How do you slow down Spacious theme Slider

I want to increase the speed at which the images in the featured slider are shown. I am using the free version.

I know that this is kind of old, but this is what I did:
1. Create a folder in your child theme and name it “js”
2. Copy the spacious-slider-settings.js from the parent theme’s js folder into your new child theme js folder.
3. Insert this code into your child theme’s functions.php

/* Change slider settings file */

add_action( 'wp_enqueue_scripts', 'custom_slider_settings', 100 );
function custom_slider_settings()
{
    wp_dequeue_script( 'spacious_slider', SPACIOUS_JS_URL . '/spacious-slider-setting.js', array( 'jquery_cycle' ), false, true );
    wp_deregister_script( 'spacious_slider', SPACIOUS_JS_URL . '/spacious-slider-setting.js', array( 'jquery_cycle' ), false, true );

    wp_enqueue_script( 'spacious_slider', get_stylesheet_directory_uri() . '/js/spacious-slider-setting.js', array( 'jquery_cycle' ), false, true );
}

Then you can change the timeout setting in the child theme’s spacious-slider-settings.js file to be whatever you want.

Hope this helps =)
