PiSound 1.0 with Raspberry Pi 4 B

My RPi 3B starts fine when I reboot. But I have to wait a little until I can turn it on again, after turning it off

With midi, I use mzeros latest midiminder. Sometimes it takes a few restarts to make it work. It’s just that the signals aren’t received in Pure Data

maybe, I should do this

instead of what I did
