While organizing my belongings, I found some nostalgic equipment covered in dust. For the listing, I connected it to a PC via USB and confirmed its operation on Windows 11. (Installed Vista drivers in compatibility mode → recognized and operated normally) I set the output in "MIDITrail" and confirmed that sound came out from the headphone jack on the front panel. When I played some old MIDI files, it was, well, emotional... ! 【Important Notes】 ・This listing is for the main unit only. Cables are not included. ・The AC adapter is missing. 　→ However, it can be powered via USB bus power. 　※When using bus power, please connect to a USB port that provides a stable power supply, such as the one on the back of the PC. ・Due to its age, there are some stains and scratches (please check the photos). Recommended for those who understand old MIDI sound sources, and for those who want to enjoy collecting or listening to nostalgic sounds. Thank you for your interest!
