Freemixing takes the mash-up to its logical conclusion, which is discarding the need for complete songs altogether. Yup that's right: who needs complete tracks any more when you've got four channels, and in some software up to 16 sample players?
The big sample companies such as Loopmasters and Sample Magic have cottoned onto this already, and are making packs of loops and individual song components very much with the freemixer in mind.
Even without sample players, you can still make your own freemix on the fly with just four decks: drums, bass and a lead line with a spare deck for effects, fills and swapping parts over.
The line between DJing and production blurs even further when you think that you could be using your own beats etc that you made in the studio (ie, on your laptop) that morning. One creative flowing mix with no real start or end – mind-bending stuff!
