I connected a MIDI keyboard and confirmed that sound output from MAIN OUT/PHONES, sound changes, and the operation of various buttons all worked without issue. There were no jumps in the values of the knobs. Only the above simple operations have been confirmed. Accessories are as shown in the photos. In my subjective opinion, the exterior condition is quite clean! No smoking, no pets. Please, no claims and no returns. ◇ We ask for no claims and no returns. ◇ Please be aware of any scratches that may not be visible in the photos.
