outside the range of the original clip will appear in THAT lane. I want all other clips to remain unaltered. I just want to work on the clip I have selected in the Track View and NOTHING else.
 
Yes?
 
I am obviously falling down the same rabbithole I have many times before when dealing with MIDI clips/PRV where for whatever reason my input commands and clip selections get grouped together in some weird multi clip mess inside the PRV that I cannot visually see onscreen.
 
I cannot explain this any better and yes I should know what's going on at this point but I've really only been dealing with audio lately.
 
Anyway... I'm just trying to figure this out and yes I am a little frustrated (at the moment) but I know it's my own ignorance. I just would prefer this time of per clip editing would be a little more user frindly for us audio dinosaurs.
 
Cheers and thanks.

aaand just for anyone looking for a possible quickfix to this issue apparently locking the Data on the original clip seems to force new PRV input to populate the selected take lane/clip (as opposed to altering the original clip/lane).
 
I actually recall this being the fix I found MANY moons ago in X1.
 
Anyway... still trying to understand what this behavior means in the grand scheme but yeah... lock the original clip and it'll force new data into the one you selected and opened in PRV.
 
To "Lock" clip "Data" select the clip > Right Click > Clip Lock > Data (there is also an option for Pos that locks where the clip appears on the timeline so it doesn't move when you drag it).

Check your paste special settings quick, do you have linked clips selected? That behavior comes from linked clips via a copy/paste function, but you can unlink them (and make that default paste behavior for future).

Damn... I just shut down but I'll check it out tomorrow.
 
Seems as though that such an option would make BOTH clips reflect the changes outside the original boundaries though (but maybe not). In this scenario any new changes made outside of original clip boundaries populate the original take lane (and clip if close enough otherwise a new clip is created in the original take lane... hard to describe) but not the newer lane/clip I am trying to edit.
 
However aside from that I guess this does seem to be linked clip behavior (as in changes made to one occur in the other). It does not however affect the REAL original clip I yanked the source MIDI from which lives in another track... and after some more futzing about (I kept working) if I drag copy the clips into ANOTHER new track there is no link.
 
It just seems to be occurring in clips within the same MIDI track.
 
Anyway... thanks. I will check that out. Sorry if all that seems chaotic and weird. I really have to get some screen recording software up so people can actually SEE this weird crap I prattle on about. lol
 
Tune is sounding pretty awesome though. I'm quite chuffed.
 
Cheers!
