I have used FMOD to create interactive music with horizontal transitions.

Each interactive music is controlled by a parameter named “Switch,” which has three regions: 1, 2, and 3. Now, I want to load this interactive music into my Unity project and call different switches in different scenes.

Additionally, I would like the interactive music to smoothly fade in and out to the corresponding segments when switching scenes. How can I achieve this?

Hi,

What version of FMOD are you using?

If the event is loaded using an [Unity Integration | Game Components - Studio Event Emitter](https://fmod.com/docs/2.02/unity/game-components.html#studio-event-emitter) you can use `StudioEventEmitter::SetParameter()` ([Unity Integration | Scripting API Reference](https://fmod.com/docs/2.02/unity/api-studioeventemitter.html#studioeventemitter_setparameter)) function to control the value of your switch variable.

To smoothly fade the music an option is modulating ([FMOD Studio | Authoring Events - Modulation](https://fmod.com/docs/2.02/studio/authoring-events.html#modulation)) the fader of each of the events using [FMOD Studio | Modulator Reference - AHDSR Modulator](https://fmod.com/docs/2.02/studio/modulator-reference.html#ahdsr-modulator).

Hope this helps!
