Is There a Limit to MG2 Instances?

Hi, all! Is there a limit to the number of MG2 instances that can be used in a song?

My DAW is Studio One Six, on a Mac Air M2 with 16gb RAM. I’ve been experimenting with using my guitar as a controller for different instruments on different tracks (Plasmonics over here, Kontakt over there, UVI Jazzistic way over there). I’m still getting accustomed to this setup. But I think I’m finding that I can only use MG2 a maximum of 2-4 times before it stops working.

I might be messing it up, of course. Just wondering if there’s an issue I’m not aware of, or if there are tricks to make this work.
