#Time macro vs metropolis ark 1 driver
Whichever driver you use, download the latest from your audio device manufacturer. Look first for the native ASIO driver that installed with your audio device OR if one is not available use the Image-Line FL Studio ASIO.
I'd suggest getting either Tundra or Neo, not both. Neo I don't have any experience with, it does look good, but again seems mostly good for quiet intimate stuff. Albion 3 Iceni is very good, but only covers the low end, and you can get by without it.
Albion 4 Uist is very specialised and I find quite hard to use. If quiet is where you want to focus, then just get Albion 5 Tundra, it is amazing for this. The rest of the Albions (beyond One) will cover quiet stuff and special interest. The only thing you won't have covered so well with Ark 1+2 is high woodwinds. I know less about Ark 4, but it looks fairly specialised still, maybe less so than Ark 3. If you just stick to Ark 1+2 especially, this is an excellent combination, and covers a lot of ground - more than the Albions. Although I'd say this is more an issue with Albion One than the other Albions. The Albions tend to focus more on ensemble patches, as says, which limit them.
Personally I think the Arks are a bit more versatile.
