Thanks for the feedback all. Actually had an offer from a label for this one (which I was properly chuffed about) but have turned it down due to legal stuff with sample clearance. I'm probably worrying too much but just can't be bothered with it. I turned off public downloads for the same reason, if anyone wants a copy send me a PM.
Heres what the original sample sounds like if your interested but you'll have to get digging to find the artist. I took both the piano and vocal.
Foolish Sample
Bassline was made with the free Dune CM synth. Just a couple of sine waves with a bit of a square wave thrown in. I copied the channel 3 times, used some filters to make one the sub, one the mids and the other a top end. Added a combination of different distortion plugins and fliters sweeps. Compressed it all back together in a group channel and side chained it to the kick.
I basically used Villem bass chain idea but just did it by copying the channel rather than routing it around. His is the way to go.
I'm off to try and make a track without any noticeable samples!
