Polyphony set at 'Automatic (optimistic)' or 64 makes no difference. It does not seem to be strictly depending on any possible overload coming from my midi-feedback system since Pianoteq is constantly demonstrating itself to be able to hold huge amounts of both midi notes and change-parameter events at once with my system.

The fatal error may just occur at some random point in the middle of a live session, be that in 2 minutes just as well as 2 hours. So I would really appreciate some help and guidance in troubleshooting (hopefully fixing).

Could it be related to Pianoteq's undo history or the like? Does anything similar happens only to me?

I will provide more details if needed, of course. Looking forward for someone in-the-know to letting me know. Thanks!
