    Re: Pitch correction
    The button you're referring to turns the Flex feature on or off -- Flex is the feature that allows GB to do time-shifting and/or pitch-shifting, so it has to be on for those functions, which include pitch correction.

    OK. But on your first screenshot, there is also time quantize. On the second screenshot, you don't have time quantize anymore. Why? And why I don't have time quantize at all there, not matter, dragged I the top edge or not.

    Re: Pitch correction
    I tried transpose slider. It changes all the notes of region, but I need to correct single notes if I sing them uncorrectly (not fitting into the notes). For example, some notes I sing are OK on the same level are my voice and instrument, but some are not fitting to the pitch - there is no help with transpose slider.. ? I made a previous post with another question, please answer to that, too! Thanks!

    Re: Pitch correction
    Here the Time Quantize option is available as long as the Editor pane is tall enough -- if you don't see it try making the Editor pane even taller. Transpose simply moves all the pitches in a selected Region up or down in semitones. If you wanted to pitch-quantize notes you'd use Pitch Correction, which is meant to auto-correct the pitches of notes in a selected Region. But if you wanted to manually change or correct the pitches of individual notes in an Audio Region [like you can in Instrument Regions], GB does not include that feature [Flex Pitch in Logic does that]. GB's pitch correction may or may not get the job done in every case -- it works here to some degree, but not all that well, and certainly not as well as the dedicated Flex Pitch feature in Logic. I guess that's just one of the limitations of working in a free DAW..

    Re: Pitch correction
    I read that correct pitch correction is when right key has chosed. And right key I can find by the last note, isn't? The last note of the sentence is A, so I chosed a minor and to me seems, like I hear the difference. First one is non pitch correction, it sounds a bit rough. And the second track is a pitch correction, do you feel the difference? I'm not a specialist in pitch correction, but it seems like there is a difference, especially first note is different.. The second track is not so rough. What do you think? https://youtu.be/5-cIDrutBQ8

    Re: Pitch correction
    In the example the pitch correction seems to be working -- you can hear it quantizing the pitches in a few places. For smoother pitch correction you might want to turn the Pitch Correction slider down to around 70 -- the default value -- to avoid that warbling of pitch that can be heard on a few notes. The key of a song is not necessarily the last note, though it could be. It's the home pitch & scale that the song is based on -- to recognize this reliably you have to learn music theory (harmony & scales), and train your musical ear. This is usually a gradual learning process..

    Re: Pitch correction
    You wrote it quantizing the pitches in a few places. And you wrote the pitch correction works. So, if it works but only in few places, does it mean that in other places I fit to the melody.. ? But I read from the 5th grade music book, that the last note determines the key. But you say now, it's not always. How is that? Do I also need to select enable flex ( besides limit to key) in case I want pitch correction? If I start to sing, can I at once choose pitch correction with its slider value, limit to key and enable flex? I mean, can I sing at once a pitch corrected vocal?

    Re: Pitch correction
    Yes, pitch correction should only correct pitches that are out of tune -- if some notes are in tune then pitch correction should leave them alone. You don't have to enable Flex for pitch correction, but if you need to time-shift the audio then Flex should be enabled. GB's pitch correction will not correct your singing in realtime as you sing -- it'll work on playback. Regarding music theory, I recommend you check out some of MPV's music theory courses.. https://www.macprovideo.com/library/topic/musictheory?afid=E470KLQ7r9 https://www.macprovideo.com/course/music-theory-109-music-theory-for-daw-musicians?afid=E470KLQ7r9 https://www.macprovideo.com/course/musictheory102-harmony?afid=E470KLQ7r9 https://www.macprovideo.com/course/musictheory101-melody?afid=E470KLQ7r9

    What is time-shift the audio? Is it useful for the vocal, too? Why I need to time-shift the audio?

    You don't need to time-shift the audio. But if you wanted already-recorded audio tracks to play at a different Tempo (like MIDI/Instrument tracks automatically do if you change the Tempo) then enabling it (turning on Flex) will make that possible. If you have no need to change the playback Tempo of a song, then there's no need for time-shifting. Of course, that would be a different topic for a different thread..
