xjulia Posted November 21, 2021 Share Posted November 21, 2021 I have a track recorded from a cassette tape and the speed is not correct. I have to slow down half a tone. How can I do it? I have tried it with Pitch correction but it comes out distorted ... Thanks! Quote Link to comment Share on other sites More sharing options...
triplets Posted November 21, 2021 Share Posted November 21, 2021 I imagine there's drums and instruments on the track, which makes it harder to be clean, especially on cymbals. Use Varispeed to bring the whole project down with speed and pitch. Once you got the pitch set, bounce the project. Then bring the file back in and you can speed it back up to the original tempo. But none of this will be a flawless transposition. There will always be artifacts, even barely audible. Quote Link to comment Share on other sites More sharing options...
xjulia Posted November 21, 2021 Author Share Posted November 21, 2021 (edited) When I change Varispeed I can't hear the track... What I'm doing wrong? Edited November 21, 2021 by xjulia Quote Link to comment Share on other sites More sharing options...
xjulia Posted November 21, 2021 Author Share Posted November 21, 2021 I did with the Flex time / Speed FX option and it goes well. is correct? Is not the exactly way... how can I reduce the speed half a tone exactly? Quote Link to comment Share on other sites More sharing options...
triplets Posted November 21, 2021 Share Posted November 21, 2021 No exact way to do it. You gotta use your ear. Quote Link to comment Share on other sites More sharing options...
Atlas007 Posted November 21, 2021 Share Posted November 21, 2021 Have you considered Melodyne to achieve that? Quote Link to comment Share on other sites More sharing options...
fuzzfilth Posted November 21, 2021 Share Posted November 21, 2021 There is no reason to assume that the cassette recorder was *exactly* a half step off, so there is no point in correcting by *exactly* a half step. - Switch the audio tracks with the tape transfer to Flex Speed, as this will affect tempo and pitch, just like tape does - create another track with an unchorused rhodes piano - while you keep playing on the rhodes in the supposed key of the song, change the project tempo until the audio tracks sound perfectly in tune with the e-piano - Bounce-In-Place the tape tracks to make their speed permanent This should not take more than a minute.

xjulia Posted November 22, 2021 Author Share Posted November 22, 2021 ok, I understand the piano solution. thanks! But I think there should be a way to change the speed by notes... it would be simpler, and more if I have to do it with all the cassettes... bufff...

Not in Logic. But there's an app called Transcribe where you can detune a song by half-steps and cents and then export the file. I use it constantly for transcribing music, especially when the original recording is not on pitch. https://www.seventhstring.com/xscribe/overview.html Quote Link to comment Share on other sites More sharing options...

xjulia Posted December 4, 2021 Author Share Posted December 4, 2021 Thanks triplets for your offer I think the problem was with the Record enable and Input monitoring buttons. Both must be disabled. Now it works... Quote Link to comment Share on other sites More sharing options...
