so this is a section for train wreck mixes and bad tecnique ?
doesn't sound like a good idea to me, sureley the aim of creating a mix is to showcase good music in a natty style, wether it be beatmatched with vynyl, jammed up with machines, done using final scratch/ableton/whatever.
Are you seriously proposing having a section to post naff mixes that weren't good enough to post in the mixes section ?
eh ?
why not just post them in the mix section - If they aren't good enough, why are they being posted ?
Have some confidence, If you don't like ur mixing - your wasting your time and should stick to entertaining friends when they drop by for a beer.
I really don't want to be rude but surely the interet is full of half assed attempt at stuff as it is, bad quality control mean all the decent stuff is often overshadowed, so why should we waste time litening to substandard stuff when there is so much good stuff about ?
If you wanna compare tecnique etc - make some cds and swap em or yousendit to folk, no point in drawing mass attention to it, it's like - look mommy - I made a poo poo
Maybe I've misunderstood, if so - I apolagise, but I really can't see the point in this at all.
etc. but not that fast and maybe not that accurately as your Mac does.
