Hi Brian,
apologies for the later than intended reply.
I wanted to look through our issue tracker to get an idea if these issues are known.
For MA2, I could only find clicking loops in the Mid Strings tremolo patch. This issue is actually on my list to be fixed this week (though as I am not a developer, I can not guarantee as I have no way of knowing how much work it will be).
Please always report any problems you find - we are actively fixing issues all the time and there's a good chance I can send you a fixed instrument for a lot of things. We always collect these fixes to put them in updates, so it is always worth it to reach out!
MA3's releases are on our list, too, though this is much more complicated. As you rightly said, it depends when you release the note. It is easy to actually make things worse there, but we are on it!
I did not find anything about timing issues in MA1. I'll look in our support emails on Monday, but I don't recall anyone ever reaching out about that. Please send me an email with details and I'll have a look!
best
Tobias
