Editing loops in sample editor

I want to take pops and clicks out of a drum loop I edited. I'm using one drum loop. I've varied it at certain points. I shortened a section and then repeated it so it sounds like a role. But when I continued with the transition into the non-edited loop there was a click or pop. I wanted to edit the pop out but when I went to the sample editor it didn't show the transition. It played the loop as though it hadn't been shortened and repeated. My question is how do you view the modified drum loop in the sample edit window and it's transition into the non-modified loop? I want to be able to see the transitions.
Any help would be appreciated, thanks.

Hi feflower
double click on the audio you wish to edit in the arrange window after you have imported it into logic. That will then open the sample editor.
The sample editor is the place you can change the start / end points of the audio file.... cut/paste/fade in/change pitch/speed etc - but all these changes tend to happen destructively - so do keep a backup of the original.
You can just zoom in to the file in the arrange window and perhaps achieve a rough edit from there and then go to the sample edditor to tidy it up a bit.

Not able to increase gain of blue Apple Loop in Sample Editor, even when I bounce in place

As far as I understand things, bouncing in place creates a new audio file that you can alter at will. I have a blue Apple Loop from Logic's library that I want to permanently change the gain on. I can bounce in place but all the functions in the sample editor are greyed out, thus not allowing me to change the gain. The loop is a surround sound loop, I don't know if that matters. It's happened to me in stereo so I don't think so.

Finaly i was able to solve the problem.The other machine was having some firewall blocking the receiver.

Is it poss to edit 2 tracks - mic&pickup, simultaneously in sample editor?

(I'm a total novice in Logic so it's easy to blind me with jargon) I've recorded a guitar with mic and pickup and want to be able to see and edit both tracks at the same time in Sample Editor. Any idea how? The manual says:
"If you’re dealing with an interleaved, or half of a “split stereo” file or Audio Region, both
channels/audio files will be displayed in the Sample Edit window, with the left side on
top, and the right side below."
Is there a way of interleaving my 2 tracks so I can do it this way? Or some other way? Many thanks in advance x

set your 2 tracks up the way you want in the stereo field - hard left and right if you want to be able to de-interleave them later....
Make sure everything else is muted.
Bounce the tracks using the bounce feature under the main out fader on logics mixer.
Your bounced track will be an interleaved stereo file which you can edit in the sample editor (as long as you choose interleaved stereo in the bounce dialogue box).

Sample accurate edits in sample editor

I am new to Logic Pro, having previously worked with Cubase. I understand that the underlying engine of logic is constructed upon beats, frames, ticks etc., but is it possible to do sample accurate editing in the sample editor?
At present any small selection of say 2 or 3 samples in length is often enlarged to many samples. Is this because of the 'snap to' parameter? Is this behaviour unavoidable?
Cheers,
Georgie

Your method is essentially a hack is it not?
For using the sample editor, no
For the arrange, absolutely - but it does work if you can work in such a short time.
It intrigues me that this should be necessary - it reinforces my understanding that Logic is at its core a sequencer, as opposed to a sound editing tool.
Yes, it's roots are in sequencing - still, I am surprised it is still restricted this way.

Can I move audio in logic by the sample in the sample editor to compensate

I wanted a final say on wether or not I can move audio with sample accurate percision by moving the anchor in the sample editor with update in arrange page turned off. i just need a verification of this.
Thanks guys

yes you can and should use the sample editor to make
such compensations. you do this by aligning the
anchor point to the sample or part of the wave form
that you want to correspond to a beat or subdivision
(ideally) though of course it can be any point you
want it to.
if you use 'pickup clock; move object or event to
SPL' KC the anchor point will jump to the SPL.
Philip K is right though; if your entire track is out
by the same amount that you can measure you could use
the sample delay (though of course that will only
delay it not move it forward in time). but you won't
see the waveforms align themselves to the beat
meaning you would have to be aware that that track
has been compensated for.
on balance i would edit with the sample editor.
I was thinking that you could delay the rest
of your tracks by however many samples thus
aligning by compensating everything else though
in real world situations I don't know how practical
this would be. I keep forgetting that you can measure
how many samples you select in the sample editor even
if you cannot see them individually. So I will defer
to the voice of experience on this. If Rohan would use
the Sample editor, then I would tend to agree

Sample Editor - "sample accuracy" is a matter of opinion...

