Liking the tune mate, some people when they try and make jazzy drum & bass they get all cheesy and that but youve got it practicly spot on. I also like how it slowly progresses into a more grimier tune. Quality mate. Keep 'em comin'!
All the sounds in halfpipe dub are made from audio i recorded from my local halfpipe - i recorded stomps, grinds, pings etc., then took em home, cut em up and processed them to fuck - the bass is made by zooming far into the soundwaves until you find just one (it looked a bit saw-ish!) then setting loop-points, looping in a sampler then doing what youd do to any synth!
any other questions on the sounds i will be happy to answer matey!
glad you like peace out j
