Well… after a quick test, what is the new thing about the Instrument Tracks ?? Nothing. I will never work with this ever. Look at this picture :
The first channel has the three outputs attached to it while it should only have the one it is linked to, in this case the first one. Then when you add the second midi track it doesn’t name itself Omnisphere 02 but Midi 01 which is absurd. And it doesn’t nest with the previous group as it should be, it’s just a midi track…
Never understood the instruments tracks…
