In Logic 10.6.3 I have this running great on my M1 MacMini but I don't see anyway to use automation to switch between in articulations.
How do I do this?
I believe you just have to make separate tracks per articulation
I wrote an answer yesterday but it seems disabled. By default your key switches are at the very bottom, starting with C0 and up to how many articulations you have for that specific instrument. You can see them highlighted in green when you go -2 or something on the piano roll, with that up and down arrows, and you can drag them up.
Go to the bottom-left side of your 2 modwheel and piano roll, where there is a 0 with up and down arrows. Click on the one down a few times until you see the green highlighted keys, which will be your trigger keys switches in your midi. It's usually the very bottom ones, C0 and the ones following. You can also modify them.
@gabegarza let me know if the video @George-Ciprian provided above helps!
