There is a sound called “analog dark square” among the virtual instruments in the logic
Is it possible to make the sound by using “minimoog voyager old school”?
If it is possible, How should I manipulate it?
This is the second time that you ask the same question.
So if nobody answers the first time in your first topic, you can expect the same results in the second one.
better to delete the second one and bump the first. 
Can you post an audio clip of the sound your curious about emulating? Working with the title alone:
“Analog” OK, we can do that. “Dark” sounds like a function of filtering. “Square” Square wave(s), I presume. Got those.
So, yeah (probably) albeit, monophonically.
Best,
