The super matte black Korg KROSS 2 is a mobile synthesizer workstation with a 61-key, velocity-sensitive keyboard. Combining a synth, sequencer, sampler, recorder, and audio interface in one compact and lightweight unit, it provides musicians and composers alike with the tools for writing and recording original music, or for performing as a one-man band or in a group.

The KROSS 2  offers 1000+ preset sounds, 120 voices of polyphony, 134 effects, and 128MB of built-in expansion PCM memory for optional sound libraries as they become available (available separately). The workstation is equipped with a sampling function that provides 16 playable pads for triggering samples or full audio tracks.

For production applications, the KROSS 2 comes with a 16-track MIDI sequencer, a step sequencer, an arpeggiator, and a drum track. A stereo audio recorder enables you to record your performance or overdub an external input source—such as vocals—directly to an SD card (available separately).

The workstation features a user-friendly layout with real-time controls that let you easily access desired sounds and functions on the fly. You can quickly store and recall your favorite programs and combinations, and layers/splits are simple to set up thanks to a dedicated button.

In addition to USB MIDI interface functionality, the USB audio interface enables you to connect the KROSS 2 to your Mac or Windows computer and enjoy DAW recording.
