Universal Audio has two native tape emulation plugins, the Oxide and Studer A800. The Oxide is a basic, easy to use tape recorder with only a few adjustable parameters. The A800 is a full reproduction of the entire multitrack recorder with tape type, speed, etc., available for tweaking. There are also UAD2 versions of the plugins for ultra low latency while tracking through a UA Apollo.
I use a lot of my UAD2 plugins with my Apollo X6 with my Kemper rack. The two make a killer combination.
