Synth has been used in my smoke free studio only. Almost in mint condition.

Please note that there are a couple of pieces of plastic in the back that are super glued. I used those for cable management. It may not be possible to removed them but it does not affect the synth.

The Sequential Prophet X is a 61-key hybrid samples-plus-synthesis keyboard originally priced around $3,499. It combines a massive 150 GB internal library of high-fidelity stereo samples (developed by 8Dio) with two high-resolution digital oscillators and real stereo analog low-pass filters per voice.
