SetMaster 3 v3.0.3

First public release of SetMaster 3.

Install

Download the archive for your platform, unpack it anywhere, and double-click the launcher. No Python, no Node, no terminal — each payload bundles its own CPython runtime.

Platform	File	Launch
Windows x64	SetMaster3-3.0.3-windows-x64.zip	SetMaster 3.vbs
macOS	not in this release — see below

Start/stop instructions are in READ ME FIRST.txt inside the archive. Every build also ships an isolated test instance with its own data directory and port, so you can experiment without touching your real sets.

macOS artifacts are built on macOS (the bundled CPython is an OS-specific build and the .command executable bit can't be set from Windows). They'll be added to this release once built.

What it does

• Set preparation — a structured editor for writing out a set as transition rows: track order, hot cues, EQ and level moves, timing, mix notes.
• Catalog analysis — cross-references your Traktor® collection against Spotify® playlists exported as CSV, to find what you own but haven't organized and what's on your playlists but not in your library, plus compound filtering and sorting across the whole collection.

Fully offline: a local backend and a browser UI on localhost. No cloud, no accounts, no telemetry. Your collection.nml is opened strictly read-only and never modified.

Not affiliated with Native Instruments or Spotify.

Verification

This artifact passed the repo's full acceptance check: backend suite (183 passed, 2 skipped), frontend build and unit tests, and the packaged-artifact smoke check — boots on the bundled runtime, serves the UI, idempotent relaunch, clean stop, and leaves an unrelated port owner untouched.
