Comes with the correct power supply. It has a couple of minor issues: the D2 key is raised and the E2 key is glued together, yet they still work. Also, two knob covers on the center console are missing, but the knobs function properly.

Using this Roland E - 96 synthesizer is easy. First, connect it to the correct power supply that comes with it. When playing, don't worry about the raised D2 key and the glued E2 key, they'll still play the notes as usual. For the knobs on the center console, even without the covers, you can adjust them freely. As for maintenance, keep it in a dry and clean place. Avoid spilling liquids on it. If you notice any dust, use a soft cloth to gently wipe the surface. This way, your synthesizer will keep working well for a long time.
