Quantize Strength - Audio Regions

Is it possible to change the quantize strength when quantizing an audio region?
I've split up a 4-bar guitar riff using Strip Silence in the arrange window. Then I opened up the event edit list to quantize the region to 16th notes but couldn't figure out how to change the quantize strength. Any suggestions?

The quantise Strength settings are in the region parameter boz in the inspector. To see them go to +View > Extended Region Parameters+ on the Arrange page menu.
Rodger.
This is correct, however, these extended options are not available in the 'destructive' Q functions of the Event and Matrix (Piano Roll editors), which are needed to quantise audio regions within the Arrange editor.

Is there a way of moving/quantizing multiple audio regions at once to the nearest bar/beat/division?

Hi,
I'm having trouble finding a solution which I hope turns out to be fairly simple. Here's my problem:
I often make drum beats from audio files that looks something like this:
What I'd like to know is if there is a way to highlight say all of the snare audio regions and snap or quantize the "audio region start" to the nearest beat or division. I've been looking everywhere and I just can't seem to find a way to do it to multiple regions at once. It seems like somehting that should maybe be fairly simple. Turning "Flex" on doesn't work as that quantizes the transients as opposed to just the start of each audio region.
The reason I ask is that sometimes when zooming in fully, it turns out some of the regions are not exactly on the grid line.
I hope I made sense there and I'd appreciate any help. Many thanks in advance.

Hi
The "traditional" way to quantise audio regions is to use the quantise functionality in the Event List.

Cant seem to quantize audio regions?

I have read the manual which says the following:
"In order to use quantization on an audio region, you need to assign a flex mode to the parent audio track, and select the Flex parameter in the Region Parameter box for that region....
To change the quantization grid division for selected audio and/or MIDI regions
Choose a value from the Quantize pop-up menu in the Inspector’s Region Parameter box."
I've done that but nothing happens??
Also I don't understand the correlation between the track parameter box, and the region parameter box, do I have to set them both to the quantize setting that I want, or just one of them?? I have tried it all ways and I cant get it to work.

Worth downloading MPC quantizes if you can - they were made for drums. (Wish Logic would come up with some new quantizes though - they've been the same since year dot)...
You can download the MPC quantizes here:
http://www.logic-cafe.com/Article_View.asp?ID=14&CategoryID=8
You'll need to open the above Logic song & copy the folders to your song (preferably your own template so that they're there every). Open the MPC folders in the song, select all regions simultaneously, then select "Make Groove template" from the Quantize menu in the Inspector. Hide the folders (don't delete them - they need to be there in order for Logic to remember the Quantizes).
You can also make extensive use of the "Delay" offset in the inspector (moving regions forward or back in time in small increments) or better still use the "Nudge Left" / "Nudge Right" functions (set to ticks ors samples). I have these two buttons (as well as "Nudge Value") permanently in my arrange toolbar.

Flex mode on audio region and audio to midi quantize makes Logic crash..

Need confirmation on this also.. Choose an audio track and select Flex mode. Double click on the audio region so you get the sample editor. Choose Factory > Audio to MIDI Groove Template.. Select Try and then Use.. Logic freezes and goes down.

Yes it does it all the time here ...and creates (crashed) (crashed) (crashed) versions of the project.
If you open the original project it opens OK ...when you try to open any of these (crashed) ones it crashes again..
It's the same with audio to score...when you press Use
They have removed the Groove template function from the Menu as well....although you can do it via Quantize in the inspector ...would be nice to be in the menu though....

Quantizing of Audio causing region corruption?

I have noticed that when I quantize, then de-quantize audio regions numerous times (trying to learn what works best in a given instance), the note placement eventually becomes way off, even with no quantize is selected. Why is this and what can be done to prevent it? Is there a way to restore an audio region back to the original file's condition?
This problem makes me not want to experiment until I know there is a way to get back to 'square one'!
Thanks!

