Introduction

Fusor Studio is built around its fusor authoring system. You author how parameters such as EQ, stems, levels and effects modulate across a transition, save it as a fusor, and run it as often as you like to hear how it sounds. The Fusor player runs the fusor and sends each value to your DJ application as MIDI, the same way a hardware controller does.

A fusor can shape a whole transition or a single parameter. As the transition progresses, from your hand on the crossfader or a bar count you set, the player modulates each parameter you've authored. Move any of those controls yourself during a run and the player stops modulating it for the rest of the transition.

When you download the Fusor Studio installer, you are downloading Fusor Studio Lite, free and with no account. Lite runs every fusor on a bar count, so you can watch and listen to any technique as its author built it. Lite has no time limit, runs any fusor as many times as you like, and includes the full Action editor and execution engine. Lite is limited in three respects: all transitions run on a timer, the timer is fixed to run transitions across 16 bars, and making or changing fusors needs a license. See Licensing for additional detail.

What you can use it for

Developing techniques

Author a technique as a fusor and run it on your own tracks. Duplicate it, change one curve, and run both to hear the difference. Run the same fusor across different tracks and genres to hear where the technique holds up.

Practicing

Use a fusor as a baseline to practice against. Change the pace across several runs and listen to how each change sounds, without your attention split between the sound and what your hands are doing. Settle the overall timing first, then work on the specifics.

Recording

For a mixtape, a mix to share online, or background music for a video, author the effect layers of a transition (stems and effects) and drive them from the crossfader as you record. Your hand sets the timing, and the parameters you've authored modulate in step with it on every take.

Teaching

A fusor shows a technique as it runs: which parameters move, when, and by how much. A student can open the same file and run it on their own tracks.

Fusor Studio Lite is enough for a student. It runs every transition on a timer at a fixed 16 bars, opens a fusor's curves to read, and needs no license and no account. Making or changing fusors needs a license.

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 license changes.
• Getting Started. How Fusor Studio works conceptually, then installation and DJ-app setup.
• Tutorials. Walkthroughs you follow start to finish, in order. They are written for the licensed player, so activate your 14-day Free Trial before you start them. Setup, the first tutorial, ends with the steps. Start here if you're new.
• Manual. The subject-by-subject reference for the Fusor player, the modes, and the studio.
• Reference. The canonical MIDI mapping, troubleshooting tables, and operational details like logging.

System requirements

The roadmap lists which DJ applications are supported on Windows and on macOS.

Fusor Studio needs a virtual MIDI Bus to exchange MIDI with your DJ application. Guided Setup walks you through creating the bus and configuring Fusor Studio for your DJ app.

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, Connect Your DJ App, and the Traktor Pro setup guide.
3. Work through the Tutorials in order. They run from a fresh install to authoring fusors of your own, and are written for a licensed player.
4. Check the Roadmap for the status of your DJ app and operating system. It lists current status by app and OS, with a short note on each app.
