Just picked up a DDJ-1000. Amazing in really forward looking ways but I'm surprised there's no default/elegant way to do something as fundamental as preview tracks in the browser without constantly touching the laptop.
A primary reason for me to buy such a significant controller with screens was to reduce excessive interactions with a laptop. (especially any that make me look like I'm constantly jumping on facebook mid-performance)
I hear you can map midi to start a preview. Could I map this to shift + load knob. Shift + Click in the load knob to start the preview and scrolling it back and forth while shift is still held down scrubs through it.
If that's not possible I think an official option for preview start + scrub back and forth somewhere on the controller is much needed. Thats the only thing I really miss from my Kontrol hardware.
I think the mapping method outlined above would represent pretty low risk of screwing up an active playing deck as long as load lock was enabled.
