Illuminate your sound with the world's first keyboard controller to offer pitch bend and polyphonic aftertouch per key, as well as full-key illumination. This uniqueness sparks new ideas for playing and composing. For the first time ever on a keyboard controller, you can bend pitch with vibrato-like movements on each key and add depth to your sound with polyphonic aftertouch. Transform your tracks with acoustically natural expression through the four dimensions of touch - strike, press, slide and lift, making LUMI Keys the first "4D" keyboard controller. Hundreds of MPE and standard MIDI sounds, intricately crafted by ROLI sound designers, can be explored in ROLI Studio, the desktop software suite included with LUMI. Discover production features like Smart Chords that are advanced, intuitive and infinitely responsive as you fine-tune your sounds.
