I am currently working on the issues detected by Bodyia. This allows me to address another phenomenon, on which, at first glance, I can't do anything within The Pool. ;)
For my tests and diagnostics, I use an Arturia Audiofuse 16RIG sound card, which works quite well for me. It has a USB-C connection to my PC. On another USB port of the PC, I have the connection with The Pool, which allows me to download firmware to test updates. The noise generated by this dual connection is significant and misleading. However, if I disconnect one of the connections, I notice the immediate disappearance of a random, non-clocked noise originating internally in The Pool.
If I use the same USB port for the PC-Audiofuse and PC-The Pool connections by using a smart USB-C hub (Ethernet, Display Port, etc.), there is no more noise.
So, when running tests, please make sure to carefully check the context and conditions to reproduce the issue.
