Korg Kronos 3 73 is a next-generation workstation that combines the power of nine independent sound engines with exceptional playability. This model features a 73-key RH3 (Real Weighted Hammer Action 3) keyboard, which faithfully reproduces the mechanics of an acoustic grand piano—heavier in the lower register and lighter in the upper. It strikes the perfect balance for pianists and keyboardists who demand full expressive control in a more portable format than the 88-key version.
The new Kronos 3 introduces a refreshed interface with an 8-inch color TouchView display supporting touch-drag gestures, along with an enhanced operating system featuring Seamless Sound Transition (SST) technology, ensuring smooth patch switching without cutting off effects. The instrument boasts an expanded SGX-2 piano engine with new Italian Grand and Berlin Grand samples, as well as a powerful 16-track audio/MIDI sequencer and an open sampling system. All of this is housed in a sleek metal chassis with new black wooden side panels, highlighting its premium status.
