KOMPLETE KONTROL MK2 MIDI controller with 61 keys. I purchased and used this about 5 years ago, but I'm selling it to organize my equipment. The D key on the left side of the keyboard is slightly raised, but it works without any problems. The touch sensitivity is also fine, but those who perform in real-time and are particular about the key press might feel a slight difference, so I'm offering it at a special price as a B-grade item. (I didn't find it inconvenient when using it for composing.) Please consider purchasing only if you understand the above. The sound source transfer code is not included. Only the main unit is included. - Model Name: KOMPLETE KONTROL - Number of Keys: 61 keys - Display: Dual LCD display - Functions: MIDI controller, transport control, preset function - LED: Blue LED backlight - Control Knobs: 8 encoders Thank you for looking.
