pitch output from both marbles and pams is quantized - the 2hp tune modules are superfluous

marbles contains something like a mini branches - I use both but I have a lot more - you don't need this in this size case

in this size case I would remove the mixer and one of either pams or marbles and add a quad cascading vca such as veils

I also agree with both Lugia and CM487 - in that the case is too small for more than a single voiice - and probably better used as a control skiff for a larger case

Utility modules are the dull polish that makes the shiny modules actually shine!!!
