● Yamaha MIDI Data Filer MDF3. Includes manual and AC adapter. ★ Reads both 3.5-inch 2DD and 2HD disks. While you occasionally see MDF2, which only reads 2DD, MDF3 is rare. I'm offering this from my secret collection. ● This unit itself doesn't produce sound; you'll need a sound module and speakers to play MIDI data. I've confirmed its operation by connecting it to a Roland SC-88 and SC-88VL sound modules via MIDI cable and outputting sound through Roland speakers. ※ This sequencer is compact and can run on AC power or batteries, making it very convenient. The ability to read 2HD disks is a particular selling point. I've used this to test most of my other sound module listings. ※ PC-9801 series ※ PC-9821 series ※ What's included: MDF3 unit, instruction manual, and genuine AC adapter. Other items shown are not for sale or are sold separately. 【Proposing the Seller's Reliability Index: Follower Ratio】 I propose using the follower ratio as a seller's reliability index. The logic is that people won't follow someone they don't trust. Therefore, it's a simple and clear way to measure reliability, based on objective data. Follower Ratio = Number of Followers ÷ Number of Listings Please use this to evaluate each seller. You'll be surprised at how clearly it reveals the seller's characteristics. ※ Whether you believe it or not is up to you, but try it and see. I think you'll be convinced.
