Loading a Transition

Loading a transition is the normal way to set up the player for a mix in Fusor Studio Plus. Picking a transition automatically loads its linked fusor and configures the player with the transition's BPM, duration in bars, and tempo ramp setting. Everything you need to be ready to arm.

You can load a transition two ways: from the transition picker in the player, or from the Transitions list view in the Library.

What "loading" means

When you load a transition, Fusor Studio applies these settings to the player:

The transition's linked fusor is loaded into the fusor picker.
The BPM value is set from the transition.
The duration in bars is set from the transition.
The Tempo Ramp toggle in the menubar's transition group is enabled or disabled to match the transition's tempo ramp setting.

The transition's outgoing and incoming tracks are not loaded into anything. Fusor Studio doesn't load tracks into your DJ app; that's still your job. The tracks linked to a transition are reference information: they tell Fusor Studio that this transition is appropriate for going from this track to that one. You load the tracks in your DJ app as you normally would.

Transitions can also carry author notes: free-text reminders from whoever created the transition, like "use red hot cues on each track as mix in/out points." Notes don't change anything in the player when the transition loads, but they're worth reading before you arm. To view the notes for the loaded transition, click the info icon next to the transition picker.

If the transition has no linked fusor, the fusor picker stays at whatever was already loaded (or empty if nothing was). You'll need to load a fusor yourself before you can arm — see Loading a fusor in the standard manual.

Deleting a fusor that's linked to one or more transitions doesn't leave broken references behind. Fusor Studio clears the link on every affected transition automatically, so those transitions simply show up as having no linked fusor on next load.

Loading from the transition picker

The transition picker is the leftmost button in the picker row.

Click the transition picker. The Library popover opens, focused on the active set list's contents (or the active crate's transitions if no set list is active).
Click the transition you want. The popover closes automatically and the transition loads.

The popover shows every transition whose outgoing and incoming tracks are both in the active crate. To see transitions involving tracks in a different crate, change which crate is active first (see below).

If a set list is active, it overrides the crate-based filter. The popover focuses on the set list's contents, in the order the set list declares, with the cursor pointing at the next transition to load. Loading the row under the cursor advances the cursor; loading any other row jumps the cursor to that position. With no active set list, the popover falls back to the active crate's transitions. See Set Lists Overview for the full set-list workflow.

Right-click the transition picker to load the next-resolved transition in the active set list directly, without opening the popover.

A hardware controller can also drive the picker through the active set list using the Next Transition and Prev Transition controller functions. See Next / Prev MIDI Bindings.

Loading from the Transitions list view

Click the Library menu in the menubar to open the Library popover. In the popover header, click Transitions. The Transitions section has five sub-tabs: Crates, Tracks, Transitions, Set Lists, and Performances. Switch to the Transitions sub-tab.
Use the search field, sort controls, and filters to narrow down to the transition you want.
Right-click the transition and choose Load.

The transition loads exactly as it would from the picker: same fusor link, same BPM, bars, and tempo ramp behavior.

Changing the active crate

The active crate controls which transitions appear in the picker. To change it:

Open the Library popover from the menubar and switch to the Crates sub-tab (under the Transitions section).
Right-click the crate you want and choose Set Active.

The transition picker will now show transitions derived from this crate. The fusor picker, separately, is filtered by the active collection (set the same way under Library → Fusors → Collections sub-tab).

Set Lists live in the same popover section, under the Set Lists sub-tab alongside Crates, Tracks, Transitions, and Performances. Activating a set list from there overrides the active crate as the picker source. See Set Lists Overview for the workflow.

When you can't load

You can't load a new transition while a transition is running. The player locks during a transition to prevent disrupting it. Once the transition completes or you abort it, loading is available again. See Transport Controls in the standard manual.

What you'll see when a transition loads

After you load a transition, you should see:

The transition picker now shows the loaded transition's name.
The fusor picker shows the linked fusor's name (or stays as it was, if the transition had no linked fusor).
The bars and BPM values in the player reflect the transition's settings.
The Tempo Ramp toggle in the menubar lights up if the transition has tempo ramp enabled.
A brief confirmation appears on the left side of the status line: "Transition loaded: [name]".
