  • Page 3 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.

  • Page 16 Normalisation Path A feedback path is created between the inputs and outputs on Lúbadh. Output of deck 1 is normalled to the Input of deck 2, which then passes to the Output of deck 2. The Output of deck 2 is normalled back to the Input of deck 1.
  • Page 17 Record, Overdub & Erase The Lúbadh currently records 9 minutes of audio per deck. It is important to note that the record head and the play head are decoupled. For instance, ½ speed playback can be set while full speed recording is taking place. To record to a deck, connect an audio signal to the Input of deck 1 and monitor from the Output of deck 1.
  • Page 18 Latching & Momentary Recording The Record Gate Input can be configured to Latching or Momentary. When set to Latching, the record state will change with every trigger or gate signal present at the Record Gate Input. When set to Momentary, the recording will be enabled for as long as a gate signal is held high.
  • Page 19 Input Monitoring Modes There are three Input Monitoring Modes. To toggle through the three Input Monitoring Modes, press and hold the Retrigger/Shift Buttons (1& 2) for deck 1 and deck 2, then press the corresponding deck’s Record Button (3). For example, deck 1’s Record Button is included in the button combination to toggle through Input Monitoring Modes for deck 1.
  • Page 20 Input Monitoring Enabled Mode This mode is indicated by a white illuminated Record Button (1). When this mode is active, input monitoring is always enabled. Audio signals present at the corresponding TIME TIME input will always pass to the output, summing with any recorded loops.
  • Page 21 Looping & One-shot Record Modes To toggle between Looping Record Mode and One-Shot Record Mode, Press and hold the Retrigger/Shift Button of the desired deck, then press the Record Button of the opposite deck. For example, to toggle between Looping Record Mode and One-Shot Record Mode on deck 1, press and hold the Retrigger/Shift Button (1) of deck 1, then press the Record Button (2) of deck 2.
  • Page 22 • Looping Record Mode is the default mode. • In One-Shot Record Mode, a loop must be recorded to determine the size of the loop. Any further recording will start from the current playback position and will record for the duration of time set by the first loop along with the Start and Length parameters.
  • Page 23 Looping & One-shot Playback Modes To toggle between Looping Playback Mode and One-Shot Playback Mode, Press and hold the Retrigger/Shift Button of the desired deck, then press the Erase Button of the opposite deck. For example, to toggle between Looping Playback Mode and One- Shot Playback Mode on deck 1, press and hold the Retrigger/Shift Button (1) of deck 1, then press the Erase Button (2) of deck 2.
  • Page 24 • Looping Playback Mode is the default mode. • In One-Shot Playback Mode, a loop must be recorded to determine the size of the loop. Pressing the Retrigger/Shift Button or sending a gate or trigger signal to the Retrigger Input will start playback of a full loop determined by the Start and Length parameters.
