A 61-key MIDI keyboard with sliders and pads, and USB connectivity. - Model: Launchkey 61 MK4 - Number of Keys: 61 - Features: Sliders, knobs, and pads - Connection: USB - Color: Black Thank you for viewing. After purchase, I connected it and registered the product with Novation, but I have definitely deleted the registration before listing it, so please rest assured.
