The Alesis V25 is a MIDI keyboard with 25 velocity-sensitive keys, 4 knobs and 8 drum pads. Because the keys are velocity sensitive, you put more feeling into your piano playing. As a result, the melodies you play sound less static and you create a human feeling in your productions. With the 4 knobs you control software functions on the computer. You can link parameters of effects and audio processors yourself. Tap in on rhythms with your fingertips. For this you use the 8 drum pads. Do you want to extend keystrokes with your foot as a real pianist? Then connect a sustain pedal with the keyboard.
