More sounds for KORG keyboards

KOMMEX is a MIDI expander with 770 sounds for KORG keyboards. There is a distinct difference between KOMMEX and other V3 SOUND models: KOMMEX was specifically developed as an integrated part of the keyboard itself. You can select 375 sounds directly on the keyboard while adjusting parameters such as volume, reverb, chorus or panorama. These sounds are just as easy to save and call as if they came straight from the keyboard. In addition, 395 additional sounds can be used in the edit area for styles and MIDI files. More below.

KOMMEX offers 4 GB flash memory, 15,000 samples, and 256-voice polyphony created with cutting-edge sampling technology. In order to display the KOMMEX voices on your keyboard, just upload the data from the following download link to your keyboard. Since the data files are only about 20 MB, the memory of your keyboard will not be limited by the addition of this V3 SOUND expander. The KOMMEX sounds, created by more than 20 sound designers, are saved in the flash memory of KOMMEX. You cannot fill this memory space with your own sounds.


Hardware Connection

To transfer the data, use a MIDI or USB connection between the sound expander and your keyboard. To hear the sounds, connect the KOMMEX audio out to the AUX-IN port on your keyboard, mixer, amplifier or powered speaker. See the user manual for specific instructions.


PIANO (17 Sounds)

Photo trumpetKOMMEX Grand Piano lets you dive into panoramas of piano sound. Samples of the renowned Vienna-made Imperial 290 concert piano create the heart of these sounds. The piano is also available in many musical varieties, such as rock, Latin or classical. Other sounds in this group include honky-tonk piano and harpsichord.

E-PIANO (46 Sounds)

E-pianos are represented by an electric grand (CP), an e-piano (Dyno), an A200 with 15 dynamic levels, a Clavinet D6, and a number of FM models (DX7). The sounds have multiple levels of note-off samples to create sounds as authentic as the real instruments.

TUNED (33 Sounds)

Metallophones, lamellophones and idiophones are all part of the tuned sounds. This group also includes the Glockenspiel, kalimba, music box, steel drums, vibraphone (with or without vibrato), xylophone, marimba, celesta and more. Many of these programs use Round Robin sampling technology, which produces an automatic shuffling of different samples when a key is pressed more than once. This brings your music to life – not only when playing single tones, but also when playing complete MIDI files and styles.

ORGAN (83 Sounds)

This sound bank includes a great selection of organs: jazz and German entertainer organs, each with fast and slow rotary effects, as well as English theater organs. Travel back in time with select sounds of the Cordovox electric accordion from the 1970s.

ACCORDION (72 Sounds)

Samples on instruments from Germany, Austria, Switzerland, as well as France, Ireland and Scotland make up this huge selection of accordion sounds. Sounds with great tremolo or “flat tuning” are available along with musette tuning and other specialties of French and Belgian instruments. Jazz lovers will enjoy the Super VI model and the Accordiona; friends of Swiss folk music will love the Schwyzer Örgelis; and Oberkrainer fans will like the two Alpine models. For Austrian music there are two Steirische Harmonikas.

All sounds have note-off samples: When you let go of the key, you can hear the resonance of the reeds and the housing. The sound does not stop abruptly; it resonates just like the real instrument. This resonance fills the space between the notes played. Without it, the accordion sounds become “on/off” music – artificial and not musical at all.

GUITAR (47 Sounds) | BASS (45 Sounds)

Variety is also programmed into the guitar sound bank. The wide selection incorporates everything from classical nylon guitars, jazz, electric and overdrive guitars to banjos and rhythm and pedal steel guitars. For Mediterranean flair, use the mandolin ensemble from Naples with tremolo and single picking. The integrated Round Robin function creates lively sounds.

To make the guitar sounds authentic using a keyboard, activate the slide-up samples by hitting a key hard. Give your music the right spice with samples that include string and fretboard noise, which are called up randomly by letting go of the key (note-off).

