Thanks.

First of all, we strongly recommend that you upgrade Sonic Pi. Version 3.1 is now _very_ old, and is also an incomplete version that only partially works - it was built outside of our control by the RPi foundation. See [https://sonic-pi.net/](https://sonic-pi.net/) or [Releases · sonic-pi-net/sonic-pi · GitHub](https://github.com/sonic-pi-net/sonic-pi/releases) for the latest version.

There are discussions around this here:
