Your objective seems to be to create sample-based music, using your jazz library.  Therefore I would suspect the above is not the best buy, as it is for DJing, albeit with lots of creative options.  (If you're hoping to get into DJing, you'd be better off using a laptop or vinyl.)  I know several people who make electronic music, and none of them use a DJing set up for anything other than DJing.

There must be a forum for people making music - they should be able to give you the best options, but it's software that you need.  And vast amounts of time.

heppie - just download AUDACITY - its free and you can sample and then mix to your little frozen faux cloggie hearts content. Or do what I do make phone tones from obscure riffs or well known ones and load them on your phone.

As an example that silliness has no boundaries I have sampled Dandy Livingstone so that my phone when it has an SMS/TXT for me sings the phrase "Message for you"

Play what you format you like Cat. But not in a club, if your not going to buy the "real" deal, FFS don't insult the artist and buy boots. And don't spin of a laptop in a club unless it's modern. Other fans of an older genre will think your a hoho and you'll never get gigs outside your local wine bar, let alone pack a night of your own.

This is the future:

Combined with the Live software, this is exactly what I need!
