sometimes I have to insert 3, 4 times for the pedal to read the sd card, I have 2 sd cards and the same thing happens with both
It’s possible that either the contacts on your SD card are dirty or that the contacts in the pedal’s card reader are dirty.
Use a pencil eraser to gently clean the contacts on both SD cards. As far as trying to clean the contacts on your pedal’s card reader, try using canned compressed air. Insert the nozzle and give it a couple of short blasts. You can try DeoxIT contact cleaner to see if that helps. You can find it on Amazon or any electronics store.
