3ternal, this response made a great deal of sense, I especially liked "Basically IMO a producer is defined by how well he can overcome things and translate his vision."
I mainly just don't like the idea of making music (or, if you like, creating art) using stuff supplied by other people. Sometimes when I make hip/trip-hop beats I use the J Dilla Kit, and although I didn't make the samples I treat them in a way that would arguably make them my original sounds. I guess that I'm using sounds I 'found' and creating my own things, and that's similar to recording myself hitting a bin with a hammer for example. I didn't manufacture the bin or the hammer, but I've made a significant effort to make the sounds I put in the DAW reflect the sounds in my head.
Earlier today I realised that a lot of this has to do with pride in ones work really. The more personal importance you give your projects the more uncomfortable you might feel using loops that have already been produced and perfected by other people, and it might feel like cheating. All I can say is there's nothing like producing an astonishingly good track from the ground up, having done everything by yourself. That's why I will always discourage the use of loops.
It's only humans in the first place that created loops, so other humans should be able to learn how to make similar things.
