Hi intheword,
I live in Germany, so my time zone is CET (= UTC+1). Currently the daylight saving time is observed, so our time is UTC+2 here.
Yes, I know this video. Basically, there are "simply" combined several standard functions (e.g. Styles, Multi Pads, changing Volumes, muting Channels) to get these results in conjunction with the "Magic Dance" Pack.
I recommend first learning to play with the internal Styles and their OTS (One Touch Settings) and the Multi Pads. Then learn to make your own Voice and Effect settings and to save all settings using the Registration Memory.
You can do all these things also with the content of the Magic Dance Pack of course. When you have some experience then, you can combine several functions as shown in the mentioned video.
By the way: It is best to download the PDF versions all user manuals (Owner's Manual, Reference Manual and Data List) from the Genos Download page and always open them at the same time on your computer. Then use the search function of your PDF reader app to find everything very quickly in the manuals.
