If you read some recording articles, no one they say should record at 0 db level anyway, and on a computer you add everytime you add another track so the volume goes up and into the red. The way to record is always lower like between -9 dB and -6 dB on the DAW's VU meter. In other words the input coming into your analog equipment may be going up to 0dB but the output (going out to the Babyface) should be able to be adjusted to output into an audio/interface unit lower so the signal is loud enough not to have noise in it, but not too loud as to distort a digital recording which is easier to do than with analog.

The inputs into my Babyface are automatic, the TotalMixFX program just reflects what the signal is that is coming into the Babyface.

But perhaps someone else can explain it better if not understanding.
Digital is different than Analog.

When digital goes over 0 on the vu meter, it wrecks the recording - up to 0 on the VU meter, not over. On analog equipment, you can go over 0 on the VU meter, but a computer can not go over 0 on the meter. (only up to) - but some equipment is better than others even in digital if you want to spend several thousand perhaps 10s of thousands of dollars on such equipment.