I need to do that {turn flex off} per track, no?
Not exactly. Flex can be controlled (i.e., turned on and off) on a per track basis, and also on a per region basis (except that it must be on at the track level if you want it to be on at the region level). So you can turn Flex off per track, but you're not required to turn Flex off per track, if all you really want to accomplish is turn Flex off for one region.
The Track Inspector has a menu for selecting Flex modes, and one choice on that menu is "Off." And this is the exact same menu that appears in the track header when you press ⌘F. That keystroke is the equivalent of this command in the Arrange window local menu: View > Flex View. It's also the equivalent of the Flex button in the toolbar. It's important to understand that showing and hiding Flex information is a separate matter from turning Flex on and off.
The Region Inspector has a checkbox called Flex. This checkbox only appears if Flex is turned on for the track hosting this region. The point of this checkbox is that you can turn Flex on for a track, and then make one or more regions on that track exempt from Flex.
The Flex button at the top of Arrange only turns on the flex View, correct?
Exactly. This has to do with what I said about the difference between enabling Flex and making Flex visible. Two different things.
Is it possible that although the original file is not changed, the Region being quantized could get messed up to the point of becoming unusable?
I don't think so.
I think there is a chance that I am getting this problem and the varispeed/autopunch problems mixed up/mixed together
That could be. These features tend to overlap each other somewhat, so it's easy to get confused, especially if you're trying to use a bunch of new, powerful features all at the same time. But there's nothing wrong with that, as long as you're willing to tolerate the confusion. Then you can take a step back and examine each feature separately, to figure out what's causing what.
There might be less confusion if you learn one feature first, before you jump into another one. Some people might prefer that approach. But it's perfectly fine to take some chances and jump right into the deep end, as long as you realize that every now and then you'll be a little bit over your head. No harm done! It's just different approaches to learning, and you should take whatever approach suits you.
sometimes one problem is confused for another because we're just not sharp enough to make the distinction
This is what happens when you try to learn multiple advanced features at once, but there's nothing wrong with doing it that way, if you like to do it that way.
Sorry for all the questions
Don't be sorry, that's what this place is for. And you're asking good questions that are also probably on the minds of lots of other present and future readers.

Setting the project tempo to match an audio region

The manual is pretty clear on how to do this but it talks in terms of one bar audio regions vs. an entire song. I'm trying to do a remix of a song that has subtle although very definate tempo variances throughout. The audio file of the original is imported into Logic and I've tried Options>Tempo>Adjust Tempo using Region Length and Locators but it's giving me one global tempo which does not match up when I compare the audio file to the click. It's not telling me where the tempo changes occur in my tempo track either. I'm wondering if it's even possible to do this. I could beatmap it? I don't know. Should be an easy thing to do.
I suppose a workaround could be to bus the audio file to an aux and then record that aux's output like I was recording it live but that seems like overkill.

The best tool for this is the beatmapping track. It's pretty easy to do, depending on your material, and it will conform Logic's clock to your audio's tempo, with appropriate tempo changes.
Once you beatmapped your track, Logic is in sync with it and you can then add sequences and use quantize etc.
If you are not sure how beat mapping works, shout back...

Help getting desired audio region into the sample editor

Chapter 21 of the manual is of no help. Assume I have to audio regions on the same track--singer sang first part of song..... big pause... then sings second half of song ( same track but two distinct ausio regions) All I want to do is be able to quickly have a desire region show up in the sample editor to do edits. The actual instructions about editing are pretty clear. But getting the correct region to show up in the sample editor is the hard part. Even if I click the audio track and click the audio region desired, some other region or some region on another track will be there. And I can't change. This shouldn't be that hard. +I do not to have this problem with piano roll and software intrument regions. You simply click a software track region and click piano roll and the detail of the region shows up+...... Is there a simple protocol for getting a desired audio region to show up in sample editor. Notice that there is no clear explanation for this basic, antecedent task in Chapter 21.

You can't really 'quantize' audio. If it is a single track like stacatto mute guitar, or snare drum hits - you could. Use the 'strip silence command' and then in the list editor highlight all the individual pieces of audio and quantize that.
But if the audio is continous or there are too many notes very close together you will not be able to do that.
If you mean that the track was a 'real guitar' (by musiclab) - yes you can quantize the midi notes.

