Thanks, these are really great suggestions, I went back and incorporated some of them.
I’ve uploaded the re-edit here: remix
I decided to go very aggressive with a filter on the master track, with a square wave LFO so the depth is either 0 or 1. And a filter on one of the melody parts at some stage.
I added a few more slices of the sample in too. Thats something I’m working on though, seamlessly and carefully blending in samples so they don’t stick out like a sore thumb.
Overall I think the result is a more interesting track. A bit busy at times maybe though.
