Well, after a week of intensive thinking about this, I gained some clearance...
yeah , midi on the mixer is nice, but to me it appears as a distraction from the purpose of a mixer, the Eq!
The yamaha´s eq seems a bit poor for me, even the A&H zed´s eq is "poor" due to hi & low is not fully parametric.
Therefore i´d like a ML, but I don't have cash for an ML, the AD/DA & the soundcard(+ many other things that I still need like, mFX, compressor, a nice bunch of mic´s and of course synths). That would go up to 8000e / 10000$!!!
The r16 has got tree main problems to me, specially when using it as a studio-mixer for recording bands.
1- No stereo channels, having just 16 channels (dealing with stereo fx, where would I return that to?)
2- No group! I need groups for properly recording drums!!!
3- Those 60mm faders just don't convince me.
Therefore I think the right option will be a zed 428, even it has no ADAT the thing I really liked about r16

;
28 mono channels, 2 stereo, 4 groups, 6 aux & yeah, 2 Matrix!!
Even If i need 8 channel for the drums , 1 for bass, 3 for guitars,and lets say 3 for singing, I still got 13 left just in case I need them for Fx, apart from the 2 stereos...
and thats just one way to work with it that seems comfortable to me...
