Ursa DSP Lagrange 

Ursa DSP Lagrange 


Lagrange is a unique stereo delay system producing other worldly echoes using granular techniques, where each grain is from a different point in the delay buffer:

  • Use basic settings to create immersive stereo imagery with clean early reflections to give instruments a clear place in the mix.
  • Use the feedback control to transform your sounds into droning evolving soundscapes.
  • Shorten the delay time to create unusual metallic chorus effects.

Lagrange is an effect unlike any other.

Steinberg Karlette

Steinberg Karlette

Karlette is a vintage tape delay with four independent delay heads and tempo sync.

These plugins are unsupported by Steinberg but they work fine (tested in Ableton Live 64 Bit)

Inear Display BOWECHO (excellent plugin!) 

Inear Display BOWECHO

BowEcho is a modular sound mangler based on 4 delay lines. It offers a large palette of sound design options thanks to 4 LFOs that can run at control or audio rate, 4 Mixers that can also act as gainers, basic filters, ringmodulators or stereo splitters, and the ability to route the output of each module the way you want.


  • 4 delay lines with optional tempo sync.
  • 4 “mixers” that can also act as gainers, basic filters, ringmodulators and stereo splitters.
  • 4 LFOs with optional tempo sync and the ability to run at audio rate.
  • flexible modular routing.
  • MIDI learn.
  • MIDI program change support.
  • Vector based resizable user interface.
  • Cross-platform presets.
  • 62 factory presets by Ivo Ivanov, Daed and Apparition.
  • Lifetime free updates for registered customers.

SoundHack Delay Bundle 

SoundHack Delay Bundle is a group of four plugins derived from the same basic delay algorithm: a hermite interpolated delay line with variable modulation, and a feedback loop with dc blocking and saturation. Pitch shifting is achieved with a dual head crossfading delay (ala Eltro Tempophon/Dennis Gabor/Pierre Schaeffer phonogene) and is decidedly retro. The saturating feedback also allows them to be great drone and noise generators.

soundhack ++delay

++delay gives you classic delay effects, with a wide ranging filter section to help emulate vintage delays, an LFO time modulator with triangle, sine, ramp, square and random waveforms, as well as freeze mode, dual-head mode and feedback inversion. Both the delay time and the LFO modulator can be synced to multiples and divisions of the host clock.

soundhack ++pitchdelay

++pitchdelay, is based on the same codebase as +delay, but the controls are oriented toward pitch shifting, giving you classic rotating head pitch shifting. Pitch can be adjusted in equal tempered semitones or just ratios with additional cents and octave controls. The time and depth controls can radically alter the quality of the pitch shifting, from subtle to comical.

soundhack ++bubbler

++bubbler is a granular delay in which grains are pulled from the delay line with randomized start time, delay time, reversal, panning and pitch shift values. As pitch shift can be distributed to multiple simultaneous grains, chords can be played with the on screen buttons, or by sending MIDI to the plugin. +bubbler uses 8 channels of grains which can give you an extremely dense cloud of sound. Good for creating ambient chordal washes from simple material.

soundhack ++flipper

++flipper is a simple sound reverser. It records sound into a delay line and after a little bit starts to play it back backwards. This plugin is somewhat hard to control, but works best when tempo locked to the host clock.
