I won't add much to the beat and it overloads EXTREMELY easily, and I think that may be the reason to all of the choppiness. Please make it so it doesn't overload so easily. Thanks!
If with "overload" you mean loudness and clipping, perhaps you need to stage gain audio chains properly. If you mean glitchy playback, try these tips: (link is only visible to registered users)
