any ne ideas?
I imported your presets. They do look weird. For example, you have 36 Diatonic presets and 24 QuadroVox presets. All these presets have the FEEDBACK A or PITCH C set at 100. I don't know what happened when you exported the presets but the data looks corrected during that process.
Can you confirm the algorithms in the preset list are same as before? Is that parameter (third one in the second row) only one that has the wrong value?
Also the presets in your pedal should stay same when the pedal was updated. Did you delete them or factory reset your pedal?
