Works perfectly fine and is fully functional. Please note that this is a 25–30-year-old controller, so it does show some normal signs of age and wear. The keys may also not feel quite like new, as the original lubrication has likely dried out over time.
Includes the original power adapter, dust cover, and a stand.
The SL-990 Pro does not have native USB connectivity. To use it with a modern computer, you’ll need a MIDI-to-USB adapter or an audio interface with MIDI input.
