There are quite some good tape simulation VST plugins outside, but as they sound good, they sound like the plugin sound, not like my very own tape deck sounds. Sure, I could master with my very own tape deck, but then it sounds like my tape deck and not like yours, if you are playing the tune.

There is something very special, if you put the cassette into _your_ tape deck and run it.

You cannot replace this with something digital/virtual.
