What Makes the Korg KROSS 2 61 Special?

The KROSS 2 manages to combine the functions of a synthesizer, workstation, sampler, sequencer and USB audio interface in a keyboard weighing only 3.8kg. That makes it an unusually practical option for musicians who need substantial creative capability without carrying a large workstation.

Its sound engine covers everything from acoustic and electric pianos to organs, strings, brass, guitars, drums, synth pads, leads and electronic textures, while sampling, sequencing and audio recording make it possible to turn those sounds into complete musical ideas.

Why Choose the Korg KROSS 2 61?

More Than 1,000 Ready-to-Play Sounds

The KROSS 2 includes a huge selection of sounds generated by Korg's EDS-i sound engine.

Its factory library covers acoustic and electric instruments alongside modern synthesis, drums and electronic sounds, while extensive editing lets more experienced users customise Programs to suit their own music.

Up to 120-Voice Polyphony

Maximum polyphony reaches 120 voices in single-oscillator mode, providing plenty of headroom for layered sounds, sustained passages and complex arrangements.

Actual available polyphony varies depending on the oscillator structure and multisamples being used.

16-Pad Sampler

A bank of 16 performance pads allows sounds from the keyboard or an external input to be sampled and triggered directly.

There are eight banks available, with up to approximately 14 seconds of stereo sampling per pad and playback of as many as four sampled pads simultaneously.

Full 16-Track MIDI Sequencer

The integrated 16-track MIDI sequencer can store up to 128 songs and approximately 210,000 MIDI events.

This makes the KROSS 2 much more than a preset synthesizer. Complete arrangements can be recorded and edited directly on the instrument, making it useful for songwriting and production without requiring a computer at every stage.

Step Sequencer and Drum Track

The 16 pads can also operate as a 64-step sequencer, providing an intuitive way to build rhythm patterns.

A dedicated Drum Track offers 772 preset patterns, allowing grooves to be added instantly while practising, composing or performing.

Powerful Arpeggiators

The KROSS 2 includes polyphonic arpeggiators capable of generating rhythmic patterns, chords, bass lines and guitar-style phrases.

Combination and Sequencer modes can use two arpeggiators simultaneously, opening up sophisticated layered and rhythmic performances.

USB Audio and MIDI Interface

Connecting the KROSS 2 to a computer by USB allows it to function as both a USB MIDI and USB audio interface.

For computer-based musicians, this makes it easier to integrate the keyboard into a DAW setup without necessarily requiring a separate MIDI interface.

Built for Musicians on the Move

At only 935mm wide, 269mm deep and 3.8kg, the 61-note KROSS 2 is exceptionally portable for a genuine workstation.

It can also operate from six AA batteries, making it useful for rehearsals, mobile production and performance situations where mains power may not be immediately available.

Why Choose a Synthesizer Workstation?

A synthesizer workstation combines sound generation with composition and production tools that would otherwise require several separate devices.

Rather than simply selecting sounds and playing them, a workstation lets you build layered Combinations, create rhythm patterns, record MIDI arrangements, manipulate effects and develop complete musical ideas.

The KROSS 2 takes this concept further with sampling and stereo audio recording while remaining much lighter than many traditional workstation keyboards.

Who Is the Korg KROSS 2 61 For?

Gigging Keyboard Players

Its low weight, broad sound library, quick Layer/Split functionality and extensive performance tools make the KROSS 2 ideal for musicians who regularly travel with their keyboard.

Songwriters

The MIDI sequencer, Drum Track, arpeggiators and audio recording provide plenty of ways to develop an initial idea into a more complete arrangement.

Producers

USB audio/MIDI connectivity, sequencing and sampling allow the KROSS 2 to work effectively alongside a computer-based production setup.

Synth Players

Deep Program editing, modulation, filters, effects and user arpeggio patterns provide considerably more creative scope than a conventional portable keyboard.

Students and Developing Musicians

Despite its depth, Korg has designed the KROSS 2 with straightforward category selection and quick access to important functions, making it approachable for musicians buying their first serious synthesizer or workstation.

Story & Context

Korg has a long history of professional workstation development, with instruments such as the M1, Triton, M3, Kronos and Nautilus establishing the company as one of the major names in integrated keyboard production systems.

The KROSS 2 was created around a different priority: portability. Rather than simply making another large workstation, Korg developed an instrument capable of delivering extensive sounds, sequencing, sampling and performance features in an ultra-lightweight chassis.

Compared with the original KROSS, the second generation expanded the sound library and PCM capabilities while introducing features including the 16-pad sampler and USB audio interface functionality.

Korg KROSS 2 61 Compared

KROSS 2 61 vs KROSS 2 88

The KROSS 2 61 uses a lightweight velocity-sensitive synth-style keyboard and weighs just 3.8kg, making it the stronger choice where portability and fast keyboard response are priorities.

The 88-note model uses Korg's Natural Weighted Hammer Action keyboard and is better suited to musicians who prioritise piano-style playing feel.

KROSS 2 vs Korg NAUTILUS

The NAUTILUS is a significantly more advanced professional workstation with multiple dedicated sound engines, touchscreen control, greater processing depth and more extensive performance capabilities.

The KROSS 2 is much lighter and more straightforward, making it particularly appealing to musicians who need workstation functionality in a highly portable instrument.

Frequently Asked Questions

Does the Korg KROSS 2 61 have weighted keys?

Fair Deal Music Verdict

★★★★★ 5/5

The Korg KROSS 2 61 is an impressive example of just how much workstation capability can be packed into an extremely portable keyboard.
