Cheers for feedback peeps, all very constructive and useful.

Been a bit lazy with percussion patterns, fair point. Wanted simple loops and the progression to come from the filtering and effects layered onto them, but I could definitely have more pattern changes and development.

Tried playing around with harmonic elements without much success. Kinda like it as it is... harmonic elements change the feel of the track in a way I don't like. Maybe just haven't found the right way of doing it though.

Rory - does the synth really sound weak to you? Its sounds massive on everything i've played it on, and my mackie's rarely lie... bit worried if it sounds weak, its as brassy as I can really get away with and its been a ****er to mix as it is...

ta' muchly for listening
