Traktor QML Mods (Documentation)

Handbook Version: v1.1.0

This repo is a documentation set for customizing Native Instruments Traktor Pro using QML — the language Traktor uses for its controller UI. If you've created MIDI mappings in Traktor Pro, you understand the concept of wiring hardware controls to actions. QML works the same way — it's just more powerful: you can change what buttons do, what screens show, and how the UI behaves.

Note: The traktor-mod scripts referenced in this documentation are vibe-coded via AI with minimal code review. Use with caution and review scripts before production use.

Setup: Companion Repositories

Clone these two repositories alongside this handbook:

git clone https://github.com/lsmith77/traktor-kontrol-qml-files
git clone https://github.com/lsmith77/traktor-logger
  • traktor-kontrol-qml-files/ — stock Traktor QML baseline, used by AI tools for comparison
  • traktor-logger/ — real-time debugging dashboard (required for traktor-mod logger commands)

Using this handbook as an Agent Skill

This repo ships a SKILL.md at the root, so any AI agent that supports the Skills format can load the handbook on demand. Install it as a skill (or drop the repo into a directory the agent can read) and ask Traktor QML questions — the agent will pull the relevant chapters and prompt templates itself instead of you having to paste them in.

I want to install a community mod

  1. Chapter 03: Community Resources — curated list of GitHub repos and forum mods for S4 MK3, X1 MK3, and other controllers
  2. Chapter 01: Basics — qml folder structure, Traktor architecture
  3. Chapter 08: Sharing Changes — traktor-mod script setup (automates backup, overlay install, restore); if the script fails, scripts/manual-install.md covers every step manually
  4. Chapter 05: FAQ — safety, Traktor updates overwriting mods, common questions
  5. Chapter 04: Troubleshooting — when something breaks

I want to combine features from multiple mods

  1. Chapter 10: Prompt Templates — full index with workflow order
  2. Chapter 11: Combining Mods — Complete Workflow — step-by-step guide (preparation → AI generation → save → deploy)
  3. Chapter 08: Sharing Changes — understand mod structure before combining
  4. Chapter 09: Mod Documentation Guide — how to read feature documentation in well-documented mods
  5. traktor-logger — verify combined mods load and interact correctly

Paste the prompt into Claude, ChatGPT, Copilot, or any AI chat — no tooling beyond a text editor and git.

I want to create a custom feature

Example: "Pressing PLAY while the deck is playing should trigger a 700ms vinyl brake ramp, then stop."

  1. Prompt Template: Create Feature — copy the template into Claude, ChatGPT, or Copilot
  2. Answer a few questions about your feature (trigger, behavior, configuration)
  3. Get complete QML code + documentation + test checklist
  4. Deploy and test in Traktor — use traktor-logger for real-time monitoring

See Chapter 10: Prompt Templates for details, or jump straight to prompts/create-feature.md.

I'm a new mod author

  1. Chapter 01: Basics — QML fundamentals, folder structure, how Traktor loads files
  2. Chapter 02: API Reference — control value paths, copy-paste code patterns
  3. Chapter 08: Sharing Changes — how to package and publish your work
  4. Chapter 09: Mod Documentation Guide — how to structure your mod so users can apply individual features, and so AI tools can combine your mod with others automatically
  5. traktor-logger — test and debug your code with real-time monitoring

The format in Chapter 09 — one markdown file per feature, semantic version tags in git — means your users can pick just the features they want, and understand exactly what changed in each release.

I have an existing mod and want to adopt these conventions

Two changes make your mod compatible:

1. Use git and semantic version tags — tag your releases (v1.2.3). Users can run git diff v1.2.2..v1.2.3 to see exactly what changed.

2. One feature = one markdown file — document each feature alongside your QML:

your-mod/
  features/
    vinyl-break.md       ← what it does, files changed, before/after code
    loop-roll.md
    screen-display.md
  qml/
    ...

Each file lists: what the feature does, which QML files it touches, settings/toggles, and a 3-step test checklist.

→ Chapter 09: Mod Documentation Guide — full format spec, real examples, pitfalls to avoid, and the reasoning behind each convention
