Just to clarify how the dot9 series pedals work, a program change command from a controller is a 1:1 function meaning PC1 equals preset 1, PC2 equals preset 2, PC3 gets you preset 3, and so forth. Since there is no way to change this mapping on the pedal side, incongruent mappings such as you’re experiencing @mnkristof leads me to believe that something may not be programmed correctly on the MIDI controller side.
