SAMURAI Classics – Japanese Koto instrument library

Vibrant Super High-Res Raw file

We at last present our most beautiful and vibrant Japanese Koto sound library. The pure raw files provided were captured using the same super high-res recording techniques utilised in Drum Tree and Shakuhachi Premier in 96kHz/24 bit.

Not merely High resolution sound, but an amazing beautiful tone has been created that washes over your heart, and great efforts have been made during recording to make sure not a single drop of this natural essence has been lost.


A Duo of Classical and Contemporary Koto Included

Japanese Koto: a 13 string instrument
17 string bass Koto, similar to a Cello.

The 13 string Koto covers B1-A4, simulating a typical Koto (Normal mode). Expand mode increases the range to A#4 – G5, with the use modern high pitched Koto. Kaguya covers the whole wide range of Koto instruments.

13 strings B1 – G5

17 strings C1 – E3


Complete playing style capability

All conventional Koto playing methods typically used in traditional Japanese music are covered. It is easy to switch between all 16 available styles with the simple and intuitive articulation panel and key switch.

For example, when using the “Real” style, note on begins the picking sound, and note off provides the sound of the string as you release the key. For “Normal” “Staccato”etc, note on creates a slight delay for the string sound after picking, to replicate a real koto. The delay time can be controlled using the pick knob, zero to 100ms.

The pitch bending (Up and down) aspect of Koto playing is achieved through the timing of releasing your keyboard, therefore you can control the timing of your bends to match the tempo of your song.

214 audio phrase patterns are also included, such as glissando etc. 

Real/Release Trigger (Picking sound as note is pressed, string sound as note is released.  Similar to real Koto style)
Normal (Picking and string as note is pressed)
Upward Picking
Pitch/Bend up
Pitch/Bend up semitone
Pitch/Bend down
Pitch/Bend down semitone
Bend 1 (The combination of up & down)
Bend 2 (Slightly pulling the string into a downward bend)
Alternate (Alternating down and upstroke playback)

36 traditional Japanese scales

As well as the standard chromatic scale, traditional Japanese scales can be assigned to the white keys of your keyboard. It is also possible to save up to 20 of your own original scales. You can perform glissando with white keys just like a real koto.


When using a preset, the top note of the 13 strings, A4, will automatically have tremolo assigned to the next black key, A#4. From this it is possible to reproduce SARARIN typical of traditional koto playing style, the combination of tremolo and glissando, without using any key switch. (F#4, G#4 also have the same automatic tremolo.)

The classic scales are usually played with the 13 string koto. However when using Expand Mode, the assigned scales intelligently and automatically extend to meet the higher/extra notes covered in Expand Mode.

All factory presets and user presets can be transposed to fit your song.


One of the reasons for the beautiful cosmic sound created by a Koto is that, similar to the way the pedals on a piano work, you are not only hearing the string that is being plucked, but also the vibrations and resonance that pass through all of the other strings and fill the surrounding air in all directions.

When recording the 13 string Koto, we captured all keys with authentic Koto scales. That’s why KAGUYA is imbued with super natural and beautiful vibration, typical of Kotos.

* The 17 String bass Koto is a contemporary instrument which was not used in the past. Therefore the 17 string koto only has the chromatic scale.


Other features

Stereo and center microphones are editable independently. Lo-cut is effective when you want to distance the stereo image arrangement. It can be hard bypassed when Lo-cut knob is zero.

Five varieties of convolution reverb are included. IR recorded in authentic, time honored Japanese Noh theatre.

And the image of Princess Kaguya’s moon also relates to the long, ethereal and mysterious reverb of the Koto, uniting both themes of Princess Koto – Kaguya.


From the moment you load this Koto sound library and let it ring out on your keyboard, the deeply stirring sound and emotion you will experience is something that the PREMIER Team has been striving to capture for the last 20 years. As the near mythical and magical Koto chords start ringing out, endless musical inspiration will take hold of you!
