[Invertisment]

My sonic-pi installation doesn't have daemon.rb file. I don't know how to get it for arch.

[Invertisment]

I've managed to start sonic-pi using their GUI and then interact with it via sonic_pi tool.
Could you mention that this requires Sonic Pi LSP server or something like that? It would've saved me some time to know that I can't have it on Arch Linux.

It's also possible that somehow my Sonic Pi version is old. But I have v3.3.1, at least it shows that in UI when I managed to start it eventually.
