Thanks for the feedback.
Now that I'm looking at it - you're right. I did have everything arbitrarily slotted into place without a thought for workflow, and it seems much better with that layout. Also, the addition of more envelope & VCA is a wiser choice in the end. I do have some personal thoughts on it though...
So I understand your removal of the uScale, since the Metropolis does it's own quantizing, but now I'm beginning to think I should forego the Metropolis altogether for something that's more of a brain / control centre, like a Hermod -- hear me out. What I enjoy and find most exciting about the uScale is using the shift function to switch between my pre-programmed scales and emulate 'chord' changes, and from what I've read, this is something the Metropolis doesn't do well without feeling clunky and rigid. Hermod might not be any better (I'm still reading about it), but my first impression tells me that it would facilitate those changes a lot easier.
