Lubadh is a full-fledged looper module for modular synths, consisting of two independent channels.The combination of the two lets you record instantly (up to 2 minutes per channel), play back, overdub, trim, scan, pitch control, delay effects and much more.Well-thought-out controls make virtual tape manipulation precise and intuitive.In addition, the behavior and sound quality of the module can be greatly changed by switching the mode by button operation and the preset function introduced from firmware V2.

Since the output of each channel is internally wired to the input of the other channel, you can easily perform recording and playback of each other's channels, feedback-like patching, and create complex loops.

  • 2-channel looper
  • Sound recording is done at 96kHz / 24bit and internally processed at 32bit.
  • Record up to 10 minutes for each channel
  • Enhanced sample management: navigate files and folders, save and recall
  • Saturated analog input circuit
  • LED display for easy understanding of playback speed, position, and length
  • Tape speed control (Vari Speed) can be up to 4 times in both forward and reverse directions
  • 1V/Oct mode
  • A mode that can be synchronized to the input clock
  • Link switch that can switch between stereo and dual mono
  • Clock divider output
  • Start position and length can be quantized in time
  • AUX input / output for cross-fading between channels and voltage control
  • Both recording and playback are possible with loop or one shot
  • Recording mode that reflects tape playback direction and speed is also possible
  • multiple playheads
  • 2HP expander (included in the main unit) allows voltage control of all parameters
  • The reel part is a touch plate, which affects the speed of tape playback.

1. Overview

1.1 Interfaces

Many of Lubadh's knobs and slider controls control virtual tape transport and gain, and are intuitive to use.record the soundloopYou can do a surprising number of processes by creating a loop and using the controllers to change the playback state or overdub the sound.The functions of each operator are as follows. 

The explanation of each part is displayed by mouse over

1.2 Internal wiring between input and output

A feedback path is formed between each Lubadh input and each output.on deck 1outputis deck 2'sInputon deck 2outputsignal on deck 1Inputis internally connected to the , and patching breaks this connection.This feedback path is very useful, for example, when bouncing audio from deck to deck.




1.3 Recording, overdubbing and erasing

Lubadh can record 10 minutes of audio per deck.

To record to a deck, press Deck 1'sInputconnect the audio signal to theInput Levelto the center position of the knob, andOutput Levelset to the maximum value of full right.Record buttonPress to start recording.Position / Record Indicatorflashes to indicate Lubadh is recording.Record buttonPress again to stop recording.Playback of the recorded audio begins immediately,Position / Record Indicatorto indicate that it is playing.

1.5 Operation list by button combination

In addition to the basic operations and controls described above, Lubadh allows you to change various operation modes and perform file operations by button combination operations.
Below you'll find details about each mode and editing feature you can access in this way.

    2. Details of modes and functions

    2.1 Presets

    Lubadh allows you to use user-configured presets.You can switch between two presets in the edited preset for each Lubadh deck.The selection of two available presets is done in a file named 'PresetLoader.txt' in the Preset folder of the USB drive.This Preset folder also contains some factory presets so you can start playing right away. Inside the PresetLoader.txt file, you can insert any name inside the quotes of ' "PresetA:" ' and ' "PresetB:" '.

    Each preset is organized, edited and accessed via a USB drive.Edits to preset files are saved between power cycles.To restore a preset to factory settings, delete the desired file.A new copy will be created after the next power on.Note that these Preset files are simple text files (.txt), so you can edit, rename, play, and even share your favorite settings easily.

    To switch between deck 1 presets, press on both decks.Retrigger/Shift Button (1&2)on deck 1 while holdingErase button (3)PressTo switch presets on Deck 2, similarly(1&2)on deck 2 while holdingErase buttonPressNow you can switch between the two active presets.

    Factory preset
    • Tape Looper: One of the initial presets in V2 firmware. While following the functionality of V1 Lubadh, Vari-speed recording is incorporated,tape emulationcan be controlled at the top level.
    • Clean: One of the initial presets in V2 firmware. While following the functionality of V1 Lubadh, Vari-speed recording is incorporated,Crossfade Durationcan be controlled at the top level.This preset disables most tape emulation features.
    • Classic: This preset is set up to closely replicate the functionality of the V1, except that vari-speed recording is disabled.
    • Clockable: This preset is optimized for synchronizing loops using an external clock signal.It's a great starting point for chopping up loops or creating beat-repeat-like patches.
    • Multi-Tape: This preset uses multi-tap to achieve a multi-tap delay.
    • Sequencing Mono: This preset allows for 1V/Oct pitch change and retrigger delays, and is set to ensure that the pitch change occurs on trigger of a new note.
    • Sequencing Poly: A multi-tap version of the 'Sequencing Mono' preset above, with playback speed set to 'Hold'.This allows multiple taps to be active simultaneously, each played at a different speed or pitch, allowing for sequenced polyphonic playback of loops.
    • Melontron: A preset edited to make Lubadh look like a 'Mellotron'.It achieves 1-note polyphony by altering the pitch of looped samples using multi-tap and a 4V/octave sequence signal.
    • Octave-Delay: A preset edited to make Lubadh look like a pitch-shifting octave delay.
    • Broken Tape: This preset is a full-blown tape emulation for extreme pitch-shimmering distortion.

