Flex time and minor tempo adjustments

Hey y'all!
So I'm working on a project in which vintage analog synths were run through tape before being digitized and brought into logic. Because tape is tape, this introduced some drift into the tempo. Instead of it being a nice clean 120bpm, it's 120.0103 and I want to use flex time to slow it down by 0.0103.
So when I have the flex algorithm set to polyphonic (or anything other than "off") and I have my flex markers in place, I'm expecting to see that when I change the project tempo to 120bpm, the waveform turns orange, indicating that the audio has been stretched.
The audio is NOT turning orange and when I listen to it, it doesn't sound like any adjustments have been made. Is Logic just disregarding this tempo adjustment as negligible?? Or is it actually stretching the audio but there's just a bug in how it's being displayed?
Thanks in advance for any help y'all can provide!

is it actually stretching the audio but there's just a bug in how it's being displayed?
Logic is indeed stretching the audio. It's just not showing the color change. This is because the tempo change is so slight. You will notice the same thing if you drag the edge of the region to cause a tempo change to only this region. If you zoom in close in order to make a very small change, you'll notice that the color change doesn't happen as soon as you start dragging. The color change only appears after your dragging creates a change of a certain magnitude.
So it's the same phenomenon, whether you're changing the project tempo, or just changing the tempo of one region. The threshold seems to be about 0.5%. Is this a bug, or is it just a design choice? I think probably the latter.

Clicks and pops with flex time and fades

I am getting clicks and pops on tracks using flex time and fades. Any suggestions?
Thanks

Probably the simplest solution to this bug (it appears to not be creating zero crossed edits when creating a fade over flexed audio) is to cut the area to be faded into small region and render (or bounce in place) the small section, then fade it.

Flex Time with variable tempo not working correctly.

Hey,
Has anyone else noticed that Flex Time doesn't work as intended if you have variable tempo?
To clarify, I recorded a band playing their song and then figured out their various natural tempo changes and adjusted the Global Tempo Track accordingly.
Then, the drummer recorded his part to a click on that track, obviously keeping with the natural tempo changes that the band played to.
Quantization of MIDI works just fine, as in, it matches the increases and decreases in tempo.
However, attempting to quantize an audio track using Flex Time does not work properly.
I was just wondering if there is something that I'm doing wrong or if this is a known bug.
Thanks,
William

Thank you for your answers!
But there are several Problems using a dummy field in an IDOC structure. We have got a naming convension so that we can't create an IDOC-like structure named ORDRSP.ORDERS05.
But perhaps I am thinking to complex and there is an easier way to add a dummy field to an IDOC structure.
Could you perhaps also suggest a solution for that dummy field problem?
Many thanks and kind regards,
Steven

Change Flex Time Original Detected Tempo?

When activating flex time on an audio track it looks like Logic goes by whatever tempo is currently active for the project to define what the original tempo is for that region of audio. Is there a way to tell Logic that the region has a different tempo after it has already been scanned with flex time?
I ask this because on occasion I will mix radio shows that use whole songs and I mix them in time to move with tempo changes for various songs. Sometimes I will be off by a small percentage as to what the actual bpm for a song is when activating flex time on a track. Because that is off, it won't match what the project tempo really is. I will then have to rename the original audio file to make Logic think it's a different file and then re-do the process with flex time. I would like to be able to change the source tempo for the region that has already been flex timed so that I won't have to keep re-importing the same audio to rescan it again and again with flex time.

I've been dealing with this today.
I needed to go from 87bpm to 89bpm. Set the tempo to 89bpm and turned flex time on and of course realized that I had to be in 87 for it to lock properly to the grid. I unticked the flextime box and went back to 87 and everything stretched. I then deleted all the markers (as there was not a rescan option) which solved the stretch issue but as there is no option to rescan I can't get any markers up. This upsets me deeply. This is about to give me an ulcer..
There needs to be an option to rescan for transient markers.

