 ON (MIDI OUT): Performance data received from the SPD-SX PRO’s MIDI IN connector will be sent to the MIDI OUT connector.
 ON (USB MIDI): Performance data received from the device connected to the SPD-SX PRO’s MIDI IN connector will be sent to the USB COMPUTER port.
 ON (MIDI+USB): Performance data received from the device connected to the SPD-SX PRO’s MIDI IN connector will be sent to the MIDI OUT connector and the USB COMPUTER port.- Soft Thru USB MIDI In - OFF, ON - Performance data from a computer connected to the SPD-SX PRO’s USB COMPUTER port can be transmitted to a MIDI device connected to the MIDI OUT connector. - OFF: Performance data received via the SPD-SX PRO’s USB COMPUTER port is not transmitted to the MIDI OUT connector. 
 ON: Performance data received via the SPD-SX PRO’s USB COMPUTER port is transmitted to the MIDI OUT connector.- Local Control - OFF, ON - Connects (“ON”) or disconnects (“OFF”) the performance data from the pads to/from the sound module of the SPD-SX PRO. 
 This should normally be set to “ON”. If this is “OFF”, the performance data from the pads is not connected to the SPD-SX PRO’s sound generator section.- Device ID - 17–32 - Sets the device ID. 
 The setting described here is necessary only when you wish to transmit separate data to two or more SPD-SX PRO units at the same time.
