Thanks for your feedback. The Bitbox sounds quiet interesting will definitely have a look at it. There is also the ASSIMIL8OR and the ER-301: Sound Computer, which are quiet tempting and also have a sample option. Do you have any experience with it?
"Also, I only see one VCA. That's going to bite you. It's a combo ADSR and VCA, so that's really going to bite you."
I use for one VCA the level input of my WMD PM, this somehow works, but its not the cleanest, when I trigger it straight from the hermod so another ADSR would be good. I agree with you.
LFO I send at the moment from Hermod, which can be quiet nice. I still have two doepfer lfos in my other rack but the case is too thin so they don't fit :).
"If you pull the Metropolis, I'm not sure that you'd have enough space for all of that. Perhaps a smaller main mixer?"
I will have a thought but this sounds kind of logical, the other option would be a second case :)
