I see what you mean, already had those (still have an RMX-500) and indeed more instant gratification ... Spot on from that perspective.
But found it to be limiting in the sound manipulation, presets and that is it ...
Only software had a somewhat wider selection (like traktor) on FX, but not that in to updating software (and peripherals) the whole time :-) , and worried about fails on live performance - so I prefer stand-alone units.
So in the meanwhile found one Helix (at a great discount) and started my learning curve, and indeed not that easy if your used to turning knobs and sliders as a DJ.
However, found some great advantages too, most of my music is 4/4, exp pedals can tune more parameters (at once), and in a limited range (not the full extension), with 2 send/returns (stereo).
So maybe if I need more granularity, I 'd look into the combo with MIDI.
Thanks for you honest feedback, and today I am still in the happy rush of a new purchase.
