Waves Studio Rack in instruments track Waves v.12 Crashes

Hi everybody,

I updated to Waves v.12 and was using an instrument track. I opened the waves studio rack and it crashed over and over again in Cubase 10.5.20.
When i opened a midi track and access the studio rack from the mixer it works fine. Only when i use a instrument track then it crashes.

Could anyone who has updated from Waves v.11 to v.12 reproduce the problem ?

Thanks for any help you guys could offer.

Windows 10 pro 2004 Intel I5 32gigs of ram
Cubase 10.5.20


Could you provide a DMP file, please?

Hi Martin,

Here’s dmp file.

Hey Martin,

also, it happens when there’s no instruments loaded into the instruments track at all. I did find that if i have a instrument loaded in the instruments track
it does not crash and the waves studio rack opens.

Thanks for any help you can offer!


I can confirm, the crash is in Waves:


Thank you Martin!

Is it because the studio rack Waveshell for V.11 has not been updated to V.12 and that’s the reason it’s causing
conflict ?

Thank you sir! :+1::+1::+1::+1:
