Looks like the CSV file in the SONGS folder got corrupted. I only have one entry ’ 1. New Folder’. If I manually rebuild the CSV contents from the entries in the folder, will the HASH.BCF rebuild itself?
Most likely not as the BeatBuddy Manager (BBM) manages the songs, folders and drum sets. If you’ve been “tinkering under the hood” of the software, that could be one possible cause for the symptom. The other possible cause could be the naming of a song using special characters. For example, if you named a song using a period, “1. Mrs Robinson” or “Mrs. Robinson”, the songs will disappear from your BBM. Yes, the csv file will also appear as you described.
How to recover? If you saved your project to your SD card, and the songs are all there, you could use the BBM File > Open Project and navigate to the project on your SD card and then save it when prompted to your bbworkspace.
If that doesn’t work, you will most likely have to use the General Disaster Recovery instructions available here on the forum.
