WORKING CONDITION: Excellent. All tested parameters function normally. The keyboard feels great, and all of the buttons and encoders track as they should. This Xpander sounds incredible!

Please note: a professional 5-conductor MIDI cable is included and must be used in this environment. Although all MIDI DIN connectors have 5 pins, some cables only utilize three wires and leave 2 pins unconnected to reduce production costs.

PHYSICAL CONDITION: Excellent. All keys, buttons, LED's, and rotary switches have been preserved and are in top physical condition. The metalwork and wooden end cheeks are in very good condition.
