Ondomo - Legacy Of Love
With over 16 years of research into what makes the ondes Martenot a singular electronic
instrument, this revolutionary compact design from Japan brings accessibility, ease of
transport and playability to Maurice Martenot’s original vision.
With Ondomo you can bring the music with you anytime and anywhere, packing an
impressive list of features into a fully contained instrument that’s just 64 cm (25”) wide.
Equipped with a powerful built-in speaker, all you need is a power outlet to instantly
connect to the haunting, unmistakeable characteristics of sound that the Ondes
Martenot is famous for.
It is with the goal of sharing this expressive, dynamic electronic instrument that
inspired the creator to devote himself to this legacy of love.
• 4 octave keyboard with lateral movement for natural, expressive vibrato
• Ring controller for continuous control over pitch across full keyboard range
• Highly expressive ‘Touche d’intensité’ for minute control over volume
• Martenot-inspired‘Tiroir’ (control box) with timbre, mixing and pitch controls
• Analog oscillators hand-soldered and assembled in Tokyo, Japan
• Outputs: 1 powered 1/4” (speaker / diffuser) and 1 stereo line-level 1/4”
• Accessories: Legs / Power Adapter / Volume pedal (optional)
TECHNIQUES AND EXPRESSION
Like a stringed instrument wherein the position of the left hand
determines the pitch and the right hand the expression and volume
of the instrument, the Martenot splits its controls for sound creation
between your two hands.The pitch is controlled with the right hand,
using either a ring attached to your index finger or the keyboard,
and the left hand controls the dynamics and articulation with the
‘Touche d’intensité’ and the timbral controls of the ‘Tiroir’.
DESIGN AND CONSIDERATIONS
Each part of the Ondomo was painstakingly designed to accurately
reproduce the highly sensitive elements of the ondes Martenot.
From the ‘Touche d’intensité’, often referred to as the ‘soul of the
instrument’, to the keyboard with its unique lateral vibrato.
The ‘Tiroir’ is a hybrid of several generations of Martenot’s designs,
and offers a wide variety of timbral and momentary pitch controls,
in addition to the impressive three output mixer.
SPEAKER
The Ondomo features a powerful built-in speaker, allowing you to
perform without the need to bring additional heavy equipment.
We have also ensured compatibility with the original range of Martenot’s
diffuser / speakers (Palm, Metallic Resonator, etc.). Recreations
are on the horizon.

RING TUNING PROCEDURE
1. Press and hold both the Pand Kbuttons ( A ) while Ondomo is powered off.
2. While holding the buttons down, turn on Ondomo’s power switch ( B).
When the TOUCHE ( C) lights up, and no other lights are lit, release the Pand Kbuttons.
3. Move the Ring to the highest C of the keyboard.
4. Press the Kbutton ( A). The LED will illuminate.
5. Move the Ring all the way to the lowest C of the keyboard.
6. Press the Pbutton ( A). The LED will illuminate.
7. Press the center GAMELAN button ( D).
8. Tuning is now complete.

TIMBRE FINE-TUNING
Nknob:
Changes the width of the pulse wave.
Turning this knob clockwise will result in a
more distinctive, nasal tone, but the sound
will be more susceptible to cutting-out in
the higher frequencies.
Cknob:
Changes the amount of peak-limiting of
the waveform. Turning it fully clockwise
will result in a similar timbre to GAMBE.
Turning it fully counter-clockwise will
result in a similar timbre to ONDE.
BALANCE ADJUSTMENT
The volume of the N, C, O, Gtimbres can
be individually adjusted by using a small
flat-head screwdriver. By default, Ois
maximized, and N, C, and Gare set to an
equivalent volume.
MIXER
1slider:
Adjusts the volume of the internal speaker.
2slider:
Adjusts the volume from the powered
output ( 1). (Figure below,Tiroir left side).
3slider:
Adjusts the volume from the right channel
of the stereo line output ( 2).
4slider:
Adjusts the volume from the left channel
of the stereo line output ( 2).
OSCILLATOR WAVEFORMS
Each button activates a different sound waveform / timbre. Using different timbres
simultaneously allows you to produce a wide variety of sounds with Ondomo.
N: NASILLARD - Pulse wave
Similar in timbre to a bassoon in low registers.
O: ONDE - Sine wave
Similar in timbre to a flute or ocarina.
T:TUTTI
All waveforms simultaneously.
8: OCTAVIANT - Sine wave with 1st overtone on the octave
The degree to which the harmonic is present is adjusted with the slider ( 3).
C: CREUX - Peak-limited triangle wave
Similar in timbre to a clarinet in high registers.
G: GAMBE - Square wave
Similar in timbre to stringed instruments.
G: PETIT GAMBE - Square wave
Similar but less harmonically-rich timbre than GAMBE.
By adjusting the slider ( 4) your output can sweep through the full range of
waveforms present between the ONDE and GAMBE.
TOUCHE / INTENSITY KEY
Controls the volume of the sound during
performance. It remains silent until pushed;
the volume is adjusted with very careful
application of pressure.
SWITCHES
Pswitch:
Changes priority from high note (LED lit)
to low note when two or more keys are
played at the same time.
Kswitch:
Activates the “click envelope” mode when
using the keyboard.
GAMELAN BUTTONS
Increase the pitch by adding 2, 4 and 7
semitones (from left to right). Each button
works independently, and it is possible to
increase the pitch by various semitones up
to an octave by using them in combination.
GAMELAN work in both Keyboard and
Ring Modes.
OCTAVE SELECTION
Four ranges of octaves can be selected:
C1-C5, C2-C6, C3-C7 and C4-C8. The middle
button switches between the two middle
octave ranges.
FINE-TUNING KNOB
Adjusts the tuning of the keyboard.
KEYBOARD / RING MODE
C/B (clavier / bague) switch:
Switches between the Keyboard and Ring
performance Modes. On start-up, the
Keyboard Mode is active by default.

TIROIR LEFT SIDE
It is possible to connect a total of 3 outputs,
and by adjusting the use and intensity of
each diffuser (speaker) from the Tiroir,
you can achieve various ambiances.
A: Powered ¼” output*.
Adjusts the volume of the internal speaker.
B: Stereo line-level ¼” output.
A stereo to dual mono y-cable allows
you to connect two separate outputs.
C: Power input 12V.
D: Power switch.
TIROIR RIGHT SIDE
E: A standard expression pedal can be
connected to the ¼”jack on the right side
of the Tiroir. The foot pedal takes on the
role of the TOUCHE allowing for two-handed
passages to be played on the keyboard.
CONNECTIONS
* As Ondomo was designed to connect to
its own specially-made diffusers,connecting
directly to musical instrument amplifiers etc.,
may damage to the connected equipment.
