What, your ears can't tell you when something is in or out of tune? Again, if you need an oscilloscope, then you are talking about differences that don't matter.
What I see here is your assumption that every channel NEEDS an EQ and a meter. I used to EQ the krap out of everything but these days I hardly EQ anything, except acoustic stuff, like vocals and drums, that are hard to manipulate any other way.
With synth parts, I prefer to to use the on-board tools, especially the filters, to get the frequency spectrum I want. A little tweak to the resonant peak can help a part sit in a mix at least as well as EQ. And given that your mixer has functionally infinite headroom, you don't need metering at all, so the channel strips own meter is more than adequate.
I'd have to put 20 effects on every channel to get my effect count to 200. Maybe it's because I spent so much time in 16 channel studios but I honestly don't know if I could get a good mix with more than about that number of tracks/channels. All my best sounding songs use less than 10.
