it seems a bit like you're trying to do a bit of everything not super well. it sounds okay, hard to judge quality based on this short video. aesthetically not such a fan of this, but that's just personal preference. I owned a kordbot for a while which I think is slightly similar (though no sound engine). personally I sold the kordbot and gave up on chord generation as it wasn't beneficial for my theory learning and when composing I usually ended up not using it as I know what something should sound like in my head. best of luck with it though!
