I installed this patch. It’s so much fun!

This issue happens because Organelle OS v4 uses Pure Data version 0.49, whereas OS v5 runs Pure Data 0.53.

Upgrading Pure Data to version 0.53 or higher should fix the problem.

For instructions on how to update Pure Data, please refer to [this thread](https://forum.critterandguitari.com/t/update-to-organelles-version-of-pure-data/9821/11).

While it might work on OS v4.1, it’s probably best to update to OS v4.2 first. You can check [the official documentation](https://docs.critterandguitari.com/Organelle/og_sms2/#71-burning-sd-card-disk-image) for steps on installing Organelle OS v4.2.

Hope this helps, give it a try!
