Is there a way of setting the fade time on getbus.setmute? I’d like to avoid a coroutine if I can, and using an ADSR doesn’t seem to work.

Hi,

To implement a smooth fade without using coroutines or ADSR, you could consider adding automation to the fader of the bus in the mixer with a slow [seek speed](https://fmod.com/docs/2.02/studio/parameters.html) applied to the parameter.

The detailed process would be listed below:

- Go to Windows \> Mixer, In the Mixing Desk, select target bus and right click to add automation to its fader’s volume.
- Create a global parameter(.e.g BusMuteIndex in this case) with initial value set to 1, add the curve to the automation of the fader’s volume and adjust the curve.

- Go to Windows\>Preset Browser, select BusMuteIndex and adjust the `Seek Speed`

- In your C# script, you could then call `RuntimeManager.StudioSystem.setParameterByName("BusMuteIndex", 0);` to smoothly mute the bus and call `RuntimeManager.StudioSystem.setParameterByName("BusMuteIndex", 1);` to smoothly unmute the bus in this case.

Hope this helps, let me know if you have any questions.

Thanks @li_fmod this is an elegant solution.
