Hi everyone,

I’m encountering a persistent issue with Isadora 3.2.6 on macOS Monterey:
The MIDI port configuration is not saved after restarting the computer — even when using stable virtual ports like IAC.

Here’s the full setup:

• macOS Monterey

• USB MIDI controller (direct connection or via unpowered USB hub)

• Also tested with macOS IAC virtual ports (enabled in Audio MIDI Setup)

• Preferences file:
  ~/Library/Preferences/Isadora Prefs 3.2.6.izp

• File path verified, correct read/write permissions

• Isadora is properly closed via Isadora > Quit Isadora

• After relaunching Isadora, the MIDI port is reset to "None" in Communications > MIDI Setup

This issue occurs even when using the IAC ports, which are supposed to have stable names and identifiers across sessions.

Questions:

• Is this a known limitation in Isadora?

• Are there any recommendations or workarounds to ensure that the MIDI port configuration is retained across reboots?

• Could there be a hidden preference or a fix in a newer version?

Thank you very much for your insights and support!

Best regards,
Benoît
