Yes.

Yes.

Yes.

Not to my knowledge.
Whenever you want to change the level of a signal you need an
attenuator and/or amplifier. Both CV controllable. That is a VCA.
The only thing you've to take into account is wether the signal has to
be DC coupled or not. That can become quite complex. But take your time.

Regardless if the synth is digital or analouge or whatever ;-) , it's
basically doing the same thing.

You're on the right track!

Have fun, :-) Michael.
