The popular Flux feature has not previously been available to control via the S4 (except by manually mapping to a button of your choice) so it’s good to see that one of the redundant tempo fader mode buttons has been sacrificed for this, conveniently located just by each jogwheel. NI is a software company. To continue making money it needs to sell software to many laptop users and not limit their costumers to those who buy their hardware alone. NI STARTED as a software company, and now they’re very clearly producing hardware. Unless you consider their entire controller lineup not to be hardware. this

For those looking for intuitive, comprehensive control of Traktor, the Kontrol S4 Mk2 is hands-down your best bet for a hassle-free, plug-and-play controller that won’t let you down. The new S4 improves on what was already a fantastic controller, and the all-important control over the Traktor DJ app is spot on. When button “2” is engaged, a less enthralling EQ window slides into view which seems to just show the current values delegated by the controller, none of which are controllable by the screen; however, by tapping the Filter tab, you get an X/Y grid for the filter controls and you can have great fun using a combination of finger on the screen and knob rotations on the controller, to let rip with the filter. On USB power you simply cannot see the lights in bright daylight, but they’re just about acceptable once hooked up to the power source (which incidentally is a different power rating to the previous S4, so if you’re upgrading, your old power supply is useless). This daylight-dimness is more than made up for by the spaceship-meets-70s dancefloor appearance you get in the dark, which combined with the new aluminium jogwheel tops gives a really attractive look. It looks nice, really nice. Little touches like the slimmer fader caps and grey filter knobs in tandem with the RGB buttons and aluminium jogwheel tops have combined to give the S4 a fresh, modern look.

Important Notes

Nudge records and slow them down using the rim of the jog wheel while mixing, for an old-school turntable feel Mix your own way with versatile motorized jog wheels that transmit cue points and more direct to your fingertips I’m going to wait for traktor to release one that doesn’t need a lap top. Imagine a traktor hardware with the software integrated, kinda like the cdmp7000 but without cd’s. It might never happen but I dont see the point on spending money if it’s basically the same thing just looks nicer.
