Check the listing for details. Arranger Module Korg I3 2020 Synthesizer Module With H4MIDI Mapper. Condition: Used, Made in Japan. Listed at 500.00 USD. PLEASE READ AND SEE VIDEO this was a keyboard that unfortunately got damaged and unable to repair the case ,so i instead I turned in to a working arranger module see the video, but in order to have it to work I had to buy a H4MIDI mapper in order to change the midi setting and to have working with midi usb connection, I include with the sale the module, the midi mapper and all cables needed for the connection, ******NOTE***** the only thing is that auto start stop is not working perhaps that can be configured with the midi mapper and for some reasons the left and soind voices are inverted basically lower sounds will play on the right side of the 88 keys piano and the upper voices will play on the left side of the piano ..
