how to check, if polyphonic voices are present in some place?
Is it possible, to chcek, if on some position is already present sounding note in other voice? 
If it is not possible, is it valid feature request?

Sorry, but I don't understand your question.
What should the "check" do?

It would be useful in automated tablature / string data creation.
If there is already used string, new tone have to be on other string.
In chord (or if notes begin at same point - second staff), it works already programatically.
But in polyphony - my example, first staff, I am not able, to make this check.

So you don't want a check between voices, but a specific check for overlapping string assignments.
A plugin should be able to perform such a feat and then for example color all such occurences.

Here is real world example.

Red notes should be on second string, as on first string is already a note "a".
But how to check, if there is that note a above them? MS UI fails on this too.
(If I am right, musescore can chceck only start points of notes.)
I can imagine, I would use internal "activeNotes" array of objects
[{"note": note, "turnOffSegment": segment},...], and go thru score and add objects and remove them on preoper place, but it seems to be overcomplicated a bit for such functionality.(for example, how to store "turnOffSegment"s? I need "next segment on track", ...)