Move the audio regions?

when i move the audio regions in arrange window(zoom in maximum),i found there is always a 1/960 beat quantize,no matter i hold down Control or not.could anybody tell me how can i move the audio region any where i want without that 1/960 beat quantize?
thx!

Actually, this is Logic's PPQ res. To be more exacting with the audio regions you'll have to open the sample editor and move the anchor. Very time consuming-hope this gets addressed.

HELP: Audio regions get out of sync when I change tempo

I've got Logic Pro 9. I've recorded audio on a few tracks, and they sound great together. When I go to change tempo (either in the transport bar or in the tempo track), the regions change in size and move around horizontally, and get out of sync as a result.
Has anyone had this problem? Why should changing the tempo of the project affect the position of the audio regions IN RELATION TO ONE ANOTHER? I want them to stay in sync after changing tempo.
Thanks in advance!

The reason they move is that logic is a bar/beat based Sequencer rather than a time based sequencer like pro tools. The regions adhere to the tempo grid and when the tempo is changed, they seemingly lengthen or shorten because the tempo shifts the bar/beat grid with respect to time--and audio regions normally Are inflexible and last for a fixed amount of time no matter what the tempo is changed to. This is an advantage when your audio is quantized musical events, but for non musical events it's a disaster because it screws up your edits.
To fix the problem, find the timelock key command and highlight all regions you don't want the tempo change to affect. after selecting them all, timelock them with this command.
But, from your post Im guessing that you have bigger problems than this....Timelocking regions will only prevent region starts from shifting around and will leave all your edits unchanged. but it won't speed or slow down your audio; It will not alter lengths to fit a new tempo. if your tracks are music tracks in a certain tempo and you are trying to change the tempo of your recorded audio, you must enable the flex mode on each track. For this you should read the part of the manual on the flex engine. Bear in mind that the audio quality of this ranges from ok to terrible depending on the material.
The moral of the story is that you should try to arrive at the correct tempo before recording audio tracks.

Quantize Strength - Piano Roll Window

How do you change the quantize strength in the piano roll window for Logic 8? In Logic 7, I would use my short cut to open the Extended Region Parameters window. In Logic 8, this seems only possible in the arrange window. Couldn't find this info anywhere in the manual or online.
Thanks in advance.

Hi Armen,
I haven't used 7, but I found what you described in 8. On the upeer left are all sorts of quantise parameters.

Unable to edit an Audio Region (just want to change gain)

Hello,
In a particular audio region I am unable to change gain in that the "Change Gain" command (as well as all the other functions) are Grayed-out FOR THIS REGION. I am in Sample Editor>Functions>Change Gain.
There are over 200 audio regions in this file. Most of them have NONE of the edit functions grayed-out.
A few other regions have all the edit functions Grayed-out except for Change gain.
Almost all of the audio regions are from apple loops. I have not edited any of the regions except for some regions ending points, and volume automation added.
Why would this one particular audio region ("Country Night") by un-editable?
(NONE of the tracks are locked.)
please help

Is it a file in .caf format? If so, note that compressed Audio formats can't be edited destructively. Convert to aiff/wav before.
Btw, there is a Gain function in the Region Inspector since Logic 9, so there is no need to change the gain in the sample editor anymore.

Midi notes or audio region do not play at the start of a bar?