In trying to figure out exactly what was going on with start/anchor/end points in the Sample Editor, I discovered the basic relationship between the Sample Editor and Arrange window... thought this might be useful to others.
Basically, it's a matter of opinion whether or not the Sample Editor truly lets you make sample-accurate edits. By itself, the Sample Editor does let you move the start/anchor/end points to any sample value, and Logic will save and remember these settings, accurate to the sample.
But, you can't rely on those sample-accurate edits when you place the region in the Arrange window. Logic always "remembers" them, but the results in the Arrange window can get sloppy.
Bottom line: Logic forces all region start and end boundaries to rounded tick values. So, if you go into the Sample Editor and adjust the start/anchor/end by samples, it's impossible for all of these edits to get consistently represented in the Arrange window. To get that, Logic would have to allow the region start and end to be between ticks, and it won't allow that--something has to give.
Here's what actually happens: you set the anchor with sample accuracy in the Sample Editor, then you place the region in the Arrange to be at exactly bar 5 (5 1 1 1 1), for instance. You'd expect the anchor to be at exactly bar 5, but it isn't... it's close, but what Logic actually does is line up the region by the region start marker. The region start marker never moves relative to the region's audio: when you try to put the anchor at bar 5, Logic actually slides the region to the nearest tick value--the start marker goes precisely on a tick, and the anchor ends up slightly ahead or behind the bar 5 marker.
Now, this behavior isn't so bad in most cases--can you really hear a few samples difference between exactly where you put the anchor, and exactly where it ends up ? Almost certainly not, although I know an obsessive-compulsive post editor who isn't going to be happy when I tell him this...
But the dark side of this behavior occurs with the region end point. Again, Logic never moves the region start relative to the region's audio--it shifts around the anchor to make the region start fall on a rounded tick. But what about the region end ? Unfortunately, even though the Sample Editor will let you put the region end anywhere you want it, and it will save the region/file that way, that region end will get shifted around to fall on the nearest tick in the Arrange.
So, you cut a sample precisely in the Sample Editor, make sure the start and end fall on zero crossings, then you place the anchor at a transient point and spot the region in the Arrange. What actually happens is that
1) your start region edit gets preserved
2) the anchor gets put somewhere fairly close to the actual spot point
3) the region end gets rounded to the nearest tick
#1 is great, #2 probably OK, but #3 can be a problem. Your region may sound great in the Sample Editor, but it may click on the back end in the Arrange... unless the region's start and end happen by luck to be exact tick multiples of each other, the region end will get moved by a few samples, which may cause a glitch in playback.
My suggestions:
1) Be aware that anchor's aren't placed with sample-accuracy. You probably will never care, but it's good to know.
2) Leave a tick or two of silence at the end of a region. If you use a Sample Editor to trim the region end precisely to a zero crossing, you'll probably get bitten when you put this region in the Arrange. Either do a destructive fade in the Sample Editor, or use the fade tool in the Arrange. (DAWs are going to have to take a few more steps forward before we can stop being superstitious about fading the start and end of every single region, even when edits are at zero-crossings. If the work is important, crossfade everything!)
3) Apple... PLEASE, PLEASE, PLEASE revamp the Arrange window to be sample-accurate. There are so many kludgy little issues that would go away if the base timescale could be samples. Not to mention that almost every other DAW has this...

