Well, I sure as hell don't see that balance. Frankly, this is a mess. First of all, you're overrunning the rack limits...which would tend to indicate that you should've started with a MUCH larger cab from the beginning. Plus, this is very poorly implemented; ONE envelope generator? Two buffered mults...for WHAT? And these HUGE modules...dude, this isn't a build size that can support having so many big panels. Shrink this stuff down.

Have you considered any of the following:

1) Do you know your own music well enough to specify what should go into a device to make it more optimally-suited for that music?

2) Do you know how the sounds in the music you're trying to emulate were generated in the first place?

3) Do you understand synthesis well enough to put the basic components together to do any of the first two?

Until those questions have definite, concrete answers...you're far more likely to build a boxful of expensive 'n' useless, NOT a synthesizer.

Two suggestions:

1) Get a patchable FIRST. Not only can such synths work as the core device in a modular system (sort of like what you're aiming at with the A-111-5), they also clearly show what's required for a system of your own design. And you'll discover what you can do with less superfluous junk as is here. Even a couple of simple-seeming tandemmed devices, such as a Make Noise 0-Coast/0-Ctrl pairing, would be much better for a starter than what's above.

2) VCV Rack. LEARN the basics before pulling out the Magic Plastic. VCV Rack is free, and has ample modules...some of which are even really accurate emulations of existing Eurorack hardware. Get used to using it and building up systems in it. Hang onto this rack design, then play with VCV for a few months. Then, come back to this design and re-evaluate it. I guarantee you'll be hitting "Delete Rack" fast enough to break the sound barrier! https://vcvrack.com/
