This is my current minimalistic setup.
Analog four mk2, Analog Rtym mk2, small Arturia Rackbrute with a Mutable Instruments Clouds clone. I think i’m going to fill it up with a Moog Mother 32, just to occupy the remaining rack space and don’t fall into modular g.a.s. ;))
Everything goes into the Behringer x18 “mixer” (AR/A4 individual outputs into it’s 16inputs) which is under the table, so all the cables are hidden.
The mixer, beside allowing latency-free jamming (and sounding great, despite being Behringer 
) is an audio interface as well, which allows every kind of routing (a4/ar effects, clouds…) and i’m using it to feed some channels from/to the ipad for ios plug-ins/effects/softsynths. The Expression Touché controls the Performane modes of the Elektrons and the clouds via CV (quite cool) 
The Behringer X-touch is a bit of a plastic toy but it controls the mixer ‘hands on’ without the need of using the dedicated ipad mixer app and the mini colorcoded scribble-displays are very usefull (and the motorized faders for the scenes as well)
I still call it daw-less, because there is no daw involved and i don’t consider the ipad a computer, but rather a tool which can do tons of cool stuff. With the xkey37 i play the ipad synts and record live into the Elektron’s sequencers
Therefore i will go down your suggested route (or a similar one) for sure. Thank for your time
