The Korg Kronos 73-key version has similar specifications and features as the 61-key version only it has weighted hammer action keys.

And its 73-key format makes it slightly bigger than its sibling.

In addition to its weighted keys, it comes with Korg’s 4-way Vector joystick controller that allows for more real-time control.

These controllers utilize its nine sound engines, which lets you choose from a wide selection of presets, which you can then personalize to taste.

The “Set List” feature is one of the features that stood out since it allows direct access to a combination, program, or song in the sequencer to play next.

Other noteworthy features include having a TouchView display, and having the ability to record up to 16 MIDI tracks and 16 audio tracks.

This is an all-around versatile workstation ideal for any studio and performance setting. Note that it is no longer part of 2023 Korg keyboards line.
