SooperLooper – live looping sampler

SooperLooper is a live looping sampler capable of immediate loop recording, overdubbing, multiplying, reversing and more.

It allows for multiple simultaneous multi-channel loops limited only by your computer’s available memory. The feature-set and operation was inspired by the impressive Gibson Echoplex Digital Pro (EDP).

When used with a low-latency audio configuration SooperLooper is capable of truly realtime live performance looping.

The application is a standalone JACK client with an engine controllable via OSC and MIDI. It also includes a GUI which communicates with the engine via OSC (even over a network) for user-friendly control on a desktop.

Features include:

  • Multiple simultaneous multi-channel loops limited only by available RAM.
  • Record, manually triggered, or via input threshold.
  • Overdub for adding more audio on top of existing loop.
  • Multiply, allows increasing loop length by repeating the initial loop beneath (include MultiInrease option).
  • Feedback control allows gradual loop fading, active during overdub/multiply and optionally during playback.
  • Replace audio in loop with new material.
  • Insert new audio into existing loop.
  • Substitute audio in loop with new material, while hearing existing material.
  • Reverse loop playback (even during overdub) at any time, or quantized to loop or cycle boundaries.
  • Trigger loop playback from start at any time, also supports OneShot triggering which will play the loop once then mute.
  • Mute the loop output at anytime.
  • Undo/Redo allows nearly unlimited undo and redo to previous loop states.
  • Rate Shift allows arbitrary rate change of loop from 1/4 to 4x normal.
  • Works anytime, even during loop record.
  • Save/Load loops in WAV format.
  • Scratch feature allows DJ-like position scratching (work-in-progress).
  • Tempo syncable to MIDI clock, JACK transport, manual or tap tempo, or existing loops.
  • Sync Quantize operations to divisions defined by the tempo, and/or existing loops.
  • Sync Playback can retrigger automatically to maintain external sync during playback.
  • SUS (Momentary) operation available for all commands for easy realtime granular.
  • Crossfading applied to prevent clicks on loop or edit operation boundaries (crossfade length is adjustable).
  • Peak metering for all inputs and outputs.
  • MIDI Bindings are arbitarily definable and can be configured to emulate existing setup (EDP, etc).
  • Key Bindings are arbitarily definable for the GUI.
  • OSC Interface provides the ultimate network-transparent control of the engine.