All about that bass: E-bass (also with a slap version), synth bass sounds and contrabass (plucked and bowed) are included in the sound bank, as well as a contrabass especially for traditional German folk music.

STRINGS (40 Sounds)

Highlights of the strings include a classical solo violin, a Celtic fiddle, and a Zillertaler violin, which are played with automatically alternating up and down bow. Since the range of a string instrument depends on its size, samples of violins, violas, cellos and contrabasses are distributed across the whole keyboard – with overlaps at the thresholds. Full strings can be played like an instrument. Disco and synth strings complete the selection of classical instruments.

BRASS (54 Sounds)

The brass sounds are represented by a variety of solo instruments: trumpet, coronet, horn, trombone and tuba, as well as a solo baritone horn for Oberkrainer music. The trumpet and trombone sections include articulations of falls, gliss-up, sforzato and shake. You can even add extras such as muted trumpets, tenor horn vibrato and a tuba ensemble.

SAXOPHONE (28 Sounds) | WOODWINDS (30 Sounds)

Members of the saxophone family – soprano, alto, tenor and baritone – have solo and sectional variations. Special articulations like smooth vibrato and funky growl enrich your play.

Oboe, English horn, bassoon, clarinet, piccolo, flute, panpipes, Celtic whistle (high/low), to name a few, are all included in the woodwind instrument group.

SYNTHESIZER (71 Sounds) | CHOIR (14 Sounds)

Our synth bank ranges from retro synthesizers and digital classics to standard dance sounds in many versions. Choirs are in their own sound bank in “aah”, “ooh” and “doo” varieties. Synthesizer voices are also available.


The ethnic instruments include a Scottish solo bagpipe, a group of “Highland Pipers,” an Irish Uilleann pipe with drones and an accompanying accordion for Celtic music, a 5-octave Appenzeller dulcimer and a 3-octave Tyrolean-style dulcimer. Solo alphorns and alphorn ensembles, cow bells, zither, harp and Jew’s harp can also be found in this sound bank. Many of these sounds use Round Robin technology to give your music richness and authenticity.

To round out the collection, there are 137 drum sounds also included in this bank.


Photo stringsThe orchestra instruments are intricately programmed and available in a wide variety – from a complete symphony orchestra (full strings) and chamber music ensembles to string ensembles with 14 violins, 10 violas, 8 cellos and 6 double basses. All the string instruments can be played in solo versions also, as well as in the most well-known effects, such as legato, marcato, détaché, pizzicato and bow tremolo.

For all string sounds, hitting the key hard also creates a hard bow sound on the virtual string. Round Robin technology is employed with strings also, resulting in the automatic switch between up and down bowing. This technology really stands out in détaché play. Note-off samples create natural tone fades, perfectly capturing the way resonance in string instruments can be heard for a long time after a note is played, softening the flow of the melody.

CLASSIC | BRASS (45 Sounds) & WOODWINDS (32 Sounds)

Photo brassThe V3 KOMMEX sound bank includes basically all orchestral wind instruments. You will find trumpets, trombones, tubas, horns, clarinets, and flutes in solo versions as well as ensembles and in a variety of articulations, such as marcato, sforzato and staccato. The Round Robin function plays a critical role here also, since 16th-note passages would not sound natural without it. Other instruments in this group include tenor horn, English horn, oboe, bassoon and contrabassoon.




Photo timpani

Over the years, the tasks of classical percussionists have become more complex and challenging. Today, up to 5 percussionists work together as a team in large orchestras. In V3 KOMMEX, you will find the necessary tools – from the small drum to the timpani, from the gong to the cymbals, from the xylophone to the marimbaphone, from the triangle to the tubular bells. Not even the celesta is missing, where steel plates are hit with felt hammers through a keyboard.




375 Sounds

KORG keyboards offer 4 x 128 memory slots for user sounds. We do not use USER Bank 1 because we need to keep these 128 spaces free for customized sounds. Therefore, it turns out that 375 sounds can be selected directly on the display.
