I don’t know if somebody has posted something about it, but anyway here it goes.
BeatBuddy user for 5+ years and successfully playing live with it every week in an outdoor venue since October 2020, yesterday at a party the BB started showing constantly the Volume % in the screen. Also, the volume didn’t go below 7% and neither beyond 87%. Very odd. The first time.
I thought at first it was the Firmware or the Card, but it wasn’t because I took the card out and the error kept showing on the screen.
So, I opened the BB and used an air duster cleaner for a couple of minutes.
Voila! It worked.
So, I hope this helps for somebody out there.
