How It Works
A fusor holds a transition effect you author ahead of time. It specifies how each parameter it modulates (EQ, stems, levels and effects) changes as the transition progresses from 0% to 100%. The Fusor player runs the fusor and sends each value to your DJ application as MIDI. Progress through the transition comes from your hand on the crossfader or from a bar count at the BPM you set. The vocabulary used here (fusor, deck role, progress, the three Run Modes) is defined in Key Concepts.
The Fusor player controls your DJ application the way a hardware controller in MIDI mode does. It exchanges MIDI with the application over a virtual MIDI bus that runs in both directions: the player sends to the application and receives from it, and monitoring and control state capture use the MIDI it receives.
A fusor modulates parameters inside your DJ app: EQ, stems, levels and effects. Fusor Studio cannot control an external hardware mixer, so your DJ app must use its internal mixer.
Progress is shown by the position of the crossfader, so moving the crossfader advances the transition. That is Manual Run Mode: the transition advances at the rate you move the crossfader.
Auto Run Mode derives the duration from the bars and the BPM you set. Sixteen bars at 120 BPM is exactly 32 seconds, and the transition runs to that length on the clock.
Mixed Run Mode runs on the clock up to the fusor's mix point, then stops and follows the crossfader to the end.
When the transition ends, settings in the fusor determine what happens to the outgoing deck's controls it modulated: they hold where the transition left them, return to where they started, or go to their home position. See End of run.
