That’s where the arranger player needs to get more involved when it comes to style repetitiveness. If you want to avoid that issue, then you have to dig in and edit the variations. It can get repetitive on a workstation as well. If you create your own backing tracks and chain those patterns in a more traditional way (intro/variations/fills/ending), it can be just as repetitive. The arrangers giveaway will always be the bass track. If you want your arranger compositions to really open up, delete the bass track from a style, and record it manually, and linear. Auto Accomp will always sound “auto” due to programming limitations so various parts work with chord recognition.

Get yourself a stand, pedalboard and expression pedal and you wont need all the easy play features of an arranger that make it boring and repetitive, plus if you play live people will know you are playing the instrument rather than just pressing buttons karaoke style. (The only downside is that you loose the press a button and everything is done for you of an arranger, but this is compensated for as it is way more satisfying to play the parts yourself)
