I also had a crash: With Pianoteq 8.2 and ASIO4ALL V2 2.15 the application freezed after start at once.
I succeeded in uninstalling the ASIO4ALL driver (there is an uninstall exe in the program directory) and installing verision 2.14. Then everything worked. 2.14 can be downloaded from the official ASIO4ALL website.
Give it a try...

I uninstall 2.15 and reinstall 2.14, THAT WORKS.
Thanks a lot !

Never had this issue.

However the onboard realtek never sounded that great to me, so I'm using an external focusrite interface.

I would suggest, if you haven't already.

Latest motherboard bios
AMD just released new chipset drivers
Latest realtek driver
EXPO settings for ram
If you are using PBO, turn it off and try again

And Oh yes :-) that's a real slow CPU you have. I'll swap it for my 7700 to help you. Anything for a fellow Pianoteq user.

Yeah, I'm up to date with all the drivers, EXPO is on, no PBO -- I guess things just happen sometimes. I played around with some settings and haven't had a crash since, although I would have preferred to keep the buffer size smaller...

Well I guess even a 7950X can't feed Pianoteq with those juicy CPU cycles fast enough I really should replace it with a celeron...

Before the dialog box appeared, I heard a pop and then white noise that started increasing in volume. Then dialog box, and after closing it Pianoteq closed as well. I wasn't pressing any keys on my MIDI keyboard.
