The black Kronos 73 from Korg is a music workstation with a vast palette of sounds, integrated editing, detailed 8"(20.3 cm) TouchView display, 16-track sequencer, 16-track audio recorder, and extensive sampling capabilities. The keyboard features nine distinct sound engines, with each engine dedicated to authentically reproducing its respective instrument type, including detailed pianos, vintage keyboard sounds, tone-wheel organs, ethnic instruments, plucked instruments, analogue synthesisers, and more.

The sequencer can access any combination of sound engines and imported samples, and the 16-track audio recorder can be used for recording vocals, other instruments, and more. For arranging and inspiration, the instrument includes the company's KARMA technology for generating endless phrases, drum grooves, and full-blown backing tracks based on the notes and chords played. Drum Tracks generate drum patterns automatically; everything from a simple reference beat to a full-blown drum track.

The Open Sampling System can quickly sample an external audio source regardless of operating modes, and it can even resample the performance of the keyboard itself. The user sample bank allows custom samples to be loaded and played, taking advantage of the large SSD capacity. Additionally, the Kronos 73 functions as an advanced control surface, with a four-way joystick, ribbon controller, two assignable switches, and a Vector joystick. Nine sliders, eight knobs, and a number of switches provide real-time interaction with the keyboard sounds.
