What Plus Adds

Fusor Studio Plus is an optional add-on to Fusor Studio. It is not a separate application — you install the same Fusor Studio you'd install without Plus, then activate Plus on top of it. Until activation, Plus surfaces stay hidden and the app behaves exactly as the standard manual describes. After activation, the Plus features documented here appear alongside the standard ones.

For the activation flow, see Activating Plus in the standard manual's introduction.

Fusor Studio Plus extends Fusor Studio with a library — a database that catalogs the songs you play (tracks), the mixes between them (transitions), the bags you keep tracks in (crates), the ordered sets you plan or perform (set lists), the rooms you play in (venues), and the record of what you played where (performance history).

Plus does not replace anything in the standard app. The player, fusors, actions, packs, collections, palettes, hardware controllers, and DJ-app integration all work the same. Plus is purely additive: standard surfaces gain new sections and pickers, and everything that already worked still works.

Database vs files

The line that anchors everything in this manual:

Fusor Studio Plus adds a database of tracks, crates, transitions, set lists, venues, and performances. Fusors and actions stay as files on disk — the way they always have been in the standard app — and Plus adds searchable library structure around them.

In practice that means: if you're editing a fusor or an action, you're editing a file. Always. The Plus library doesn't own them. If you're working with tracks, crates, transitions, set lists, venues, or performances — anything that needs to be linked, sorted, filtered, or remembered across sessions — that lives in the Plus database.

What Plus lets you do

The things Plus makes possible that the standard app does not:

• Catalog your tracks with title, artist, BPM, key, tags, and notes; sort and filter to find what you want.
• Save a mix as a transition record between two specific tracks, with its BPM, duration, and tempo-ramp settings remembered — so the next time the same pair comes up, the right setup is one click away.
• Build a set list in advance, or build one trail-style by walking the viable next-transitions through a crate, then perform from it with a transition picker that follows the list.
• Track performances per venue automatically — every set list you complete with a venue active gets recorded, so you can see what you played at each room over time.

Who Plus is for

Plus is built for performing DJs who play the same kinds of sets at the same kinds of rooms and want to capture, refine, and re-use what works. If you've ever caught yourself thinking "I had a great transition between these two tracks last month — what BPM did I use?" or "what did I play at this venue last time?", that's the gap Plus fills.

If you're authoring fusors and testing them, or running one-off sets without a repeated context, the standard app is enough — Plus doesn't make authoring better; it makes the catalog around authoring richer.

How to read this manual

This manual is a delta on top of the standard manual. It does not repeat the standard one; it documents only what Plus adds. The expected reading order is:

1. Read the standard manual at docs/user/ end-to-end first. Almost every Plus concept builds on something defined there.
2. Then open this manual. Cross-references in the form "see Loading a fusor for the base flow" point back to the standard manual where needed; references without that ../../user/ prefix are within this Plus manual.

Start at New Concepts in Plus — the vocabulary chapter — and walk forward from there.

Where Plus shows up in the app

The surfaces Plus adds, at a glance, so you know what to look for:

• Library popover. Gains two additional sections — Transitions (with Crates / Tracks / Transitions / Set Lists / Performances sub-tabs) and Venues. The two standard sections (Fusors and Actions) are unchanged.
• Player picker row. A transition picker sits alongside the standard fusor picker and becomes the usual way to load once you have a transition library to load from.
• Status line, right side. Where the standard app shows only the telemetry indicator, Plus also shows the active venue and, when a set list is active, a coverage hint indicating how many transitions in the set list have a fusor wired up.
• MIDI bindings. Next / Prev Transition controller bindings ride alongside the standard Next / Prev Fusor bindings. See Next / Prev MIDI Bindings.
• Resume prompt at startup. If Fusor Studio closes with an active set list or in-progress performance, it offers to resume on next launch. See Resume Prompt and Edit Buffer.

Everything else — the menubar, transport buttons, mode toggles, progress strip, the studio, and the reference section — looks and behaves the way the standard manual describes.
