KS4 alternative...

[djpbe]

I was thinking about mapping the pitch faders to fade from deck a to deck c, and deck b to deck d. I don't tend to use them anyway, and it would let me use my 2 channel mixer. I don't know if it will work, but I only use two decks most of the time. I really just think I need two units cause I will forget what layer I'm on.

I'm also considering this alternative, but with a DX 1100 mixer.. (i already have 2 turntables and 2 cd players i want to use with TSP)

It really depends on how well the SC2000 work with traktor. if it's as precise as the S4 it might be a better set-up (more flexible, more buttons to map, more transportable)
