A mobile synthesizer keyboard with impressive features

With the KROSS, the sounds and songs that you've created at home and the system that you use every day can go with you onto the stage or into the street! Featuring rich sounds that exceed its class, yet remaining highly portable, the KROSS is designed for practical usability. There's a convenient mic input and a built-in audio recorder, and it can run on 6 x AA batteries. It's a distinctive new standard in music workstations, with specs and style that set it apart from all others.


KROSS 2, the long-awaited successor of the KROSS, is a compact, portable workstation with a huge range of sounds. While maintaining its identity as ultra-lightweight, compact, and capable of running on batteries, this new model dramatically enhances KROSS’s sounds and functionality. In addition to a total of more than a thousand preset sounds, expansion PCM memory has been newly added. Also new is a pad sampler that allows full-fledged sampling, and USB audio/MIDI interface functionality. The color scheme is even more stylish, and the user interface allows intuitive operation even by beginners. 

Effortlessly select the sound that you want to play, shape it to match your imagination, sample a sound, create phrases and rhythms, record your vocal or guitar, bring KROSS 2 on stage, and perform. Whatever you artistic vision, you can make it happen. KROSS 2 is a versatile synthesizer platform made with creative freedom in mind.
