Help me fix the strumming

[Alyctro]

Hi, i have a strumming problem with the new engine. It sounds very repetetive. And i have tried every obvious setting there is. I'm sorry if this post sounds very vague but i'm a new user (with restrictions).
I can try providing you with a visual and audio example. I tried the strumming mode, the prerecorded power chords, manual power chords. It sounds like only two notes are alternating.
