You don't need to install it MIDI configuration - Open Stage Control

hi, thanks for your answer! but when I click "list of midi devices" I get this error: A JavaScript error occurred in the main process: Uncaught Exception:
Error: spawn /Library/Frameworks/Python.framework/Versions/3.11/bin EACCES
at Process.ChildProcess._handle.onexit (node:internal/child_process:282:19)

That's why I thought I needed to install

4

You use the built package or you try tu run from sources ?

5

I used the download link on the open stage control site and then followed the steps mentioned in the documentation on the site

6

Make sure the server's midi config doesn't contain something like path=.

9

The midi property is not set correctly. The doc will help you. Does the list midi via the left menu work ?

10

You should also remove what was after path=.

thanks! this did it :slight_smile: I followed a YouTube link where this was mentioned... Touchscreen 2 0 - YouTube

Yeah I guessed that was it but that part is outdated (for the best though as it makes things much simpler :))
