Thanks for the feedback! The tremolo is a feature in the plugin I'm using, so I'm going to have to add more (to a lot of) automation to turn the tremolo on and off at certain points, then.
When you say chords, I do hope you mean actual chords, and not individual notes. Although, someone asked me to make the Bass more dominant and dynamic, so... I'm just going to lower it just a bit so that it will blend in more but not too much.
