Sure. I was on a Lenovo laptop with a limited ram setup (I can dig out the details from all the communication with Brad if you need these), and when I opened Pianoteq in Cantabile there was crackles, if I used Pianoteq as standalone it worked perfectly. Same settings on my Focusrite etc.
In the end, Brad asked me to try resizing the Cantabile window and to minimize it completely, and resizing helped some, minimizing made the problem disappear completely. Then Brad suggsted unticking the GPU checkbox, and that solved the problem. He also spend a lot of time talking to Pianoteq getting this solved, I will have to revisit the old emails to find out what was the outcome, as I was happy with the solution he suggested, and that removed my one concern about buying Cantabile.
Hope this was the kind of information you needed to find out if it relates to your Keyscape issue.
