IMO, the A4 can’t do full on mayhem (or at least I haven’t found such sounds yet), but slapping distortion on top of it does miracles.
Then again, very few synths does that right out of the box, it’s more about the processing to get that sound.
This is all A4, with some distortion from a Boss KM-60 mixer. I don’t usually do this kind of stuff, I’m sure an expert in that field can do way better.
