The playlist of Genos was made to make things more easier, like song selecting and managing, grouping.
IMO is easier to make a playlist with some songs you play instead of searching for some registrations in thousands of registrations banks.
Indeed, there are some improvements they have to make to Playlist function in Genos, but as it is now it works very well, and in my opinion it is useful.
Of course, there are several ways you could change/select songs/styles to play, but the easiest way is the one you're used to, which you use day by day.
For example, some people use one registration bank for a song, and put their first registry as main registry, which select the style or midi file, and the other 9 registry has some other functions set, change voices, settings for harmony, splitting point for some dual voice solo instrument parts, etc. Some other people use one registry from registration memory bank per song, as they no need to change for other instruments/voices, or change voice harmony, etc, so it is enough one registration per song. The second way is the one I use, because I sing in a band, with more acoustic instruments, so I don't need to make some solo interventions, because they do.
It's good that Yamaha has let us use registrations as we want.
The playlist is in addition, is to help us choose quickly registration banks or to automatically load registrations from registration memory banks and to auto-display some of viewers.
So, with one single touch you have : Registration bank select from thousands of registration bank files (a lot of pages to search for), registration memory from 1 to 10 auto load, and Lyrics/Text/Score automatically display on the screen. One touch for all of this! What do you want more?!
I think they have created a very good way to manage registration banks.
