the racksize is much to small -
you need space for utilities
Better dont start under 104 hp 6u
Dual fx is not so cool for ambient stuff in my opinion
check out qubit and bastl, make noise and intellijel
what about a sequencer, sample and hold, lfo, envelopes, attenuverter....
bastl neo trinity has much of these in 8 hp with 6 outputs - for small systems
drop the dual fx, scales, mixup and talin
Here is a suggestion to start:
Later you could add a matrix mixer and more stuff in the empty top row .....
