Ketron event - Manual says - “User Audio Drum EVENT allows importing Audio files related to Live Drums, Real and Real Chords into the instrument. Given the complexity of the subject, this topic will be illustrated in details through a video tutorial that you can view on KETRON’s website at www.ketron.it . ”

I could not find the relevant video ( in English) on ketron’s website. Can Any one help- advise how to start adding user drum audio/ loops in wave or mp3 format into the user drum kits in to the Event?
Also is it possible to add the loops in its original pattern as a new user drum pattern in to the user style ARRA, B,C,D etc?
