jpeek345 Posted March 29, 2020 Share Posted March 29, 2020 Hi, I am writing to ask why my Logic stock tuner gives me an "A-A#"(lands on 'A') when I am testing an Eminor MIDI chord consisting of 3 'E' notes, a 'G' and a 'B'? I tested an 'E' on a seperate tuner app and it is definitely not an 'A'. Thank you. Sincerely, jpeek345 Quote Link to comment Share on other sites More sharing options...
David Nahmani Posted March 29, 2020 Share Posted March 29, 2020 What instrument is your MIDI chord triggering? Do you want to attach an example project here that showcases this issue? How to attach files to your post Quote Link to comment Share on other sites More sharing options...
Eriksimon Posted March 30, 2020 Share Posted March 30, 2020 The tuner is not meant to be used with chords, but with single notes. It may be that some harmonic within this chord is in fact picked up by the tuner, like the difference between any two of those three notes might turn out to be an A - I'm too lazy to calculate that now.

des99 Posted March 30, 2020 Share Posted March 30, 2020 Indeed, if you're playing chords into a tuner, then you're doing it wrong. That is not how audio tuners work - they are for single notes. Anything else and the display is meaningless. Quote Link to comment Share on other sites More sharing options...
jpeek345 Posted August 1, 2021 Author Share Posted August 1, 2021 So are you two saying that depending on what waveforms the chord demos predominately...thats what the tuner will pick up even if the chord was comprised of 3 'E' notes across a three octave chord?

What they're saying is that most tuners, like Logic's stock tuner, are meant to detect the pitch of a single note at a time. If you have multiple notes at different pitches (such as a chord), the tuner may or may not detect a pitch, but will often get confused and oscillate between different readings. If the multiple notes are all the same notes at different octaves, then the tuner should detect the pitch. There are polyphonic tuners (hardware and plug-in) that can detect multiple notes at a time, such as the TC Electronic Polytune: https://www.tcelectronic.com/product.html?modelCode=P0CKF Quote Link to comment Share on other sites More sharing options...

No, what I'm saying is, if you're putting an audio signal or anything other than what's it's intended to work with - a single note of a clearly defined pitch, the display or output is meaningless as what the tuner tries to lock on to is indeterminate. If I've designed a tool to understand one voice in English, and I get ten people to shout at the tool all at once, then the tool can't do the job it's designed for, as the input is outside of the intended use case and parameters. A tuner is designed to extract the pitch from a single note accurately, so you can tune it accurately. Anything else won't work. And yes, there *are* Poly tuners - I use TC's Polytune, both plugin and hardware, and it's great. But again, it's not really designed to give you chord readouts, it's designed for you to strum all six strings of a guitar, and get a rough per-string readout of pitch so you can see at a glance which strings are slightly out and tune them.

That's an excellent example. Try having multiple people speaking together into a voice recognition app and you can't possibly expect the readout to be accurate.
