I am confused.

I bought the RME AIO (works great)
i installed the driver, flashed the device. Works like a charm.
Then HDSPe mixer pops up, which i was kinda surprised to see, and along with it Totalmix. Who sits in my dock but doesnt really open up.
I've read through the forum and it looks like the HDSPe mixer is what originally comes with the hardware,. but then why is the totalmix included?

i hooked up the TCO and the additional Output module, easy and it works!
