You're welcome, I'm glad that you found the thoughts helpful!

There are two main things I would address with the latest iteration of your rack, and they are both related to the percussion modules, some of which you already mentioned in your last paragraph:

1. There is still a deficiency of mixing capacity present for the percussion modules if you intend to use all of them at the same time as the Vhikk X and Oneiroi. In order to use all four percussion modules simultaneously, you would be occupying all four channels of your stereo mixer, leaving no room to use the other voices. You could use the four channels of the Quad VCA as a mixer, but then you miss out on having the VCAs there for creative modulation purposes. You will probably want to add a four-channel mono audio mixer in there, at the least. Or more VCAs.
2. Those percussion modules are so small and tightly packed that it's going to be a struggle to enjoy using them. And trying to use them in any sort of live application is likely going to be frustrating, unless you intend to never make any adjustments to their knobs. Notice how the other modules are designed with more space between the knobs and jacks, and even some of those are tight and not the most ergonomic.

My recommendation could go two ways:

1. If you are set on having a kit-worth of percussion modules in your rack, I would recommend going back to the original WMD ones and adding at least 50% more rack space. But really I think you would be better off doubling it, either as a case that is twice as big or a second one of equal size.
2. Take the percussion duties out of this rack and go with an external drum machine. For the same cost as the trigger sequencer and miniature percussion modules in the latest rack iteration, you could get someting much more practical, user-friendly, and capable for percussion duties.

I hope those critiques don't come off as too harsh, but I think they are valuable things to consider.

I hope some of that is helpful again!
