From acoustic instruments to gritty analog synths, the Korg Kronos's nine synthesis engines can provide every sound you need. Simply put, if you took any of these individual synth engines and loaded them into an independent keyboard, you'd have a perfectly legitimate instrument most professional performers would be happy to play. All put together, this multi-faceted synthesis environment lets you access thousands of sound and layer them into rich and engaging music beds. This lets you play deep and complex sound and full instrumental arrangements, all without the need to switch presets or pre-record backing tracks.
