I'm in agreement with @Lugia here
more modulation and more utilities needed
as Lugia said one way is to create more space by taking (imo) the top row from metopolix up to and including data plus the m303 possibly more, into a separate case - 104hp would be nice wouldn't it - too match the other cases but I wouldn't bother with a 1u row - they are imo too expensive for what they are
the other alternative is to strip out all the modulation and utilities and then work out what you really need to support what you have and is it possible to fit that it - it's quite likely that you either end up back at the extra case or having to remove a voice (simultaneously creating space for more modulation and utilities and slightly reducing the need for them)
"some of the best base-level info to remember can be found in Jim's sigfile" @Lugia
Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
