Tom,

Welcome to the Showcase.

A very nice start with BIAB. Good balance in your mix - everything clear and "in a good place". Sounds good.

Stretching instrument recorded for 85 bpm to almost twice their original speed (to 140 in your case) does have a tendency to make them sound a bit busy at time (and for some instruments you might get a bit of "wobble"/artifacts - though I don;t hear that here). I imagine using instruments (RealTracks) near the tempo of your song would give you instruments that "breath" a bit more... (I understand your decision to start with the ProPak).

The video is fun to follow along with. How was that made?
