One more question about "snap to" points in audio objects

Question

sorry, one more question people.............. is there a way to set a "snap to" point in an audio region? Can I have logic set a point, or an "anchor" within an audio region that would coincide with the cursor. Once I get the cursor to a bar or a beat, is there a command that would allow a "snap to" point to be created in an audio object? That way I could clean up any "noise" or "chatter" at the beginning of an audio bounce or any audio object, and still have no problem pasting it all over my arrangement. I'm sure it's in here somewhere, but can't find it in the manual..
thanks again!!!

Answer 1

The anchor point in an audio region can be moved to wherever you want it to be. Let's say you recorded a loud piano bass note and afterwards you trimmed the file so that the attack of this sound happens right at the beginning of the audio region. Your anchor point will now coincide with the begnning of that region. This means that you can place that audio at, say, bar 37 and it's guaranteed that the attack of that sound will play exactly at bar 37. In this case anchor point = position of audio region in the Arrange Window.
Even though you haven't played a MIDI note into the song in order to place this audio region, an "event" is generated for this sound which can be viewed in a special version of the Event Editor which shows the position of all audio regions in the arrangement. Access this by simply clicking on a blank area of the Arrange window and then opening the Event Editor.
So let's say this sound is positioned at bar 37. Open the Event Editor (as described above) and you'll see an event at 37 1 1 1 and the name of that audio region to its right. In this case, the event's position = the start of the sound file = the position of the anchor within that sound file. If you changed the position of that event to 38, or 109, or 3, that audio region will be "triggered" at any of those positions. That sound will always "attack" on a downbeat.
Now let's say you reversed that pinao note in order to create a dramatic swell into a section of your song. (Open the sample editor and use the Reverse function). At this point, the anchor point is still positioned at the beginning of the file! Play back the sequence (from our bar 37) and the audio will play back from bar 37, only backwards this time; the peak of that piano note will be at some point later than 37.
So let's say you wanted to position this sound so that it hits exactly on the downbeat of bar 37. How do you do it? Well, you could always slide the audio file in the Arrange Window and try to line up the attack of the audio waveform with the downbeat of bar 37, but there's an easier way...
Open the sample editor and move the anchor point to the end of the file, coinciding with the peak of the waveform (the piano's attack is now at the end because we reversed the audio). Next, close the sample editor window, click on a blank area in the Arrange Window and open the Event Editor. You'll see that this audio region is still positioned at bar 37, but the actual beginning of the sound file now starts before bar 37. Now when you play back, Logic will start playing that sound file before bar 37, but the audio's peak will be lined up at bar 37.