Flex Time and Groupings

Is there a way of keeping Flex Timing from editing all the tracks that are within the same grouping other that removing the group from the track being modified? I think it's a great idea for Flex Timing to modify all grouped tracks simultaneously, but when Group Clutch is disabled it should disable the Flex Edit feature in this regard as well. I think this needs an updated fix.

Firstly make one instrument the "groove-master" so to speak. You'll have to decide on this to start with. Once you are done editing this "reference track" you can start synch all other material to it, one at the time. Depending on the complexity of your material, you can use different alignment techniques to accomplish this, such as tempo curving and flexing to name but a few. If you are not sure how to do that, you'll have to hop on the Internet to find useable guidance.
And from a producers point of few I would also consider if it wasn't more efficient and musically rewarding to get a new record session going?

Flex time and fades at the same time?

I can't seem to use fades and flex pitch at the same time on an audio track? Is this a bug or is this the way it should be? Or am I missing something? Or is there a way to work around this?

You need to do the flexing, bounce in place and continue with fade work. Or vice versa. Only heaven knows, when this will be fixed.

Need flex time help, lots of songs, lots of BPM's multiple tempos

Newbie here, trying to finally make the switch from Pro Tolls to Logic and flex time really sold me but I'm having some growing pains that I need to speed up for my current project.
I have about 20 songs that I need to:
first, find the bpm for each (quickly)
second, be able to mark them in a way that the bpm for each song would change to match the tempo track (which will fluctuate through out the editing process)
third, some how still have control of the anchor point in flex time which seems to get locked
In the end I am trying to create a remix of multiple songs that start off with different bpm's and fluctuating tempo.
I am able to do most of this but I think I am missing some steps, or perhaps the order of steps, that would make this process go much faster. I have worked other programs such as Ableton Live and elastic time in Pro Tools and at times it seems I can handle whole songs better in those programs than in Logic but I'm sure it more user error than the actual program.
I welcome any and all suggestions. Thanks.

Received this advice and responded on another forum but still need help.
Thanks for the response!
Had a few problems trying your suggestions.
*"Finding BPM: select the audio region and choose from the local Arrange area menu: Audio > Detect Tempo."*
Since it is a whole song and not just a part, such as drums, with well defined transients, it either can't detect the tempo or when it does it is wrong.
*"Make it follow the tempo track: Use Flex Time (in the track parameters, choose a Flex mode). "*
This would be fine if I didn't have to redefine all the transient markers as correct flex markers. Since Flex Time has problems defining the correct transient markers for complete songs it can be very time consuming.
Maybe I'm still missing something?
*"Third: what anchor? Do you mean the transient? Or the flex markers? You can move the transients in the Sample editor, and the Flex markers right on the track in Flex view (Click the Flex button in your toolbar)."*
The audio region anchor in the sample edit window, the orange arrow. I think this is some how turned off after turning on flex time and I am unable to move it. I use this to line up the first beat if there is something before the music starts, such as someone speaking or a lead in with a different tempo than the song tempo, that I would still like to keep. That way I can move the region in the arrange window and it will line up according to the first beat and not the beginning of the region. Am I making any sense?

Flex time: manual moving of some notes?

I'd like to select 3/4 notes of a guitar solo and move them up (because they are too delayed in relation to the tempo) but I can't find the way to do it. I only get a stretching effect on all previous notes. How can i do?

Is there a way to completely undo all flex time mods to an audio file?

I have an audio drum track that i thoroughly destroyed messing around with flex time and audio quantizing. I believe these are nondestructive edits, but i can't find anyway to get it totally back to its original state. Is this possible?
Thanks

No you can bounce in place and ease processing..
but thats still non-destructive cause logic creates a new file.
I'm sure our friend has a file about somewhere just doesn't know how to get to it
TXBDan are you looking for the audio file name thats the same as your region file?
If so than try remembering what the original file was called and look for that.
if you can't remember the name than try organise the files by date in your audio file folder and checking the files that were created on the day of the recording..

What does "Analyze audio for flex time editing" in Garage Band? It's taking so long(3 days)! and I can't shut down my pc.

