Check the listing for details. Nektar Impact LX Mini 25-key Keyboard Controller. Condition: New. Listed at 119.99 USD. Take Your Impact LX Mini on the Road! If you want the power of the Impact LX+ series without the extra keys and faders, the LX Mini is for you. Based on the award-winning Panorama and LX49+/LX61+ before it, the Nektar Impact LX Mini USB MIDI controller uses intelligent mapping to give you hands-on control of your DAW session. Take advantage of the instrument mode to take control over parameters in your DAW and virtual instruments. The Impact LX Mini's synth-action keys give you a smooth, precise feel. In fact, all controls on the LX Mini — including the knobs and performance pads — feel great. At Sweetwater, we especially enjoy the Part 2 feature that allows you to shift octaves, transpose, layer octaves, or switch to differing MIDI channels.
