System Exclusive messages. This is also sometimes refered to as a “bulk dump”. This allows

• Transfer the memory contents from one Ground Control Pro to another.
To transmit the memory, first enter Setup mode by pressing both [SETUP MODE] buttons at
the same time. Then select this category by pressing [MIDI]. Press [SELECT
