Sinevibes Intros Fraction Audio Slicing Workstation


Sinevibes has introduced Fraction Audio Slicing Workstation, a new OS X effect plugin, designed for ‘deep real-time manipulation and re-engineering of sound’.

Fraction features 8 slicers, which record and repeat small portions of the input audio at defined points in time, slightly or radically changing the rhythmical arrangement.

Each slice has three dedicated effect processors, with a wide range of algorithms, and their parameters can be animated in sync with the slice repeater. Rolls, stutters, fills, breaks and transitions can be done with ease.

Here’s the official video demo:


  • Real-time audio waveform preview for visual slice marker placement.
  • Eight audio slicers with individual size, repeat count, forward/reverse playback, duck and gate settings.
  • Variable slice trigger probability, realtime randomization for slice size and repeat count.
  • Eight slice sets each holding slice positions and on/off switches.
  • Thee separate effect units per slice with 15 algorithm types each: low-pass, high-pass, band-pass and band-reject filters, phaser, barber-pole phaser, positive and negative flangers, chorus, bit depth and sample rate reducers, analog drive, circuit-bent filter, frequency shifter and pitch shifter.
  • Four parameter animation generators per slice, hardwired to slice repeat rate.
  • Advanced transport sync algorithm with support for tempo and time signature automation.

Here are the official audio demos:

Fraction works with Logic, GarageBand, Live, MainStage, ReNoise, Reaper, Studio One, Digital Performer, Tracktion and other software that supports Audio Unit effect plugins. It comes in 32/64 bit format for Intel Macs running OS X 10.6 or later, and supports Retina screen resolution.

Fraction for OS X (AU) is available now for US $69, or as part of the full Sinevibes collection for $299.

  1. Still waiting on a Chaosillator based synth where everything is just attractors save for maybe a couple of envelopes and a filter

  2. “Oh! Go, bay-bee! I think my mojo’s rising! Cheeky!” But what if my paisley bell bottoms and Nehru jacket are in the wash?

  3. I just wish someone someone would use similar technology to make a simple, MIDI-mappable live looping plug-in. That way I could quickly sketch-out track layers in Maschine standalone. Akai added a looper to their MPC Renaissance/Studio software, and I don’t feel like waiting for Native Instruments to 1-up their hybrid groovebox competition — they’ll be busy trying to sell overpriced 8-knob MIDI keyboards (and, to their credit, evolving the face of live music expression with new [and overpriced?] beat juggling DJ and stem hardware) for who-knows how long.
