I have now received a Raspberry Pi4 8gb running at 1.8gH.
Both BIAB 64 bit and 32 bit open and run.
Forget using real tracks as the Microsoft emulation swamps the little machine and sound output crawls!
Track building from Real tracks takes about 30 secs to a minute.
Midi only with Real drums is about as fast as my Asus i5 laptop.
Connection to my Yamaha DGX is instant with no lag.
Rerouting output through a virtual synth works very well.
As a midi only setup using an external midi device or using a vst the Pi is incredibly small and is up to the job.

I have a developers version of Windows for ARM64 and testing some applications which are already available to run in native ARM code. Receiving almost daily updates from Microsoft.

My laptop has been updated to Windows 11 with no bugs found yet.
