As far as what the OP wants to do, I'm confused. Any tuner that passes through the signal will do what is being requested. I think there must be some other factor that I'm not following. It sounds like what is being asked for is a tuner that outputs a "pitch corrected" note, but that's not how tuners work.

He's looking for something that will pass the data (not a readout of the note) to another program or app so that the other program can use it in some way for something else.