I am having an issue with a midi loop I have created. If I let the song play a bit until it reaches the loop, logic works just as you'd expect it and everything plays correctly. But if I stop the song, or if I set the song into cycle mode so it repeats, the very first note of the midi loop is ignored, and not played.
So for example, if I set the cursor to start at bar 9, the starting point of the loop, the first midi note is not played. But if a set the cursor at bar 8 and let it play into bar 9 and the loop, all of the notes in the loop play correctly.
I found the following description of the same problem on another forum, but it seemed to suggest that there is no fix for this, which if true, seems kinda bad for a pro application. I was wondering if anyone knew of a workaround or fix to this, because its really annoying missing the notes, or having to expand the cycle region just to get all of the notes to play. Here is the text from the other forum:
_Logic doesn't play the very start of my audio regions when I start playback_
Question: If a region starts at e.g. 1 1 1 1, and it starts playing from the same position, it seems that Logic misses the first few samples - which is especially noticeable with fast-attack transients.
Answer: Apparently Logic doesn't use some kind of pre-play buffering. The workaround is to have your entire song start e.g. one bar later, at 2 1 1 1, and let Logic play from 1 1 1 1. This workaround obviously doesn't work if you've set up a cycle - in which case Logic will miss the first samples when it starts playing as well. Next time it loops through the cycle it does play properly. There's no workaround for this - it's a serious shortcoming of the way Logic handles audio playback. With cycles, you could resort to using the Pause instead of the Play button/command: this will let you start playback from somewhere before the start of the cycle instead of starting at cycle-start (which is what Play does).

I'm having the same problem.
one workaround is to change the delay to +1/192=20 in the delay box in inspector on the given midi track...but this is a terrible thing to have to do over and over again.
PLEASE help if you know what's going on.....I ran logic on my macbook and this NEVER happened. I just bought a macbook pro 2.5 and it's apparently now an issue?
I have searched the net for fixes, and none work....logic does have a pre-play buffer, but it's range isnt large enough to buffer the instrument I'm using...which means the range is less than 1/192...come on....that's messed.
If anyone figures this out, please message me back at [email protected]

Beat Mapping is changing speed of audio region, not the metronome!!!

Hi Everyone,
I just today learned about beat mapping in Logic. I used it on one song that i'd recorded previously without a click track and it worked like a charm. I'm trying to use it on a different song now (same situation: previously recorded with no click) but for some reason with this song, it's changing the speed/length of my audio region to match the metronome instead of changing the speed of the metronome to match the speed of the audio. What's going on?!
Thanks a bunch.

Well after many hours of searching through Logic Forums and flipping through the Logic Reference Manual, all to no avail, I've finally figured out what the problem was. I needed to uncheck the "Follow Te(mpo)" option in the Region Parameter Box for the region I was trying to beat map. The beat mapping process wasn't actually changing the length/speed of my audio region like I said it was in my initial post; it was simply playing over it slower or faster in order to preserve the audio-to-tempo ratio as I made the tempo slower or faster. All I needed to do was uncheck that little box and now beat mapping works exactly as described in the Reference Manual. WHY ON EARTH is the "Follow Te(mpo)" box not mentioned when discussing beat mapping?! More importantly, why is it not mentioned ANYWHERE in the entire Reference Manual?!?!? NOT ONCE!!! unbelievably frustrating.

Overlap audio regions on 1 track without cutting the previous one off

Im trying to overlap multiple audio regions on one track, so that the next one starts before the previous one ends but when i do this, each consecutive overlap basically replaces the remaining region of the one before it. to be more specific in order to maybe paint a better picture of what i am asking... i am creating machine gun audio for a video clip and i have a loop of a single shot plus the shell falling to the ground. im trying to overlap the loops so that the single shot of each come together in rapid fire succession to create the machine gun firing sound, but i want the sound of the shell falling for each shot to continue to play under the multiple copies of the overlapping loop. the problem is, when i overlap multiple loops, its not finishing the noise of the shell falling to the ground for each shot, it only plays the falling shell at the very end when there is no other overlap. i hope i did an ok job explaining what i am asking, haha trying to type this out was much more difficult that initially anticipated. thanks in advance for any help.

That's normal. Audio tracks are not polyphonic. Use several tracks or EXS24.

When recording audio, the soundwaves dont show in the audio region.

I think i must of changed settings accidentally or somewhat, because prior to this, there was no problem. However, now when i record i cant see soundwaves (im not sure what they're called) in the audio region. please help, its really giving me problems cos i really wna record audio.

Try the waveform zoom slider in the lower right hand of the arrange.
If that's not it then check your recording delay in preferences>audio, supposedly if it is set too high what you describe happens.
