New Audio Engine: Quick-Start Guide

When I make one Pawn and one Actor who each have their own Modular Synth, and try and run it Unreal crashes.

I am using the same preset bank for both though.

Am I not able to build more than one instance of a Modular synth?

If so, is there a good way for many actors to have their own preset playing from one Modular Synth simultaneously ?

Thanks.
