New Concepts in Plus

This chapter introduces the terms Fusor Studio Plus adds on top of the standard manual's Key Concepts and Vocabulary. Every term here corresponds to a database entity: tracks, transitions, crates, set lists, venues, and performance history all live in the Plus library. If a term isn't listed here, it's standard — look it up in the standard glossary.

What you work with

Track

A song. Tracks are stored in the library with title, artist, BPM, key, tags, and other metadata; you can sort and filter by any of these. Fusor Studio does not play tracks — your DJ app does. Tracks in Fusor Studio's library are records about songs, used to organize transitions and set lists.

Transition

A record of how to mix from one specific track to another. A transition links an outgoing track, an incoming track, and a fusor that drives the transition, plus settings like BPM, duration in bars, and whether tempo ramp is enabled. Transitions are stored in Fusor Studio's library database.

A transition is not the same thing as a fusor. The fusor is the reusable recipe; the transition is "use this recipe to go from track A to track B at this BPM for this many bars." Many transitions can use the same fusor.

Transitions can also carry author notes: free-text reminders from the author for use at performance time, like "use red hot cues on each track as mix points."

The word transition also gets used in standard contexts to mean the act of mixing — the live 0%→100% progress run. The Plus database entity above is a stored record of how to mix a specific pair of tracks. Same word, two senses; usually clear from context.

How things are grouped

These additional grouping types extend the standard glossary's set (Collection, Pack, Palette). All grouping types coexist; they don't overlap.

Crate

A named, unordered group of tracks. Crates are how you organize tracks for a set, for example "House Friday Night" or "Warm-up Set." Transitions appear in a crate by derivation: any transition whose outgoing and incoming tracks are both in the crate is part of that crate's transition pool.

Set List

An ordered sequence of tracks, used for performance planning and tracking. Where a crate is an unordered pool, a set list lays out the order you plan (or played) the tracks in. Set lists support both forward-planning workflows (build the whole list in advance) and on-the-fly workflows (start from one track and follow a breadcrumb trail of viable next-transitions through the crate).

When a set list is active, it overrides the active crate as the source of the transition picker: the picker shows only the transitions referenced by the active set list, in the order the set list declares. Make a set list active by right-clicking it in the Set Lists sub-tab and choosing Activate; with no active set list, the picker falls back to transitions derived from the active crate.

An active set list can also be edited in place during a performance without losing your cursor position. See Set Lists Overview for activation, Resume Prompt and Edit Buffer for the edit-mode workflow, and The Set List Builder for building one trail-style.

Venues and performance history

Venue

A named location where you perform. The active venue is shown in the bottom right of the status line as a display indicator (the status-line venue area is read-only — clicking it does nothing). When a venue is active, Fusor Studio records performance history against it: which tracks were played, when, in what order. With no active venue, no history is recorded, which is what you want when prepping a set or practicing. To pick or activate a venue, open the Library popover from the menubar and switch to the Venues section.

Performance History

The per-venue record of which tracks have been played, when, and in what order. Recorded automatically while a venue is active. Used to plan future sets (see what was played at a venue last time) and to track playback over time.

Past set-list performances can be reviewed in the Performances sub-tab inside the Library popover's Transitions section (it sits alongside Crates, Tracks, Transitions, and Set Lists). Each row shows the set list, venue, played/total counts, and when it happened; right-click a row to clone the source set list or jump to it. See Reviewing Past Performances.
