In the cutting engineers lab to bring you back on topic?

That wasn't the topic. My point was that the recording can be changed at
any production stage.

And my point was that it won't be other than in the studio.

That's no distinction. It's not even correct. Even digital masters go to
mastering studios and can also be changed at the pressing plant.

Forget about the cutting engineer for a moment and pretend you're
recording direct-to-disc a la Sheffield Lab. You've decided to do an
avant-garde tape and solo instrument piece from the 60s and want to
record the tape direct and the solo instrument with microphones.

Possible?

Err, direct to disc means just that - no tape. Care to try again?

"Tape and solo instrument," remember? There's a whole genre of music for
pre-recorded tapes and live performers.

So you assemble the entire orchestra and vocals, do an identical mix
on your portable mixer, arrange for a sync output to feed all their
cans, and do your overdub.

No. You play the lp production master tape, split the output signal for
monitoring and mix the new element with the original recording before
the cutter.

The whole point of making an lp cutting master is to make sure what you
have on the master tape will cut. Adding something 'live' would be a total
nonsense. You really, really, really, don't do things like that when
making an lp. Trust me.

Refer to my earlier comment about how easy and common it is. You'd have
to really, really, really, really want to do it.

Yes it's possible. ;-)

If you say so.
