You can control the speed by changing default values in the file framework/functions/slider-shortcodes.php. Check the function mo_responsive_slider_shortcode() at line numbers 7 and 8 to control animation speed and slideshow speed. Let me know if you still face issues. Thanks
Ok. Actually that would change the defaults for all sliders. You can change the values for each of the sliders by inserting the attributes slideshow_speed and animation_speed into the shortcode.
If you need to control speed for only the slider post, try to put insert shortcode attributes slideshow_speed and animation_speed to the slider post. You can accomplish this by editing the file single.php in theme folder at line number 48 from
