Engadget: Look, last year’s Traktor Kontrol S4 was pretty damn awesome but, at $1,000 and about the size of your average Williamsburg DJ, it wasn’t exactly for everyone. That’s where the S2 comes in. Instead of four channels, it’s a “2+1″ setup that supplements the two standard audio ones with a dedicated sample channel. You still get the same high-resolution jog wheels and integrated 24bit / 96kHz sound card, but Native Instruments managed to shave a few inches, pounds and bucks off its predecessor. At $669 it’s much more affordable — still not exactly an impulse purchase, but within the range of most serious hobbyists.
