I bought this keyboard to connect to an Android phone and this cable works very well except for the DRC synthesizer. To pair on an Android phone via Bluetooth you need to have the Bluetooth midi connect app and Bluetooth plus location enabled on the phone. You pair there and then select in the app. Connecting to a PC requires the microkey to occupy a midi port from 0 to 9 after connecting or it won't work. Korg has its own app to uninstall midi devices and you can use it to free up ports. Once everything is connected it works great. The keys are very light which is an advantage for me but may be a disadvantage for someone else. If it weren't for these minor connection issues I would give it 5 stars.
