Hi Chris, (or anybody else) just listening to John O’Callaghans new tune, currently unnamed. Do you have any idea what he’s doing with the bassline, at first listen it sounds like a normal key change down the range, but it almost seems to pitch bend down, there’s something different about it. Any clue?
