so is this a single case or is it 1 of 2 - in which case - where's 2 of 2 - probably better to put them into a single case for planning!
definitely getting there though!!
one thing to watch with vcas - are they amplifiers or attenuators? check the max gain - if it is 1 then they are attenuators - a lot of them are like this - I prefer actual voltage controlled amplifiers, myself - useful for more things than attenuators - I would dump the intellijel buffered mult and get veils instead if it was me! I think you'll probably be fine with 4 vcas in this size case

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
