Luppario

What it is

Realtime audio program to manipulate audio fragments in realtime, basically a combination of sound generation, volatile recorder/looper, processor.

Developed by Triceratupuz Lab

Key features

• Up to 47 second of looping time at 44100 Hz
• Waveform display
• Loop quantize
• modification of the loop by adding/subtracting/multiplying new sound
• output with binaural beats

Controls

Waveform visualizer

It shows the waveform of the audio signal currently stored in the memory. Its possible to set loop begin and end points by left and right mouse click respectively in the waveform area, see pointer sections to see how top toggle between the two sets:

• Actual - used in audio reproduction
• Desired - waiting for confirmation, preapare new loop points without interfere with audio reproduction

• red - scrubber, current point of reproduction
• dark green - actual loop begin point
• dark blue - actual loop end point
• light green - desired loop begin point
• dark blue - desired loop end point

Control widgets

The control widgets on the bottom of the interface are organized in three parts, midi mapping is reported at the end of the description for each control.

Loop and pointers

• Calculator
  

  The Calculator section allows to select the duration to be used by the subsequent sections (BPM calculator or loop quantization)

  • Dropdown menu -
  • horiziontal slider - set the minimum note number for the rotary knob
  • "Free"/"L.E." button -
• Loop
  

  The Loop section allows to

  • Set BPM -
  • Quantize -
• Pointers
  

  The Pointers section allows to

  • "Free"/"L.E." button -
  • ">>" button -
  • "<<" button -
  • "Act"/"Des" button -
  • "App..." button -

Audio generation/table manipulation

• Noise
  • Rotary knob - set the midi note for the lowpass filter of the white noise generator
  • Upper text box - set the minimum note number for the rotary knob
  • Lower text box - set the maximum note number for the rotary knob
  • Vertical slider - set the volume of white noise generator
  • "Q" button - quantize the pitch
  • "M" button - Mute the generator
  • "E" button - exclude the generated sound from the table input and send it directly to the effects (resonant LP filter -> reverb -> binaural ->out)
• Even
  • Rotary knob - set the midi note for the lowpass filter of the Even only harmonics generator
  • Upper text box - set the minimum note number for the rotary knob
  • Lower text box - set the maximum note number for the rotary knob
  • Vertical slider - set the volume of white noise generator
  • "Q" button - quantize the pitch
  • "M" button - Mute the generator
  • "E" button - exclude the generated sound from the table input and send it directly to the effects (resonant LP filter -> reverb -> binaural ->out)
• Odd
  • Rotary knob - set the midi note for the lowpass filter of the Even only harmonics generator
  • Upper text box - set the minimum note number for the rotary knob
  • Lower text box - set the maximum note number for the rotary knob
  • Vertical slider - set the volume of white noise generator
  • "Q" button - quantize the pitch
  • "M" button - Mute the generator
  • "E" button - exclude the generated sound from the table input and send it directly to the effects (resonant LP filter -> reverb -> binaural ->out)
• Operation and audio input
  • Rotary knob - Select the operation to be applied between generated/incoming audio and table stored audio
    on the bottom of the knob the operation is indicated
  • "Free"/"L.E." button - apply the new operation immediately or at the beginning of the next loop
  • Vertical slider - set the volume of line/external audio input
  • "M" button - Mute line/external audio input
  • "E" button - exclude the line/external audio input from the table input and send it directly to the effects (reverb -> binaural ->out, no LP filter)
• Preval
  • Rotary knob - set the amplification for generators/external audio to write in the table
  • Vertical slider - set the amplification for table stored audio to write in the table
  • "M" button - Mute the table output
  • "E" button - apply a declick envelope to the loop

Master effects

• LP
  • Rotary knob - set the frequency of the lowpass filter
  • Vertical slider - set the resonance of the lowpass filter
• Reverb
  • Rotary knob - set the Dry/Wet mix ratio
  • Vertical slider - set the room size
Mast
• Rotary knob - set the binaural separation frequency
• Vertical slider - set the overall output volume
