Bachus the whole idea was to play Beatles songs with NON specific song styles there are so many already out there on these keyboards .....
this is where the creativeness comes in.
For example try "I Am The Walrus" using a Slow Waltz,
or maybe "The Fool on the Hill" with a Bossa Nova styles etc, ...
would love to hear something like that on your Jupiter etc..
Thats what i do allthe time..
However another topic here pulled my journey recently to song specific styles...
It was the organ player withthe lowrey...
Both ways are fun, and require a totally different approach..
With one you addapt your style to the song
Withthe other you adapt your plaing to the style
