Make an Audio File Match the Project Tempo (278)

[space]

Back to basics here, David's book page 278).

 

In the example David uses the tambourine, once this is dragged into the arrange window, you press flex and then Rhythmic. The file is 'automatically time-stretched to match the tempo of your project'.

 

I though I'd try this with the loops in the additional media folder. In David's book project and a completely new one. The Trip-hop loop worked as expected, the region changed shape and got smaller, it fitted the tempo.

 

Then I tried the DrumLoop.aif file, I went to the different flex modes and it didn't match the project tempo at all. The region didn't change shape like the trip-hop region didn't fit the project tempo at all??

 

I get that you time stretch it using the Option key, though what about doing it like the book says?

 

Thanks

I actuall tried this on a Logic 101 course the other day and again at home, and the Tambo was already in the correct tempo and correctly spotted. Is that right? It's absolutely no big deal if that error snuck past you but am i correct?

[David Nahmani]

No, you either grabbed the wrong file, or performed the exercise twice. If you grab the correct file it should be too long until you turn on Flex. The correct file is listed on step 4 p278. It's Logic 9 Files > Media > Additional Media > Tambourine.aif.

 

There is however a bug in Logic 9 where sometimes it recognizes the same name as a pre-existing file in the Bin, then it just uses the file in the Bin rather than the one you're trying to import. But wipe out your drive from all lesson files, reinstall the lesson files, and try the exercise again, it'll work as described in the book.

David,

 

Well i trashed the Logic 9 Files Folder, emptied the Trash, recopied the entire folder from the DVD in the book, opened Sunday Morning, added the track, opened the Browser in Logic, navigated to the Tambourine.aif File in the Additional Media Folder and the exact same thing occurred. The file is in the correct Tempo and runs from Bar 1 to end at the beginning of Bar 101. The Tambourine plays in the correct song Tempo from bar 29 to Bar 37, then from Bar 61 to Bar 69 and from Bar 81 to the end. All 1 continuous Audio File

 

Please understand i'm NOT bitching. I was originally checking whether i'd done something wrong, or if this was a known slip up on the DVD manufacture. And now i'm just confirming it's the case. When i preview the file in the Browser, it plays slower than the song Tempo and it's an 8 Bar Loop. But when i drag it to the Arrange Area, it behaves as i've described above. If i'm doing something wrong, i can't figure out what it is

peeb, that's proof enough that you are not doing anything wrong, but also that I didn't do anything wrong, and that the DVD manufacturer is not at fault either.

 

So my guess is it's a bug in Logic, as I explained earlier. You are importing one file, but Logic places another one on the track (the one of the same name present in the Bin).

 

I don't know why you experience that bug as I, myself, never experienced it - not once - and I have taught that class maybe 15 times since the book was out, so about 150 students doing the same exercise at the same time, all together. As you can imagine, the media files were thoroughly tested by two independent Apple Certified Trainers before the DVDs went to press, and they didn't have that problem either. So my guess is we're using a different version of Logic, and you're probably using a more recent one that displays the bug. Keep in mind the book is written for and tested in 9.0.

 

However, as I explained, the bug is due to the presence of the completed Tambourine.aif file in the Bin of this project. So you should try the following:

 

1) Install the book files on your desktop.

2) Delete the following file from the book files: Logic 9 Files/Media/Sunday Morning/Audio Files/Tambourine.aif

3) Try the exercise now.

 

My guess is that should force Logic to import the file you're asking it to import rather than use the one present in the Bin since it's no longer in the Bin.

 

I'm just guessing, as, again, I've never seen that problem myself. But going by your description, that's as close as I can get to a workable solution.

[peeb]

Yep, that made it work as per the Lesson David. As it happens, i sat my 101 Exam this morning and spoke to the instructor about it because he has had the situation i described occur the last couple of times he has taught the Course. He obviously could have gotten to the bottom of it, but in the middle of teaching you just kind of have to move on

 

Anyway, weird bug but understood now

 

Thanks for the feedback. Amazing to so easily be able to talk to the author of the very text book i'm studying. Very grateful

Thanks David for getting back and clearing that one up for both of us!

 

There is another thing I've noticed with doing this, just for the purpose of this I recorded audio in one project and then importing it to another, via the browser and then flex timing it.

 

Say I've recorded a 2 bar guitar loop, with one note/chord on each beat at 120 bpm. I've then set up another project and set the bpm to say 100, then I navigate to the previous project in the browser and locate the 2 bar guitar loop and drag it to the 100 bpm project.

 

But once I've imported it to the new project (100bpm) what I find is there is a lot more region before the the first beat/strum and more region after the last beat/strum if you see what I mean? I get that if you recorded some audio, there is more region there if you pull from the bottom corners on each side of it. Also when you record its obvious to see that the regions starts a few beats before the cycle area, but once you press stop it looks like an exact four bar region, and the bit you see before the cycle area is not there.

 

What I'm finding is that once I import a region into another project I'm getting the extra on either side, is there a way round this? What I did was to marquee the recorded audio, crop it and then flex time it to match up, though is there a way to not crop it at all?

 

In the pic, the first region would be the original and the second region is what the original/imported region would look like, once its been imported into the 100bpm project (for this pic I just copied it, put it on the track below and extended it, for show).

 

Many thanks again

re p 278

I've had the same problem. If we're in the middle of the Lesson I tell students to delete from the bin (same effect):

 

"Undo your way back to before you imported the Tambourine file.

Click the Media Icon. Open the Bin tab. Select Tambourine.aif. Go to (bin local) Audio File > Delete File(s).

Now try importing the Tambourine file from “Additional Media”. Should work."

So how would we go about finding tempo when taking tracks off of itunes to match samples from cd to match logic? Your book has helped tremendously btw, I recently finished my MIDI class at La recording school with an A thx to that book.

Try the BPM counter

Hi

 

Did you read/do the entire Lesson 7?

 

See the very 1st exercise (p254): "Matching the Project Tempo to an Audio Region's Tempo"

 

Then (very carefully) do p262 steps 1-8 to understand how you could use Flex to change the tempo of the audio (if you need to).
