Ahh, I’ve done something which I believe links midi clips, but just cannot figure out how to change it …
I had a midi clip in one track I wanted to copy and drag to another drag. I did shft + alt and this seemed to work.
I then edited one of the clips - deleted some notes and it deleted some notes from the other clip also.
I see each clip has 2 small white lines in top right of the clip - I guess that means linking — how can I copy without linking, and how can I unlink them - I tried the manual and a forum search but couldn’t find anything, though I guess it must be easy
