This is probably a noob question, but after some searching, here is an example of my problem:
When I click on the flute part at measure 24, the trumpet part a few tracks up at measure 24 also becomes selected. Same is true in reverse. If I ctrl+click just one part to deselect it, they both become deselected. If I move one, the other also moves. If I delete one, the other is also deleted. If I double click on either, they open up together in the piano roll with one instrument’s notes bright in the foreground, and the other instrument’s notes desaturated in the background. These are all midi tracks I’m dealing with, linked to VSTs, and I’m on Cubase 6, the full edition.
The parts were recorded separately, and are on separate VSTs (one may be on Kontakt, and another Play). This happens throughout my piece seemingly with no rhyme or reason, sometimes with a good number of concurrent parts becoming linked together, always at the same measure, but on different instrument tracks. Once stuck together, always stuck together. Tried saving as a new file, but no luck.
How did the separate parts become linked? How do I unlink them? What the heck am I doing wrong?
