ok, thanks stryd_one
i can assure that is a couple of weeks i’m reading around the site, the wiki and the forum
but.. still i feel i know probably 0.1% about midibox… and don’t like it really 
i’ll go on reading
for what concern the project…
just let me say i’ve been djing many years, starting of course with vinyl
the i moved on final scratch 2 (stanton) and moved to NI traktor scratch as it came out
now i still dj with traktor scratch with two vinyls
some months ago i decided to leave the vinyls and technics and move just to controller
i’ve been playing (just in the studio, not in gigs) with two faderfox DX2 or a faderfox DX2 and a triggerfinger and so i came with a clear idea of what i really need to control traktor’s 4 decks (not 100% satisfied with faderfox - still djing live with scratch + vinyls)
i mean i feel what i would need, maybe this wouldn’t fit another dj requirements.
the interface should have push buttons of different sizes (big medium small) depending on how often do you use them and the kind of use: big are more performance buttons and smallers are editing buttons (allow to edit the grid, store loops and cue points etc etc)
that’s a brief introduction on the project on a more ergomonic and concept side
unfortunately the new vestax controller (400) is not satisfying as it hasn’t the controls for all the 4 decks, but requires you to swicth from A to C and B to D
Anyway, first i want to acquire some basic knowledge that allows me to buy some stuff and start practicing and see how far i can go (hopefully.. very far )
The lucky thing is i have a couple of friend helping me, one is expert with electronics, soldering and the other is good on C programming
se let’s see what’s coming out
cheers
