Four Voices, Infinite Variations | Stretch Quartet + LFOs [Max for Live]

Stretch Quartet is an audio effect for Ableton Live

dedicated to time-stretching techniques.

It provides four independent buffers where you can record audio sequences ranging from 2 to 60 seconds, simply by clicking the Off / Rec button.

Each recorded sequence becomes an autonomous temporal layer with its own set of controls.

For every buffer you can adjust:

Pitch, from –48 to +48 semitones

Time-stretch playback speed, with negative values playing in reverse and positive values preserving forward time

Gain, allowing precise control over the balance between the four sequences

Stretch Quartet features five stereo outputs:

one master output containing the full mix,

and four dedicated outputs, one for each buffer.

This routing system allows you to build custom effect chains per sequence and to manage spatialization with great precision.

Stretch Quartet is a powerful tool for transforming a single sound into evolving textures

SHATTER break a sound into pieces and play them in space.

SHATTER is a browser instrument for live performance.
Load a sample and it splits into fragments you can scatter across a field:
click a piece to loop it, drag it to move it through space.
Every fragment is independent:
set its pitch, stretch it in time, reverse it, or give it its own step pattern.
Underneath, slices are cut at rising zero-crossings, so loops stay seamless with no clicks at the seams.
Time-stretching is granular and pitch-preserving so tempo and pitch move independently.
A fragment's position on the field drives a binaural HRTF panner (switchable to stereo):
left-to-right sets direction,
near-to-far sets distance,
placing each voice in space in front of the listener.
Step sequencers run free or lock to a shared BPM clock, with up to 16 voices at once.
Built as a single HTML file in vanilla JavaScript on the Web Audio API — no frameworks, no install.
It runs in any modern browser and reads WAV, AIFF and MP3.

Included in the download you'll find HTML Instruments,
a Max for Live device that lets you open SHATTER directly inside Ableton Live.
It requires Ableton 12 and Max 9.
Alternatively, you can run it standalone (just double click on html file) and route your computer or tablet output to your audio interface, just like any ordinary instrument.