    2.2 Multi-tap

    Lubadh supports polyphonic playback.This is the ability to provide multi-tap delay functionality, like a classic analog tape looper reading a single tape loop with multiple cascading playheads.This function is ' Multi-tape '' Sequencing Poly '' Melontron '' Octave-Delay ' and curated with factory presets.

    Retrigger/Shift ButtonPressing creates a new playhead tap, starting from the current position in the buffer. If four playhead taps are enabled, the oldest tap is deleted and replaced when a new tap is created.

    In modes that can use multi-tap,Erase buttonWhile holding downRetrigger/Shift ButtonRemove playhead taps by pressing .You can also use the CV Expander's Erase Trigger Input to remove playback taps with an external signal.

    2.3 Quantize loop start and length

    Lubadh can be configured to quantize loop start positions and lengths, and only select lengths that are integer fractions of the loop size.For tempo-based loops, changing the quantized Start and Length parameters gives musical results related to the number of loop divisions.

    Below are the steps to quantize Start and Length.

    Retrigger/Shift Button(1)while holdingTime(2)Operate the knobs to select the start time and length quantize values ​​for the corresponding deck.The quantize value isPosition / Record Indicatoris indicated in a manner similar to Clock Division.The number of lit sections indicates the number of loop divisions.

    • No illumination of a section represents no quantization.
    • Section 2 illumination sets the quantize of the Start and Length parameters to 1/2.
    • Section 4 illumination sets the quantize of the Start and Length parameters to 1/4.
    • Section 8 illumination sets the quantize of the Start and Length parameters to 1/8.
    • continue in the same way.
    • If you need adjustments without quantization when quantization is enabled,Retrigger/Shift ButtonHold to manipulate the Start and Length parameters.

    2.4 Function of Time Knob

    The clock trigger signal isTime indicatoris indicated by a solid white light.

    Dub Level

    Sets the volume at which incoming audio is layered over existing old material when overdubbing. Since the Dub Level is the delay feedback amount, you can create a delay effect.

    In this mode,Time indicatorlights amber.


    User-Definable Parameters

    Time Knobscontrols the amount of user-defined type parameters such as 'Crossfade Duration', 'Tape Emulation Amount' and 'Speed ​​Slew'.

    2.8 Saving and Loading

    A 'samples' folder with 12 subfolders will be automatically created on your USB drive.Each subfolder can store up to 12 loops.Loop and folder numbers are like clock division settings.Position/Record IndicatorsIt will be displayed in.The number of lit sections indicates the folder number.Loops and folders are automatically ordered alphabetically.


    Save: To save loops to the USB drive, select the corresponding deck'sRetrigger/Shift ButtonErase buttonwhile pressingRecord buttonPress.

    For example, to save the loop of deck 1,Retrigger/Shift ButtonErase buttonon deck 1 while pressingRecord buttonPressSimilarly, to save the deck 2 loop, select Deck 2'sRetrigger/Shift ButtonErase buttonon deck 2 while pressingErase buttonPress.


    Link ToggleBy saving the loop when the switch is enabled,stereo fileto save.All loops saved by these save operations will be saved in the 'saved' subfolder inside the 'samples' folder on the USB drive.This 'saved' folder will always appear in the folder menu as 'folder 0' (Position/Record Indicators unlit).Each saved file will appear in reverse order in Folder 0.In other words, the first file in the folder is always the most recent recording. If there are no samples in the 'saved' folder, 'folder 0' will not appear as an option.

    To load a loop saved from one of the USB drive's 12 subfolders, select the corresponding deck'sRetrigger/shift Buttonwhile pressingErase buttonPress to enter the 'Load Menu'.

      2.9 Tails and tags

      After recording the loop, Lubadh continues to record a 250ms "tail".By adding this 250ms tail, we can crossfade from the end of the loop to the beginning while maintaining the timing set in the original recording.When loading loops, tails can be processed in different ways by adding the following tags to the loop filename:

      {s} - Silent tail (default)

      • This tag preserves the timing of the loaded loop, but adds silence to the end of the loop, reducing the volume during crossfades.
      • This tag is recommended for rhythmic loops where you want to keep crossfades short or don't want to use crossfades.
      • It's the same process as if you didn't tag the file name.

      {n} - No added tail

      • This tag allows for the smoothest crossfades, but looser timing.
      • Affects loop timing, as it consumes 250ms of the end of the sample for the crossfade.
      • This tag is useful for long ambient or long ambiences of musical events, such as when timing is not critical and a smoother transition is desired, or when a loop is prepared by adding 250ms of audio in advance for a crossfade. Recommended for tone materials.

      {c} - Copy tail

      • The timing of loaded loops is preserved, but there is no reduction in volume during crossfades.Clicks may occur at transitions, depending on loop edit points and waveform zero crossings.
      • This tag automatically copies the first 250ms to the end for use in crossfades.
      • This tag is recommended for rhythmic loops, but transitions may be heard in longer musical events.

      2. 10 mode reset

      Performing a factory reset restores all modes to their default settings below.

      • Input monitoring enabled
      • loop recording
      • loop playback
      • clock division

      To perform a factory reset,Retrigger ButtonWhile holding downRecord Buttons on both decksPressof both decksSpeed ​​Indicatorflashes to indicate a successful factory reset.This operation does not erase the audio recorded in the buffer.
