The strings sort of jump in and don't fit it with the mix - they sound like they're synthetic and coming in from nowhere, instead of being in the same place as the rest of the instruments.
David, I noticed this too. The strings (and the vibraphone) are coming from my Korg keyboard and my fingers on that keyboard. You didn't mention the vibraphone, so to you is that "coming in from nowhere" too?
What if the strings were in from the beginning?
Is this an artifact of the volumes used in the mix or do you think it's more structural, or is it simply related to taste? I think this subject came up before and someone called it "a motif".
