Nested Tuplets and Containerised Rhythms in Live with MIDI Tools

Discover how nested tuplets and containerised rhythms can transform your MIDI composition workflow in Live. Philip Meyer walks through his Blocks and Divs tools for building generative, evolving beats.

Building Complex, Organic Rhythms with Blocks and Divs in Ableton Live

Philip Meyer returns with a deep exploration into the rhythmic world of nested tuplets — breaking away from traditional grids and diving into multi-layered rhythmic structures using his custom MIDI Tools for Ableton Live. Starting from the concept of rhythm as a containerised structure rather than a rigid step-sequencer grid, this walkthrough showcases how to use Blocks and Divs to create evolving, nuanced rhythmic patterns that feel both precise and human.

What Are Nested Tuplets?

The idea originates from composers and developers at Cycling ’74 with the Nestup device, where rhythms are built by recursively subdividing time segments. Instead of placing notes on a fixed grid, you create “containers” of time and divide them into uneven or variable segments — resulting in expressive, non-linear timing.

From Max to MIDI: Reimagining Time

Initially implemented in Max using signal timing, Meyer later ported the approach to MIDI within Ableton Live. His tools, Blocks and Divs, offer hands-on control over these nested divisions. Blocks create the primary time containers, while Divs subdivide them independently — unlocking a wide range of rhythmic textures, from strict repetition to intricate polymetric phrasing.

Building Rhythms with Blocks and Divs

In this video, Meyer demonstrates:

• Setting up basic container divisions with Blocks
• Subdividing using Divs for layered tuplets
• Using velocity decay and quantisation for expressive timing
• Desynchronising subdivisions to create phasing effects over longer bars

Each container can be manipulated independently, and the layering of divisions leads to rhythms that evolve unpredictably while maintaining an internal logic.

Advanced Techniques and Variations

By duplicating containers or offsetting division patterns, you can break uniformity and create grooves that unfold across bars. Tools like Segment allow selective transformation based on note length, while adding velocity modulation and feel shifts injects a humanised imperfection.

Meyer even proposes an ideal future for Live — transformation chains where clip edits could propagate across processing stages, enabling a non-destructive, modular approach to rhythm creation.

A New Workflow for Rhythmic Composition

Meyer’s MIDI Tools are designed to work best in combination: generate, transform, duplicate, and remix. Save multiple variations as clips and use follow actions to arrange evolving structures, making the tools perfect for generative, improvised, or performance-ready material.
