How To Slow down and Pitch down like a tape machine

I am restoring a number of projects from tape and the playback speed on that tape is a bit high. So the tracks are too fast and pitched too high.

What I need is NOT "Slow down while keping the pitch the same".

I need "Slow down AND have the pitch drop by the appropriate amount."

This should be the less processor intensive and more straight forward.

It seems likes like the old school "Speed it up and it pitches up"is not even an option anymore.

Please don't tell me that I have to first render it slower and then calculate what the pitch down would be. That would create the worst artifacts from each process.
