Everything sounds like it has a got a reverb coating on it - nothing is in the mix exactly - bass is way to loose - Sound Effects are to present to me - you need to give everything room.
The adjusted Mix is pretty good - the vocals are a bit buried though - and the guitar(s) is louder - I think becuase you pulled the compression back a bit - I still think if you pulled the arpeggiated keyboard out during the verse if would stand out more - and the background vocal that is...
Like the song - and like Muse it is compressed as hell - I can’t tell if i like it or not - the Arpeggiated Keyboard part annoys me after it plays for a full minute -
it works as background to the ‘Static Bliss ‘ chorus part through - and on the fade out with the guitars - quite cool.
Cool start - I know what you mean about the slide part - it isn’t quite locking in - but at the same time I can’t hear what would lock in -
I have to think about it for a while - BTW When you hit the Bridge Chorus part you aren’t singing with the same confidence that you
did in the first part...
It seems odd that the problem is within Reaper - maybe your settings are odd for some reason - maybe. you could post Screen Shots of the Reaper Settings.