iSchwartz,
Serves me right for not doing a listening test.
Turns out that you're entirely right about what actually gets played back. I did a few tests by aligning two regions, phase-canceling them, then moving around the start, end, and anchor points.
Sure enough, what I HEARD corresponded exactly to what I saw in the Sample Editor.
But the Arrangement doesn't show things that way--I was looking instead of listening, and in these cases, the Arrangement can show things that are contrary to what gets played back.
When you move that end marker to the right in the last step of your test, I'll bet the Arrange window doesn't show the little glitch that you're now able to hear. And if you take an Arrangement region that ends with a little glitch, you can remove it by sliding the region end a sample to the left in the Sample Editor, but you'll still SEE the glitch in the Arrange window. Looks like the Arrangement plays back exactly what you've got in the Sample Editor, but it DISPLAYS things rounded to the nearest tick.
And this gets more confusing when you move around the anchor point. Trim one of your clicks so the anchor and the region start are both precisely on the transient, and move that region to a bar marker. Then look at the Arrange window at maximum zoom--you'll see exactly what you'd expect.
But... now... go back to the Sample Editor and try moving the anchor a few samples to the right. When you go back to the Arrange window, nothing has changed--the transient still looks like it's precisely on the bar marker, while the Sample Editor shows that it's not.
And it gets weirder... go back to the Sample Editor, and move the region start a few samples to the left. Now, when you go back to the Arrange window, what you see is exactly the opposite of what you'd expect. You'd expect the anchor to have stayed put, and the region start should have moved. Instead, the region start is still at the bar marker, but the audio inside the region appears to have moved.
This is why I was so confused about what was going on. You're completely right about the playback--I did some tests, and all this strange behavior I'm seeing in the Arrange window, none of it makes it to playback. When the Arrange window and Sample Editor disagree, the Sample Editor seems to be ALWAYS right.
But when you start doing sample-accurate editing with the Sample Editor, the Arrange window no longer reflects reality--region start and end markers appear to be on at rounded ticks, even though they're not, and audio will appear to be displaced within regions, even though it's actually lined up perfectly by the anchor.
Just goes back to point #3... it's kludgy crap in the Arrangement resulting from the tick timebase. Logic 8 ?

Feature Request: Destructive editing with AUs in Sample Editor

I would like to be able to apply edits destructively in the sample edit window with Audio Units like we could in Logic on MacOS9 (which used AudioSuite plugins). This is an ongoing request, year after year, among veteran Logic users. In every update it is ignored. The feature requires no redesign of the sample edit window, just another menu sub item droplist. While the bounce in place feature is a welcome addition, it is not a replacement for this feature that was removed in the migration to MacOSX and has been sorely missed ever since.
Here's just one recent sentiment from a user on the NYC Logic Users Group:
"I recently changed over to Logic from Pro Tools and I really miss this feature! For handling plosives and de-essing small fragments."
I also know a very prominent producer who boycotted Logic 8 and 9 for this reason alone. While I would never do that (since I happen to love all the new features and feel comfortable with the workflow of Logic 9), I sympathize with this person's frustration over the lack of this feature. I find myself constantly in the position of wishing I had destructive editing back in my Logic tool belt.

With all due respect, I personally cannot stand soundtrack. A lot of effort was put into the app that should have gone into Logic. As you allude to, I can trigger that Logic keystroke to open any sample editor, which is what I do. I just want the functionality back that was taken away from us many moons ago. I'm not looking for workarounds. This is just a simple feature request. But thank you for the suggestion.

Editing in sample editor

No destructive editing using installed plug-ins in the sample editor.

It is a shame that it looks like there still is no destructive editing using installed plug-ins in the sample editor. Seems very obvious to me that this feature should be included in Logic. Very disappointing. I’m assuming that you will be able to do this via Soundtrack Pro, but that’s just another layer added to the work flow.

fermusic wrote:
in any case there are no reason to use Soundtrack pro for make a destructive editing with AU plugins.
While everything you say is absolutely correct, in terms of being able to do this within Logic itself, there are times when using Soundtrack Pro does make more sense for destructive printing of AU FX's.
High pass filtering a vocal track with a lot of plosives comes to mind. It's easier to destructively apply the AU high pass filter on just the plosive syllable, or waveform in STP, than in Logic.
Same goes for some extreme cases of De-essing.
With STP selected as your external audio editor, it's very easy to use from within Logic. The two co-exist quite gracefully.
I'd personally love to see Logic adapt some of STP's destructive capabilities, and I'd actually be surprised if we didn't see that at some point in it's evolution.
But I say none of this to dismiss what you've generously offered here. The information you provided in your first post is important for the Logic novice to be aware of.

Sound disappeared from Sample Editor?

