Here is a thread where some of us got latest mod software running on our patchbox .
In my case I use raspberry os 64bit latest , Just added pi-sound btn and services manually into my installation and I got a kind of “Patchbox” experience without some of the advantages .
I would be thrilled if someone with more knowledge goes ahead and tries to create an image with 64bit/rolling stuff going . I would test it out, since I did not have the courage to continue trying and ended just on raspberry OS
