Rediscovering Pulse Engine: A Generative MIDI Toolkit for Intricate Rhythms and Dialogic Composition

Noah Pred returns to Pulse Engine, his modular MIDI invention for Ableton Live, to build a full track from scratch using only generative layers. Bass, pads, leads, and chopped vocal textures evolve through randomized decay, LFOs, and call-and-response logic—yielding a hybrid composition rooted in minimalism, IDM, and interactive design.

Dive into generative call-and-response composition with layered polymetric motion and live MIDI manipulation

In his latest livestream session, Noah Pred brings the Pulse Engine back into focus—reminding us that we don’t always need new gear to unlock fresh creative energy. Developed as a generative MIDI effect for expressive, unpredictable rhythms and call-and-response interplay, Pulse Engine is now integrated with Manifest Audio’s Sonification Bundle, and continues to evolve with use cases for both installation-based work and studio composition.

Rebuilding from the Basics: Endless Pulse Variations

Pred starts from scratch, dropping in a fresh instance of Pulse Engine and linking it to a multi-sinewave bass patch. He showcases how pitch and rhythm are both modulated via randomized triggers, decay settings, and embedded LFOs—making it easy to sculpt dynamically evolving motifs in real time. From triplet-based rhythmic clusters to chromatic glissando gestures, every parameter can be automated or linked to macro controls for hands-on expressivity.

From Solo Voice to Sonic Dialogue: Call-and-Response MIDI Mapping

As the session progresses, Noah demonstrates Pulse Engine’s “fill mode” and “gate mode”—configurations designed to play notes only when other MIDI activity is silent or active, respectively. By setting up multiple Pulse Engines to “talk” to one another through MIDI routing, he creates a modular dialogue between bass and keys, resulting in generative counterpoint lines and harmonically responsive fills.

Sampling, Slicing, and Polyrhythmic Textures

In a more experimental turn, Pred records his voice, slices it inside Simpler, and then triggers the samples using Pulse Engine’s high-speed output. Layered with comb filters and randomized panning, the sliced voice becomes a glitchy, IDM-inspired texture. He then adds dynamic percussion and layered pads, crafting an abstract yet musical arrangement from scratch.

Recording and Arranging: Capturing the Magic

With all elements running generatively, Noah captures MIDI performances from each Pulse Engine instance into Live’s take lanes. This allows him to selectively keep, shift, or edit the most compelling phrases—blending hands-off generative output with hands-on arrangement techniques.
