More on Raspberry Pi testing -

Pi OS desktop loaded Ram usage 138mB out of about 3mB available.
Pi Windows 11 Arm64 desktop loaded Ram usage over 2gB.

I would wait for a Pi500 or whatever they call it with 8gB Ram.
Pi4B with 8gB ram has been produced but stocks are unavailable here in Australia until well into 2022.

LMMS (DAW for Linux) works incredibly well on PiOS with only 175mB used when run. Loading a GM soft synth and midi file brings Ram usage up to 405mB in total.

LMMS can use the built in HDMI sound output but Win 11 ARM64 using PG music products cannot. I have ordered a USB sound card output and suspect this will work. I will then test BIAB real track output.
Pi400 has no audio jack but the Pi4 has.