Did you ever figure out what was going on? i've got the same issue.
I record 2 hour choir practices then edit the talking out to make more useful accompaniments for personal practice. During my editing process my MacBk Pro (0r GarageBand) decides it needs to "Analyzing audio for Flex Time Editing". It will finish doing it and immediately start over again. I can not cancel it so I just have to force quit Garageband and lose eveeryrthing I have editied since my last Save. I've shut my mac totally off and rebooted and to no avail. Any suggestions?

'Clicks and Pops' using Flex Time?

Has anyone experienced this? Whenever I use Flex time on a vocal, I get clicks and pops, at very random places. It happens more when the vocal is powerful, (although not overclipped),
has anyone experienced something similar, and knows of a fix or a solution?
thank you.

Probably the simplest solution to this bug (it appears to not be creating zero crossed edits when creating a fade over flexed audio) is to cut the area to be faded into small region and render (or bounce in place) the small section, then fade it.

Why can't I cut and edit a track anymore without Flex Time activating by itself?

Everytime I try to cut a track Flex Time activates itself. It's like I am forced to use Flex Time even though I don't want to. If I unticked Flex Time, it keeps activates itself no matter what. This garageBand 11 is just horrible. I wanna go back to the old one

Flex Time Creates Random Pops

Flex time is creating random pops after just minor correction of a monophonic bass line. The pops vary depending on where the playback starts in the file and they are recorded into merged or bounce in place audio. No plugs on the channel either.
Bob

I am getting that exact same problem too. A bass line that after using Flex time on, would randomly get clicks on it. I think it's doing it to the guitar lines too.
What seemed to work for me was changing the Flex time setting from Monophonic to Slicing. It kind of defeats the purpose of Flex time, but at least it sounds right again.
Hope Apple fixes this soon!

Enabling flex time speeds up my track

Hi guys,
I have this problem with some frequency. I enable the purple "Flex time" button for a track, and the track instantly slows down. Here's a screenshot that sort of shows what happens:
As you can see, just clicking that purple button slows the track considerably. I want to start editing with the track at the existing speed.
There are no flex markers in the track
I've tried Edit->Tempo->Remove Tempo Information From Audio File and it had no effect on the behavior

Hi Thi Thach,
You're having the same problem as me. You'll be happy to know that I solved my problem.
(Albeit at the expense of keeping my Mac user profile linked to my Apple ID)
The shutdown delay is due to a file called:
"com.apple.coreservices.appleid.authentication.plist"
It is located in the folder:
"/System/Library/LaunchAgents/"
You have to trash that file (the OS will ask you for the admin password) and then restart the system. After that, all shutdowns will become very fast as there will be no 20-second delay.
This file is responsible for linking your user profile on the Mac with your Apple ID. Apple gives you the option of linking them so that if you forget your login password on the Mac, you can reset it by using your Apple ID.
Once you trash that file and restart the system, if you go to "Users & Groups" under "System Preferences" and look at your user page, you will find that the system forgot your Apple ID that you associated with your user profile. Instead, next to where it says "Apple ID" on your user page, you'll find a button called "Set". If you set it again to your Apple ID, the shutdown delay will come back.
If it's important for you to keep your Mac user profile and your Apple ID linked, then don't trash the file and just live with the shutdown delay.
Of course, this process is fully reversible: You can always return the file where it belongs and restart and you'll be right back where you started.

Loving Flex Time

For the past few days I've been editing vocals for the first using flex time for a remix. the original tempo of the song was around 89-90's. I wasn't provided the original tempo. But my remix is 120 I imported the vocals put the tracks on Polyphonic and they pretty much snap to where they should be at a 120 tempo and moving vocals around for different phrasing is a blast. This remix would have been a breeze if the vocals were delivered separately as lead and stereo backgrounds but was delivered as one stereo file lead and backgrounds together.

I am getting that exact same problem too. A bass line that after using Flex time on, would randomly get clicks on it. I think it's doing it to the guitar lines too.
