Try loading BS-16i with a smaller size sound font. The problem is likely due to the fact that the app does not disk stream, so the whole soundfont needs to be loaded in ram.
Also this AU is known for not working well when several instances are running simultaneously. I have only been able to get 1 AU instance running at a time.

I can test a bit later.

I've definitely had recent tracks with at least 2 instances of this running fine (iOS 11 iPad pro 10.5).
But I haven't used it since upgrading to iOS 12 list weekend so will try to remember to test this again for you later this evening.
