If you are a macOS BeatBuddy user and you are getting an INVALID SD CARD error on your pedal, you can try the process in this thread.
I made an image file of a freshly downloaded BeatBuddy Default Content 2.1 - Project contents and have written instructions on how to recover.
Whether you are successful or not, please let me know. If you were able to restore your pedal by other means, please tell the forum what you did as I’m sure other users will benefit from your experience.
