Well, I'm about to step in it now. If I understand, your 'frequency
shifter' is a device that adds (or subtracts) a constant onto the
frequency. I.E A440 now becomes A442 and A880 becomes A882. Is that
right? If that is INDEED the case and you don't find that musically
appalling to listen to, then I don't EVER want to hear whatever you
may think is good because it couldn't POSSIBLY be any good. Call me
whatever names you must but you're just plain WRONG. I don't dispute
that plain speech would likely be just fine but the music would suck.
