You don't say what model of keyboard.
The main attraction of an arranger is the styles, so if you don't like any, well maybe this isn't the brand for you ...
On the S- series, Tyros and Genos you can make your own styles or remix any of the preset ones (change volumes, voices, stereo pan, mix and match between styles, reprogram any parts)
It's easy to create a style, but creating a good one is not so easy.
