Thoughts?

Also, since S1 can do this, why does it still rely on Melodyne for its pitch edit workflow, especially since the bundled Elements version can't even do polyphonic audio, whereas this internal feature apparently can?

Editing fine pitch is far from the same thing as detecting coarse notes / chords.

Is it, though? Coarse pitch is fine pitch snapped to 12-tone frequency scale. And I think being able to detect a multiple pitches from audio clip with a chord is much more sophisticated tech than detecting "fine" pitch of a monophonic audio.

Editing does not equal detecting. One is needed for the other, but not vice versa.

Detecting full chords is not as difficult as you might think. Just look at the spectrogram. There are frequencies about one octave around middle C that stick out as a sore thumb. Those are the notes that make up the chord.

Editing pitch however is a very different thing. Easy to do on monophonic material, just shift it up or down by the amount you detect it's off.

If you (try to) correct pitch on polyphonic material, I imagine the whole thing's pitch goes either up or down.

Is there any tool in the box that can do true polyphonic pitch correction? Say you have a recording of a choir singing a major chord, and let it change it to minor?

Err? That is exactly what my video shows Studio One doing - I'm starting with C, which is then transposed via Chard Track to Em and Am...

Once again, this time straight to the point:

Of what you sparsely wrote, I understood all it did was detecting chords.

Sorry, I usually don't watch videos. Waste of time, need to find earbuds, etc etc.

I thought |chord track working with polyphonic" audio was precise enough, as chord tracks are used to dictate the chords, not just detect them. But perhaps I assumed wrong, indeed

2nd video is much shorter

S1 is a very no frills DAW. The developers don’t waste time adding features where a third party tool can do it better for the most part. In this case Melodyne does polyphonic audio correction which is still rare in any DAW, most still only do monophonic pitch correction.

As for the technology they are different tools. Studios One uses Kort by Zplane) for chord detection, melodyne uses their own algorithms. The two don’t really talk to each other. S1 doesn’t have its own pitch correction solution built in and relies on Melodyne. It could be as simple as Presonus thinking they don’t need to add this feature since Melodyne has probably the best sounding pitch correction algorithm in the market. That’s why they worked with Celemony to create ARA.

Also to answer the thread titles question according to Zplane only two softwares are currently using Kort and S1 is one of them. So I’d say it’s pretty unique unless you use Melodyne editor.

That's very likely, but it's simply jarring to see Melodyne squished in S1's lower panel like that, not to mention the contrasting colour scheme and completely alien workflow...

I felt Reason's or Cubase's pitch editing are much better integrated into the core DAW, but neither does plyphonic audio that's why I was excited that perhaps S1 could in near future, given the tech already on board

Both S1 and Melodyne can extract chords from polyphonic audio to a chord track and via ARA2 they can communicate chord and note information bi-directionally. It's definitely a winning combination, because for a given audio clip, you can decide which program does a better job of chord detection, because each use their own detection algorithms.

Of course Melodyne Editor/Studio can go much further than just chord detection.

That's not to say the combination of Cubase and Melodyne is "chopped liver" -

I'm still waiting for Cubase to incorporate polyphonic audio / chord capabilities into Variaudio before I register my copy of Cubase Pro. Hopefully version 12. If not, I may have to submit to Studio One.

I wonder why more DAWs don't license Kort(and reTune) by Zplane. Or have chord tracks for that matter.

Chord Track working with polyphonic audio - is this unique to Studio One?
