Does anybody know how to use 4 or 5 virtual instrument plugins without creating a loud white noise and after opening BIAB does not make any sounds.

I am using a MIDI style and I wanted to improve the String1 and String2 sounds with sounds from Cinematic Studio Strings (via KONTAKT 6) and a beautiful string patch from Ominisphere for String2. I also had added a Piano sound from the plugin Keyscape. I also had a plugin for improved piano on the THRU track.

My Windows 10 64-bit computer has 96GB of RAM and 2 processors and about 32 threads (16 threads per CPU).

I am using a Focusrite Clarett 8Pre-USB and am using the Focusrite ASIO in BIAB. I have BIAB Audiophile Edition for 2021

Any suggestions or fixes?
