Needless to say, it's a legendary machine. It works. The battery connector was rusty, so I've made a simple repair. Some switches don't work perfectly, but it can be used without any problems. DIN sync and other functions have been confirmed. A DIN-TRS mini-plug cable is included. An Arturia Keystep is included. Using this allows synchronization with a DAW or MIDI. The keys may not function well if not used for a long time, so they're not in the best condition, but please use it as a converter. Consider it as a bonus!
