Like its predecessor, the
OASYS, the Kronos has multiple sound engines: 1) The
SGX-1 Premium Piano sound engine uses continuous (not looped) stereo piano samples sampled at eight velocity layers per key to produce a
Steinway-styled "German Grand" or
Yamaha-styled "Japanese Grand" acoustic grand piano; an optional
Bösendorfer-styled "Austrian Grand" sound set is available. The samples are directly streamed from the internal
solid state drive by using VMT (Virtual Memory Technology). This synth engine didn't exist on
Korg Oasys. With the release of Kronos 2,
SGX-2 Premium Piano superseded the SGX-1 sound engine. SGX-2 adds modeled string resonance and support for soft pedal samples and 12 velocity layers per key, making possible a new
Bechstein-styled "Berlin Grand" soundset which is factory installed on the Kronos 2. Older Kronos models receive an OS update which includes the SGX-2 engine. 2) The
EP-1 MDS Electric Piano sound engine offers four models based on specific classic
Rhodes electric pianos and two based on
Wurlitzer pianos, with software control over hammers, tines, reeds, and mechanical noise elements. It also simulates amplifiers, cabinets, speakers, and effects associated with those historic electric pianos. This synth engine didn't exist on Korg Oasys. 3) The
CX-3 Tonewheel Organ engine is carried over from the
Korg CX-3 modeled
tonewheel organ released in 2001 (not Korg's 1980 CX-3 based on octave-divider technology). The CX-3 engine models a classic tonewheel organ, including rotary speaker effects, vibrato and chorus effects, and tube amplifier. Nine hardware sliders on the Kronos' control panel function as organ drawbar controllers. This synth engine first appeared on Korg Oasys. A significant upgrade to this engine was made in November 2013 with OS 2.1 which improved both the organ model and the Leslie speaker simulation, and was accompanied by two extra banks of organ patches. 4) The
HD1 High Definition Synthesizer, which Korg first introduced in the
OASYS, uses
sample-based synthesis and
wave sequencing to generate sounds from the multisamples stored on an internal
solid state drive. The capacity of the built-in preset PCM ROM is 314 MB. 5) The
MS-20EX Legacy Analog Collection models an expanded version of the original
Korg MS-20 semi-modular monophonic analog synthesizer originally released in 1978. This engine is basically an update to the version released by Korg in their "Legacy Collection" software. It is also found on Korg Oasys as part of the LAC-1 engine. 6) The
PolysixEX Legacy Analog Collection models an expanded version of the 6-voice
Korg Polysix analog synthesizer produced by Korg from 1982-3. Similar to the MS-20EX, this engine is also an update to the version in Korg's "Legacy Collection" software, and can be found on Korg Oasys as part of the LAC-1 engine. 7) The
AL-1 Analog Synthesizer models analog
subtractive synthesis, with a range of modeled oscillator waveforms, filters, hard sync, analog-style FM, and ring modulation. This is another sound engine passed down from the Korg Oasys. 8) The
MOD-7 Waveshaping VPM Synthesizer is capable of classic FM sounds and has import compatibility with
Yamaha DX7 SysEx formatted sounds. The MOD-7 engine also combines Variable Phase Modulation (VPM), waveshaping, ring modulation, samples, subtractive synthesis, and modular patching to create a wider range of sounds than would have been possible on a classic Yamaha DX-series synthesizer. This synth engine first appeared on Korg Oasys. 9) The
STR-1 Plucked Strings engine creates sounds derived from the physical properties of struck or plucked string sounds. This sound engine is well-suited for creating sounds like guitar, harpsichord and clavinet, harp, and bell sounds, as well as other sounds based on the physics of a plucked string but not directly related to any known instrument. The STR-1 was first released as an expansion to the Korg Oasys. ==Other capabilities==
