Description
The harmonàig is a four voice voltage quantiser designed with
intuitive harmonic capabilities. It brings the possibility of composing
and performing chord progressions, and harmonising in a polyphonic
manner, to what is traditionally a monophonic instrument.
No deep understanding of music theory is needed!
Quickly sweep through modalities and chord voicings on-the-fly, and
explore a vast array of harmonic tones and colours. Explore practical
music theory in a familiar context and build your relationship with
tonalities that suit your own personal style.
The modal music system is used by the harmonàig to allow immediate
exploration of musical tonalities whilst keeping everything diatonically
relevant. Built in modal harmonisations give extensive foundations for a
wide spectrum of tonalities. With additional capabilities for user defined
chord voicings and note clusters, the creative options are endless.
In practice, users can experiment with chordal composition as quickly as
they would a monophonic bass or lead line. All that’s needed are a few
more oscillators!
Features
• CV input with built in attenuverter
• Individual CV outputs for up to four chord tones
• Slew controls for each CV output
• Transposition functionality
• Intuitive harmonisation and voice leading capabilities
• Modal and harmonic minor scale presets
• Four custom chord slots
• Large horizontal keyboard interface

Installation
1. Confirm that the Eurorack synthesizer system is powered off.
2. Locate 18 HP of space in your Eurorack synthesizer case.
3. Connect the 10 pin side of the IDC power cable to the 2x5 pin
header on the back of the module, confirming that the red stripe on
the power cable is connected to -12V.
4. Connect the 16 pin side of the IDC power cable to the 2x8 pin
header on your Eurorack power supply, confirming that the red
stripe on the power cable is connected to -12V.
5. Mount the Instruō harmonàig in your Eurorack synthesizer case.
6. Power your Eurorack synthesizer system on.
Note:
This module has reverse polarity protection.
Inverted installation of the power cable will not damage the module.
Specifications
• Width: 18 HP
• Depth: 27mm
• +12V: 120mA
• -12V: 20mA

Tuning
The harmonàig can be set Unison Mode to easily tune all of the
controlled oscillators. This disables the harmonisation functionality
so that R CV Output, 3 CV Output, 5 CV Output, and 7 CV Output
generate the same voltage.
To enter Unison Mode, press and
hold both the Diatonic Button and the
Transpose Button in that order, then
double tap the C Button. The amber
illumination of the C Button indicates
that Unison Mode is active.
To exit Unison Mode, press the
illuminated C Button.
Calibration Trimmers: The Calibration Trimmers are used to
independently scale the voltage range of each output. These are factory
calibrated with precision test equipment.
Calibrate at your own risk.

Global Modes
To switch between Quantiser Mode
and Performance Mode, press and
hold the Transpose Button and then
tap the Diatonic Button.
Inversion, Voicing, Chord Quality,
and Transpose controls are available
in both modes.
Quantiser Mode: The default behavior of the harmonàig is as a
harmonising quantiser. In Quantiser Mode, a single control voltage
signal present at the CV Input will be quantised and output from the
R CV Output. The control voltage is then duplicated and offset at
calibrated intervals and generated from the 3 CV Output, 5 CV Output,
and 7 CV Output. The offsets are dependent on the Chord Quality,
Inversion, Voicing, and Transpose parameters and vary on a per
output basis.
Performance Mode: The secondary behavior of the harmonàig is
as a harmonising performance keyboard. In Performance Mode,
the Keyboard Buttons become a playable interface. Each button
corresponds to a different root voltage. When a voltage is active,
the corresponding button will be illuminated. The CV Outputs are
dependent on the Chord Quality, Inversion, Voicing, and Transpose
parameters and vary on a per output basis. The gate output will be high
as long as a voltage is held.

Pitch Control
Keyboard Buttons: The Keyboard Buttons will enable and disable
chromatic voltages available in the desired quantised scale.
• We will refer to the Keyboard Buttons as the C, C#/D, D, D#/E,
E, F, F#/G, G, G#/A, A, A#/B, and B Buttons.
• Currently active voltages will be illuminated white.
• Enabled voltages are illuminated amber.
• Disabled voltages are unilluminated.
CV Input: The CV Input is a bipolar control voltage input for
the quantiser.
• Control voltage present at the CV Input will be quantised and
harmonised at the R CV Output, 3 CV Output, 5 CV Output, and
7 CV Output.
• Input Range: -/+10V (20 octaves).
CV Attenuverter: The CV Attenuverter scales and inverts the signal
present at the CV Input before it is quantised.

Transposition
Transpose Button: The Transpose Button will cycle through three
Transpose fader control settings.
• If the Transpose Button is unilluminated, the Transpose fader
is disabled.
• If the Transpose Button is illuminated amber, Quantised Offset
Mode is selected.
• If the Transpose Button is illuminated soft white, Global Quantised
Offset Mode is selected.
• If the Transpose Button is illuminated white, Global Fine Tune Mode
is selected.
Transpose: If the Transpose parameter is
disabled, the Transpose fader will not function.
Quantised Offset Mode: When engaged, the Transpose fader can shift
through a quantised -/+2V range (four octaves) of the
selected voltages.
• The value set by the Transpose fader sums with the signal present at
the CV Input.
Global Quantised Offset Mode: When selected, the Transpose fader
will globally offset the quantised voltages between a -/+2V range (four
octaves).
• The offset shifts in semitones and affects all four CV Outputs
simultaneously.
• This mode allows for a global re-tuning to an entirely new tonal
centre without the need of re-tuning each individual oscillator.
10
• Global Quantised Offset Mode will automatically time out to avoid
accidental detuning.
Global Fine Tune Mode is selected, the Transpose fader will globally
offset the quantised voltages between a -/+1V range (two octaves).
• The offset is unquantised and affects all four CV Outputs
simultaneously.
• This mode allows for a global fine tune adjustment of the voltages.
• Global Fine Tune Mode will automatically time out to avoid
accidental detuning.
Transpose Settings: The LED of the Transpose fader will illuminate when
the parameter is set above or below the 0V point found at the centre
dent of the Transpose fader.
• All Transpose settings will be retained between power cycles.
To reset the two global Transpose
offsets immediately, press and hold
the Transpose Button and double tap
the C Button.
