On the Ketron Event , is it possible to play Style and MP3 or Midi simultaneously?

In this Youtube video by AjamSonic

titled "EVENT TUTORIAL 11 - Questions & Answers from concerned customers on KETRON EVENT Music Workstation "
a question/reply in comments was:
"Hi Can the Event synch midi and mp3 to the style.
Please demonstrate about the play list and Jude box

@AjamSonic
Yes it can. We will illustrate this in the next video soon to be released."

I have been unable to locate that video.
Does anyone know which video it is in or could they explain how this is done ?
I would really like to play back a Midi and/or MP3/WAV at the same time that a style is playing.

In the meantime, I save the Midi in a registration with the player button on. You choose the one you want and the screen switches to the Midi so it and the registration data are available.

I am just learning, so I am sure AJ has a better answer.

Hi Bernie9 ,
Thanks for replying - have you been able to get a Midi File and Style to play in Sync this way ?

No, sorry, never got into that.
