This is Pocket Miku. I bought it at a bookstore when it was first released. It looks like a toy at first glance, but it seems to be a special MIDI GM sound source with only channel 1 audio, equipped with a Yamaha chip. I wonder if it's an XG sound source since it's Yamaha? Therefore, it also had tones like piano that could be used on channel 2 and beyond. I think you can find a lot of information if you search. The appearance is quite clean, but since I used it connected to a PC at the time, I think there are some small scratches and dirt on the main unit and manual. The box was kept in a bookshelf with air conditioning and out of direct sunlight, so there is no sun damage. As a bonus this time, I will include the short USB cable that I used to connect to the PC. Micro B type. I will put it in the empty space of the package packaging material. I checked the power supply with batteries and a USB connection. Sound also came out using a pen. Batteries are not required when using a USB connection. It is unknown whether the software can be used on Windows 11, but it was recognized as a USB device (photo). I plan to wrap it in bubble wrap, put it in a cardboard box, and ship it via Rakuraku Mercari delivery. This is a used item that has been used, so it is not a beautiful item. Please understand that no claims or returns are accepted. #Hatsune Miku #DTM #MIDI #YAMAHA #Gakken
