Licensing

Fusor Studio downloads as an unlicensed Demo. Demo is for evaluation: it loads and runs any fusor on disk, including a file someone sent you, with no session limit.

Demo is also how you study a fusor you did not write. Run the file and watch the parameters modulate across the transition. The author's timing is visible in the player while the run is under way.

Actions are free at every licence level. Writing, loading, binding to pad slots and firing all work in Demo. See Pad Mode.

Demo limitations

A licence lifts every limit below. Everything else this manual describes works unlicensed: the player window, arming and running, starting, pausing and aborting, Blind Mode, the DJ-app setup, hardware controllers, and the whole of the reference section.

Demo cannot keep a fusor

You can open any fusor and its domain editor, drag anchors and watch the curve respond, add and remove domains, and edit the details. The change is live for the rest of the session: load the fusor and it runs the way you just changed it.

What Demo cannot do is write to disk. Four verbs are licensed: creating a fusor, duplicating one, deleting one, and saving any change. The New Fusor button is greyed, Duplicate and Delete are absent from the right-click menu, and an edit is discarded when you leave the fusor or close the editor. A blue Demo notice on the fusor detail view and on the domain editor says so, and each notice has an Upgrade button.

Your Notes is a field inside the fusor file, so a note falls under the same rule.

See Authoring Overview for what the authoring surface is, and Author Your First Fusor for the walkthrough.

Demo runs every transition in Auto Run Mode

Manual Run Mode is unavailable. The Auto/Manual toggle is greyed, a Demo player always opens in Auto, and the clock drives progress from the first bar to the last.

Grabbing the crossfader mid-transition does not take progress off the clock. Fusor Studio goes on asserting the fader, so the fader springs back on the next tick. The status line reads "Demo: crossfader stays automated" so that the spring-back is not read as a MIDI fault. Progress does not follow your hand and the transition carries on.

Taking a single automated control still works, at every licence level. Move an EQ knob or a deck fader during a run and that control is released from automation until the transition ends. Demo's refusal covers progress authority alone.

Demo runs left deck to right deck

The left deck is always outgoing and the right deck always incoming. Roles do not swap when the transition completes, and the manual role swap is refused. A second run is therefore also left to right, so you re-cue your decks between runs.

Arming parks your crossfader at the left. A transition needs the fader's full width to travel, and a completed run leaves it at the right-hand end, so the park puts it back at the start.

Length is fixed at 16 bars

The bars field shows 16 and cannot be changed in Demo. BPM stays editable at every licence level: changing it changes the computed duration, so a Demo run can be matched to the tempo of the material you are demonstrating.

Activating a licence

Activation happens inside Fusor Studio and works by signing in to the account you bought the licence with. There are no licence keys to keep.

The mechanics, including what you need a connection for and how many computers a licence covers, are in Activate Your License.

Fusor Studio Plus is activated separately, on the same account, and is bought on top of a Fusor Studio licence rather than instead of one. See Activating Plus.
