The SY-1000's sound engine can be played only by a guitar or bass (equipped with a divided pickup) that is connected to the GK IN connector.
* When the SY-1000 is connected via USB to a computer, the performance from the GK IN connector is converted to MIDI and can be sent to the computer, but the sound engine of the SY-1000 cannot be played from DAW software etc. on the computer.
