Let’s not forget that besides Styles,SMF's, MP3's, and Karaoke files., that we also have the option of playing full keyboard with no backing ( solo piano or vocal/piano) . Also we can mix it up more by playing LH bass ( or pedals) over a drum beat . Yes, so many options!
As for me, I mostly to do styles, because I like the flexibility of not being having to follow a prerecorded or sequenced arrangement. I use a SMF or audio backing track if I can’t find a style that suits the song or if I feel a style just can’t do the song justice. My wife who sings with me absolutely hates SMF, and any pre recorded/sequenced track, but. will give in if we feel like a style file doesn’t work.
Paul playing with others is another ballgame for sure..
many artists don't even know what an arranger is or how it works..that said..
many pro touring acts use some type of tracks
to enhance the show also..
today there are so many ways to do it, and there is
no wrong or right only
good music in whatever way shape, genre, or form it is created with.
