Yamaha QY700 sequencer, used. It was used until recently, so it's working properly. I tested each key's sound and playback before listing it. Reading and writing floppies also works without any problems. If you have any questions, please ask in the comments section, and I'll answer them as best I can. It shows signs of use, with paint peeling and repaired cracks. The keys are not very yellowed. I carefully disassembled and cleaned it before listing. The display is working normally, although it's difficult to see in the photos. Also included are a Yamaha genuine adapter, data previously distributed by Yamaha, and floppies containing DEMO2/STYLE1/STYLE2. I will pack it carefully. Please understand that this is a used item in its current condition before purchasing. #yamaha #ヤマハ #qy #qy700 #sequencer #楽器 (musical instrument) #機材 (equipment) #DTM (Desktop Music) #ヴィンテージ (vintage) #打ち込み (programming/sequencing) #MIDI #シンセ (synth)
