Description
Consisting of two identical channels Lúbadh allows you to instantly
record, playback, overdub, trim down, scan through and pitch up or
down any audio signal.
Inspired by the aesthetics and mechanics of early tape techniques
each channel features an analogue input circuit which adds slight
compression, filtering and saturation. On the first recording, the sound
may appear slightly fuller and warmer, re-recording audio back and
forth will compound this effect over time allowing you to create dense
tape-like textures.
Features
• 9 minutes of recording time per loop
• Dual recording, looping, and overdubbing capabilities
• One-shot play and one-shot record modes
• Delay and reverb diffusion networks
• Tape decay mode
• Feedback functionality
• Capacitive front panel for flange and stall effects
• Includes 2 HP passive CV expansion module & 4GB USB flash drive

Installation
1. Confirm that the Eurorack synthesizer system is powered off.
2. Locate 20 HP of space in your Eurorack synthesizer case for the
module.
3. Locate an additional 2 HP of space in your Eurorack synthesizer
case for the optional CV expansion module.
4. 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.
5. 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.
6. Optional: To install the CV Expander module, connect the included
12 pin IDC cable to both modules. Ensure that the red strip of the
IDC cable matches the white stripe on each module.
7. Mount the Instruō Lúbadh in your Eurorack synthesizer case.
8. Power your Eurorack synthesizer system on.
Note:
This module has reverse polarity protection.
Inverted installation of the power cable will not damage the module.

Deck Specific Parameters
These parameters are specific to each deck, but function identically
regardless of deck.
Input: AC coupled audio input.
Input Level: The Input Level knob sets the level of the signal present at
the Input.
• If the Input Level knob is at its centre position, the signal present
at the Input will be set to unity gain. Any setting beyond the centre
position will add gain to the signal present at the Input. High signal
levels will experience analogue limiting and saturation keeping the
codec from digitally clipping.
Input Indicator: The Input Indicator will illuminate amber when a signal
is present at the Input.
Output: AC coupled audio output.
• The Output of deck 1 is normalled to the Input of deck 2, and
the Output deck 2 is normalled to the Input of deck 1, creating a
feedback path. This allows for the transfer of loops from one deck to
the other, as well as feedback, delay, and diffusion effects (See the
Delay Mode section for more information).
Output Level: The Output Level knob sets the level of the signal present
at the Output.
Pre/Post Output Level Switch: Two Pre/Post Output Level Switches
are located on the back of the module. There is one for each deck.
These switches determine whether the Auxiliary Output Crossfade is set
to be pre output level or post output level.
Record Button: The Record Button allows for recording, overdubbing,
and playback based on the currently selected mode.

• The Record Button is also used to enter alternate modes (See the
Input Monitoring Modes,Looping & One-Shot Record Modes,
Save & Load, and Time Modes sections for more information).
Record Gate Input: Recording, overdubbing, or playback (based on the
currently selected mode) will be activated when a trigger or gate signal
is present at the Record Gate Input.
Erase Button: Any loop in the buffer will be erased when the Erase
Button is pressed.
• The Erase Button is also used to enter alternate modes (See the
Latching & Momentary Recording,Looping & One-Shot Playback
Modes and Save & Load sections for more information).
Position/Record Indicator: The position of the play head within the
loop is shown by the Position/Record Indicator.
Speed: The Speed knob sets the playback rate of the loop.
When the knob is fully clockwise,
the rate of playback will be set to
4x the original speed. When the
knob is fully anticlockwise, the rate
of playback will be set to 4x the
original speed, but playback will
be reversed. When the knob is
set to its centre position, playback
will be stalled. Because this is a vary-speed control, setting the rate of
playback to half the original speed will also lower the pitch by
one octave.
• Pressing the Retrigger/Shift Button and turning the Speed knob
will mute the knob turn to allow for immediate speed value selection
upon release of the Retrigger/Shift Button.

Speed CV Input: The Speed CV Input is a bipolar control voltage input
for Speed.
• Control voltage is summed with the knob position.
• Input range: -/+5V.
Speed Indicator: The Speed Indicator will illuminate white when the
Speed parameter is set to a value that corresponds to the 0.5x playback
rate, reversed 0.5x playback rate, original playback rate, reversed
original playback rate, 2x playback rate, reversed 2x playback rate, 4x
playback rate, reversed 4x playback rate or stalled playback.
Length: The Length knob controls how much of the loop is played before
resetting to the loop’s start position set by the Start knob.
• Lúbadh can record up to 9 minutes of audio per deck.
• When the knob is fully clockwise, the entire loop will play. When
the knob is fully anticlockwise, the loop will be as small as possible,
creating a wavetable-esque sound source (scrub through the
sample via the Start knob for different wavetable-esque effects).
Start: The Start knob sets the start position of the loop.
• Moving the knob from anticlockwise to clockwise increments the
start position from the beginning of the loop to the end of the loop.

Retrigger/Shift Button: The loop will reset to the start position set by the
Start parameter when the Retrigger/Shift Button is pressed.
• If deck 2 is out of phase with deck 1 and the Link Toggle is enabled,
pressing the Retrigger/Shift Button of deck 2 will spin the tape in
either direction to resynchronize with deck 1.
• The Retrigger/Shift Button is also used for entering alternate modes
(See the Latching & Momentary Recording, Input Monitoring
Modes, Looping & One-Shot Record Modes, Looping & One-Shot
Playback Modes, Save & Load,and Time Modes sections for
more information).
Retrigger Input: The loop will reset to the start position set by the Start
parameter when a trigger or gate signal is present at the
Retrigger Input.
Clock Output: The Clock Output generates a trigger signal based on
the size of the loop and the value set by the Time knob.
Time Indicator: The Time Indicator illuminates white when a trigger
signal is generated at the Clock Output. It will also illuminate amber
when Time Modes are enabled (See the Time Modes section for
more information).
Time: The Time knob sets the multiplication factor of trigger signals
generated at the Clock Output.
