I said it was stereo because, when I record with it, the rsulting .wav file is
2-channel.  Then I concluded it was stereo.

What I want is, say, 4 different mono channels.  For example, if it's a string
quartet, each instrument should have its own microphone and the resulting track
should be mono.  If it is a piano record, I want two microphones, one for
mid-trebles and one for mid-bass, 2 mono channels.  If it's voice and piano, I
want 3 mono channels and so on.  Do you think it'll be all right with the
Behringer UMC404HD and that microphone of mine plus adapter?  That microphone
is nice for its lightness too.

What do you mean please by differentiation?
