Ableton Live MCP server
perceivereasonact
Gives Claude the whole of Ableton Live through Live’s own object model. Observers report what you do by hand; thirty tools write into the Set with real undo.
Products, public tools and our own projects, almost all of it since Sisyphe began in 2023. Each is tagged with the layers it works hardest on: perceive, reason, act. For the two decades before, see the background.
Software for Ableton Live, for sketching and for learning.

Creative-coding framework
perceivereasonact
Sketch with agents. Sketch agents. Python on the GPU: a coding agent can look at what its sketch drew and fix it, and inside the sketch thousands of agents share one behaviour tree.

03Public2026
Learning notebook
perceivereason
A local-first notebook that teaches: the AI answers a hint or a guiding question at a time, and never runs a cell. Running the code stays the learner’s job. Formerly Pappus.

Tools and frameworks we build on, for music and for training models.

Stem separation for Ableton Live 12
perceiveact
From finished track to Live set: stems separated, drums split six ways, and loaded into your running Set through Sideman on the bar line, colour-coded and levelled.
05Open source2023–
Deep-learning framework
perceivereason
Minimal, on PyTorch: each experiment one Hydra config. Built for speech, audio and language modelling; on PyPI as slg-nimrod.
Personal pieces: an instrument, paintings in motion, a city’s cultural life, a simulator.

06Personal2026
Generative-art instrument
perceiveact
Watercolour creatures, lifted into 3D by an AI pipeline, live in an artificial ecosystem whose swarm composes the music. In the live set, the music drives the swarm back.
07Personal2022
Diffusion-animated paintings
act
Still paintings dreamed into motion with diffusion models, one artwork as the seed of each: seven pieces, from Bosch to Basquiat.

08Live2025–2026
Events aggregator
perceive
Sixty scrapers over venues, museums and community calendars on LA’s Westside, unified into one search with maps. A city as an archive, at civic scale.

09Personal2026
Simulation, sim-to-real
perceiveact
A MuJoCo simulator for things that move. Its first creature is a quadrotor that speaks MAVLink, flown headless at 30 to 60 times real time.
