Thanks for the feedback and some helpful food for thought
I guess one of the other things I am aware of is that as I am still new to this I don't want to overwhelm myself with things - would you think it may be better to simplify this rack idea - and what would you take out/put in? I could lose the FR Transient Plus and although the Morphagene looks fun, it isn't necessary.
As I say I started with the Erica Synths System 2 as a starting point but wanted to add some additional bits to go with it. I thought the Make Noise B&G system looked good but for some reason the demos didn't really do much for me in terms of the sounds coming out.
For the utility modules, is there any you would recommend that aesthetically look nice but are also relatively simple for a beginner?
