Introduction

Fusor Studio automates parameters such as EQ, stems, channel fader, FX, filters, and tempo over the course of a transition. It communicates with your DJ application using MIDI to control the parameters you've automated.

You can run a whole transition with Fusor Studio, or have it handle secondary parameters while you focus on what matters to you. Either way, every automated parameter is visible.

Fusor Studio is the application, and this manual covers it. It runs without a licence, in a state called Demo; a licence unlocks the full player and lets you keep the fusors you write or change. Licensing has the detail on what that does and doesn't change.

Fusor Studio Plus is an optional paid add-on that layers a library of tracks, transitions, crates, set lists, venues, and performance history on top. It shares the same player, fusors, actions, and DJ-app integration; it adds rather than changes. Plus has its own companion manual.

Fusor Studio

Nearly everything in this manual works whether or not you have a licence; what a licence changes is on the Licensing page. Plus is built on top of Fusor Studio, so every Plus user reads this manual first.

What you'll find here

The manual is organized into five sections:

  • Welcome. Introduction (this page), the vocabulary the rest of the manual uses, and what a licence changes.
  • Getting Started. How Fusor Studio works conceptually, then installation and DJ-app setup.
  • Tutorials. Nine walkthroughs you follow start to finish, from first run to authoring your own fusors and actions. Start here if you're new.
  • Manual. The subject-by-subject reference for the player, the modes, and the studio.
  • Reference. The canonical MIDI mapping, troubleshooting tables, and operational details like logging.

The split that matters is between the last three: Tutorials are sequences to follow, the Manual and Reference are subjects to look up. The same behavior appears in both, described for different purposes.

System requirements

  • Operating system: Windows 10 or later (macOS support is planned).
  • DJ software: Traktor Pro and Mixxx are Supported. djay Pro and VirtualDJ are In Progress. See the Roadmap for the live status of each app on each operating system and the gating issues behind any In Progress entry.
  • MIDI bus: a single virtual MIDI loopback port. loopMIDI is the recommended one; Windows MIDI Services with a FusorBus endpoint becomes preferred once its outstanding interoperability problem is fixed. Either choice is just a port name. Fusor Studio uses one bus in both directions, with channels 1–8 for output and 9–16 for telemetry.
  • Display: 1280×720 minimum.

Next steps

  1. Read Key Concepts and Vocabulary. Most of the rest of the manual assumes you know these terms.
  2. Walk through How It Works, Installation, and the Traktor Pro setup guide.
  3. Work through the Tutorials in order. The first two take you from a fresh install to your first transition; the last five cover authoring.
  4. Check the Roadmap if your DJ app or operating system is not Supported yet. It lists current status by app and OS, plus the specific issues each In Progress entry is gated on.

Fusor Studio Plus

Fusor Studio Plus is an optional, paid add-on, bought on top of a Fusor Studio licence rather than instead of one. Fusor Studio is still there doing what it does, and Plus surfaces appear alongside it.

What Plus adds: a library of tracks (the songs you play), transitions (pairings of two specific tracks with a fusor), crates (collections of tracks that group the transitions between them), set lists (ordered sequences for a performance), venues (locations where you perform), and performance history (the record of what you played where). The standard app keeps fusors and actions as files on disk; Plus adds searchable library structure around them.

Activating Plus

Plus is an upgrade to a Fusor Studio licence, not an alternative to one, and it activates through the same account. You buy the upgrade, sign in inside the app, and the Plus surfaces appear alongside what you already have.

The base licence's activation, and what the purchase includes, is covered in Activate Your License. What a Fusor Studio licence unlocks on its own is on the Licensing page.

The Plus manual

Plus has its own manual at docs/user-plus/. It is a delta on top of this one: it doesn't repeat anything you'll read here, only what Plus adds. The expected reading order is: finish this manual first, then open the Plus manual.
