Works perfectly and comes with the rare upgraded sound library NR1 card, which gives you 297 single sounds and 100 performances. It is an SRam 64kB battery packed memory card built by Clavia and in mint condition. The module includes rack ears and still has the rubber feet on it as well. Unit has been debugged and deep cleaned for sale. All I/O has been sprayed with deoxit contact cleaner and prepped for shipment. This machine was manufactured in 2003 and in near mint condition. Some of the black rotary knobs have been replaced but this is purely aesthetic and does not affect the functionality whatsoever. Any questions please ask. Open to trades. Thanks for looking, have a wonderful day.
