The Novation Launchkey 25 is a MIDI controller with 25 keys and integrates seamlessly with Ableton Live. This means that the MIDI controller is immediately set correctly when you connect it to your computer. The 16 velocity-sensitive pads have backlight. You decide for yourself what you use the drum pads for and what color they change. This makes the drum pads widely applicable and you keep the overview during production. With the faders you manage the output volume of the mix channels from your recording software. That way you can easily find the balance. Because the keys are velocity sensitive, you put more feeling into your piano playing. This creates melodies that sound less static.