Can anyone help? The sound has completely disappeared from my Sample Editor window and also the Audio bin.
I can't audition any loops in the list now, but if I drag them to a track in the main Arrange page they play fine. Then double clicking on that Audio loop or any audio clip in Arrange to bring it up in the Sample Editor window shows the waveform okay, but playing it just goes through the motions with the cursor moving as normal but no sound. Dead. Nada.
Is it me? I am not a novice with Logic but I can't work this out. I tried throwing away the preference files in Library/Prefs but nothing doing.
Any help would be appreciated as I can't edit in Logic now like this.
Cheers
Musolen

Well thanks again Chorleyman,
I have had a play around and added another Audio strip in the Environment, set it to Output No.256 (The highest) and the Sound in the Sample Editor came straight back on. It's still called Audio and not PreListen, I can't seem to rename that, but it works now so I have my solution.
Thanks again for the advice and to everyone else reading this and mulling it over.
Cheers,
Musolen.

Exporting from the Sample Editor

Ambition: To lift a brief sample from an Aiff file to use in an arrangement.
So far I have the sample in the sample editor, and the portion of the sample I wish to use highlighted. (I can even play it looped using the loop function)
My question:
How do I get this small 4 sec. slice of the 3 min. Aiff file on its own? And how do I export it for use in later, perhaps unrelated projects?
Thank for any help!

hi, once selected(in sample edit) go to audio file menu - save selection as....
also, this can be done and is reflected in the said region in the arrange.
edit region, then local audio menu - save region as audio file...

None of the functions in the sample editor are appearing

Every time i go to the sample editor the editing functions are all greyed out, with the exception of gain I am using some of the logic content
Is there an easy way around this? Did I not correctly install the au stuff?

sounds like you are editing an apple loop. those cannot be modified without bouncing the loop in the arrange, and reimporting it

STPro as Logics sample editor.

I like to use STPro as Logics sample editor in certain cases. However, one thing has me stumped.
Does anyone know how to get STPro to show up the sample in beats, when I (launch external sample editor' in LogicPro?
I have the preferences set to show 'Beats' in new documents, but it always defaults to min:secs....
Anyone have any ideas...? I would love to be able to edit accurately in beat mode.

The beat option only seems to be available from the multi-track vantage point. For instance you can't add a beat marker in the sample editor - the tool is greyed out - and if you've set some b-markers in the multi-track view, they're not visible any longer in the editor view. And yes, this drastically limits the usefulness of SoundTrack when setting up audio loops for example, and, of course, this is not discussed in the manual.

Wierd issue with Sample Editor...

Hi again! More questions to use this program efficiently without pulling all my hair out... When I'm using the "time and pitch machine" under Factory in Sample Editor, I've run across an issue. I got a sample to loop accordingly Trimming off the rest of the song in the sample, then I Changed the BPM from about 240 to a new destination of 220 just to shake things up. When I did this, I wasn't too happy with the sound afterall, so I simply chose UNDO from the edit menu.....and now, there is an extra piece of the loop that was added to the end of the loop... that I can't get rid of! Undo can't undo? What gives?
Secondly, It has a function to "pre listen" in the menu of the time machine... yet when I hold the mouse down to preview it... It simpy plays back the exact tempo it was originally without any change reflected. The Help file says some audio hardware it will work with... I'm using a MOTU 2408MK3, I figured this could handle a simple task. Anyone have this issue or suggest anything?
- Thanks for all the help guys!

logic need to improve on that, its been like this since it was first introduced
it works well with short samples/loops and it works well with different algorithm
so try all of them
also you can turn your loops into apple loops, it works better sometimes like that
the other choice is to export that loops and import it back again, so that logic can activate the follow the tempo on it

that works if the sample is playing whilst you are dragging your mouse to move the blue ball around

Editing Loop Start and End times via automation / MIDI controllers?

I'm trying to play a sample in EXS24 and have the Sample Start, Loop Start and End times manipulated over the course of the song. I've tried to open up the EXS sample editor, click on the numerical value of the Loop Start, and then attempt to Learn Automation. All it does is assign the knob for the instrument Volume Level. Is there any way to do this? It's basically how an Akai S612 works: http://www.vintagesynth.com/akai/s612.shtml
I switched gears and tried it also with Battery, and there's a way to map the Start and End times in there, but it's not seeming to work as I've intended. I can't seem to make the loops move as they should and there's ways to use up to 4 loops, but not a way to target each loop's start and end points via separate controllers.
I could use my S-612 [and probably will], but in moments where I don't have one available, I'd love to find a solution to this.
Thanks,
+odd

Anyone with any thoughts? would be great to solve this.
