Hi Lucky,
sorry, I do prattle a bit.
In a nutshell,
option 1: was to cut bars from an existing style , so it may better suit the song you're playing.

option 2: was to use existing style parts, swap them round ( using copy function) to create a new style, that may better suit the song.

As for the pads, just make sure you check them out, they can add a lot to your playing.

As for me, I'm only a hobbyist.

I used to help musicians with the fundamentals of workstations , keyboards etc
sort of a walking, lots of talking,
" start up manual " back in the early 90's for one of the big Sydney music stores.

I'm basically fascinated with arranger technology , mainly style creation process.
Since I'm more technically minded, than musically blessed, I spend a lot of my time working out methods of converting styles, style editing etc etc
Unfortunately, musical creativity is something I lack. haahaa

Anyway, good luck with your keyboard hunting.

best wishes
Rikki
