Hey, DH - I don't even have a Steinberg program, but when I was considering a move to Nuendo, Opus told me (as did their website) that Nuendo didn't even have TrueTape. Maybe that's different in the new version, don't know.

What I do know, is analog recording. The harder you push the VU meters on an analog deck, the more you run into the natural saturation, or limitation, of the tape. Similar to digital, you can only push so far. Unlike digital, this is not a hard and fast line, and the harder you push ("saturate") the more natural tape compression results, until you finally succeed in making it sound like crap. This is the "tape" sound Steinberg and others have tried to recreate digitally. This has been used effectively on drum tracks so they sound punchier (compressed, but different) and also works pretty good on some SRV-type blues guitar tracks, anywhere you want balls. The higher you set the "saturation" control, the farther "into the red" you would be pushing the imaginary VU meters on that imaginary analog tape deck, and the more of this effect you would hear.

Bottom line is, you already nailed it when you mentioned experimenting. If I remember correctly, my buddy who uses Cubase said it was a record function, so experiments require re-recording? So, if that's true, it would take more time than just recording a track and then playing with the control until you like it, but at least you wouldn't have to clean the heads after every few passes... :=) Best I can offer from a standpoint of not knowing shit...
