rtmidi-python won't work with Python3.10+

The following error occurs when running: pip3 install -r ./requirements.txt

This is where is went looking for an explanation: https://stackoverflow.com/questions/71410788/pip-failed-building-wheel-for-rtmidi-python-subprocess-exited-with-error-and-le

Here's a link to the old library. https://pypi.org/project/rtmidi-python/#history

Link to another: https://pypi.org/project/python-rtmidi/

I may add more notes or see if I can fix this since I really enjoy using the editor.

The problem is with python 3.10 The library doesn't support it.

I'm running Ubuntu Studio 22.04

Installing this library seems to fix the problem. sudo apt-get install python3-rtmidi

Hello, thanks for the report!

I tried uninstalling the python-rtmidi from apt and installing the one from pip, and it works on my end. The old library you linked to seems to be rtmidi-python, but the one we use is python-rtmidi, so I don’t think that issue is related to yours.

Sorry I have no what went wrong, but I’m glad you could make it work :)

Leaving this issue open if anyone encounters the same issue.
