Envelooper is a powerful envelope looper designed to create precise sidechaining effects and much more. It allows users to draw custom envelopes with editable points and curves, offering complete control over the volume modulation. The interface supports snapping to a customizable grid and provides options to randomize envelope shapes or load predefined patterns. Users can set the envelope duration using musical time divisions or milliseconds and choose between looping the envelope or playing it once. Additional features include mirroring envelopes, exporting and importing shapes, and adjusting the volume range to invert the effect.

Beyond volume modulation, Envelooper can control any parameter within Ableton Live through its mapping function. It also supports frequency-specific processing, enabling users to target a portion of the audio spectrum for subtle or dramatic effects. The tool includes smoothing controls to eliminate clicks and pops, phase shifting to move the envelope in time, and simultaneous tweaking of ascending or descending curve shapes. A follower mode triggers the envelope based on input signal thresholds, providing dynamic responsiveness without a sustain stage common in traditional envelope followers.

The latest version introduces a floating, resizable window for detailed envelope editing and real-time visualization of the envelope, input, processed, and sidechain signals. This visual feedback helps users fine-tune their effects with precision. Envelooper requires Max for Live, making it compatible with Ableton Live Suite or available as an add-on for other versions. The output gain control offers final adjustment for signal level, ensuring flexible integration within any mix. This tool is ideal for producers seeking advanced sidechaining and creative modulation beyond standard volume pumping.
