Stemaudio

AI Music Composition Tool

A sculptor’s DAW for making long-form generative electronic and ambient music.

What It Is

Stemaudio is being built for experienced producers who know what they want to hear. Not a beginner’s tool with training wheels — a tool that gets out of your way.

Influences:

• FSOL Lifeforms
• Orbital In Sides
• Underworld dubnobasswithmyheadman
• William Basinski Disintegration Loops
• Detroit techno

The Vision

The leaf-stem-tree model: operate at multiple simultaneous scales.

• Leaf — a single parameter, a filter cutoff
• Stem — a sound object with defined duration
• Branch — a section of composition
• Tree — the whole track

Zoom between these scales fluidly. Changes at the tree level cascade down as macro-parameters.

Current Status

Session 1: Complete ✅

• Canvas UI with Dear PyGui

The Story

Michael was “Plane Recordings” — Chicago underground, 2003, vinyl. After 20 years in finance, he’s building the tool he wishes existed: for making the record between Accelerator and Lifeforms.

The machine hums. The cursor blinks. The music waits.
