saying that i would never actually sample a main groove or hook from somebody else's record. And actually i would think it a bit weird if somebody else did it to another record thinking about it..
duh

I myself use sample cd stuff some of the time, this is cos i like working with audio and the sound you can get from loop mashing. But alongside this i sometimes spend long periods of time making my own percussion etc loops and storing them in my library for future use. Be it with home-made loops or sample cd loops i then tend to chop and mash etc etc.. This really is a great, and can be a very creative way (depending how far you go with it) of achieving good end results (and a very 'large' sound).

Also though, i engineer a lot of other types of music where i use no loops whatsoever and work in a completly different way, with mostly synthesised parts, and i still get good results (i think). To me loop work in techno tracks is just a part of the creative process needed to attain the sound i am looking for.
