Hello,
I’m having the identical issue with my 22500.
I’ve upgraded the firmware (28) several times, I even went out and purchased a brand new sd card, it has made no difference.
I’ve reformatted the card several times and copied the drum tracks over.
The drum track will play fine, but the very second I tap any A/B/STOP switch, or touch any of the reverse/octave buttons, the whole looper freezes up and doesn’t respond.
Did anyone get this issue resolved?
Am I doing something wrong?
I’d appreciate any kind of response.
I’m pretty choked, it’s a great pedal wasn’t cheap.
