COBALT8 supports both types of sustain pedal polarities when connected via the sustain pedal input port.
“Positive / Normally Open” pedals can be connected / disconnected whilst COBALT8 is powered on, however “Negative / Normally Closed” pedals must be connected before powering on the device and disconnected after powering off the device, else the sustain pedal behavior will be reversed. If your sustain pedal has a polarity switch we recommend setting it to the “Positive” polarity.
If you are unsure of your pedal’s polarity type, it is recommended to only connect / disconnected the pedal whilst the device is powered off.
