Hi. I am building a rack for external synths recording with PC. But I also want use it for creative music making with only an extra ipad and Blackbox while on the road. I already have several modules and some still on my wish list.

ModularGrid Rack

Left side: mainly ins and outs
Befaco in = from BlackBox - 6 output > to ES-9 for live Jam. Or from different external Synths to Ableton.
Joranalogue in = external synth recording to Blackbox or to ES-9 for AUM or Ableton
ES-9 : AUM for live jam (all IOs mixed and Fabfilter plugins on the AUM channels) or Ableton for recoding
Midi on to ES-9 to CV control external synths
Still a few unused CV outs to send CV signals from Ableton or AUM.

Right = creative section

Any suggestions to further improve the creative section?
Any suggestion about the layout (position of the modules) to reduce patch cable lengths?
Can I free up more rack space? Which modules to remove and which ones to add instead?
