i've been using final scratch a bit recently and i have to say i love it.
but mainly because i produce and i just want to play my stuff out a bit sooner. also you have so many options open to you if you are actively involved in music making.

ie: personalised bootlegs , exclusive remixes etc
it could be viewed as being an alternative to a live set.

obviously there is the risk of people downloading trax and never buying vinyl
but they'll do that anyway and play it off cd, so what's the difference?

it's a good program which is getting better with the new updates
and the possiblities are endless, so it aint dead yet.

also i'm finding more and more clubs have it installed
which means you don't have to do that unplugging thing with the dex , which is its greatest drawback i.m.o.
youm can just jack straight into the usb of your laptop and away you go

anyways as .d.o.a.s. said
we've had enough threads about f.s.
maybe if you need to know more go back and check some earlier posts.

anyone who wants to talk about f.s. is welcome to pm me
