Creating New Regions

When editing audio, you will often need to select a portion of a region and delete it, move it somewhere else, or make multiple copies of it. For example, you may want to make multiple copies of a bass line to create a bass loop that repeats during a song’s verse. In Pro Tools, there are several ways to select a portion of audio and create a new region, including capturing a new region, separating a region, or using the Separation Grabber tool.

I usually create a new region by selecting a portion of an existing region with the Selector tool and choosing Separate Region from the Edit menu (or typing + E [Mac] and Ctrl + E [Win]). This command creates new regions by separating and renaming the affected regions on the playlist. Additionally, if you’ve placed the cursor somewhere on a region but haven’t selected any part of it, the Separate Region command will split the region right where the cursor is. It is beneficial to automatically separate a region like this if you know you want to cut out and/or move the region, because it makes the region easier to select, grab, trim, move, or delete. I also recommend learning how to use the Separation Grabber to perform region separations.

 


Cut, Copy, Paste, and Clear


If you’ve used any piece of software (like a word processor or spreadsheet) other than Pro Tools, you probably have cut, pasted, copied, and cleared data before. Those actions are no different in Pro Tools, except that you are cutting, pasting, copying, and clearing audio or MIDI data instead of text or graphics. These commands are very useful for editing and can be used to edit any type of track material. The Track View determines what type of track material (e.g., volume data) is cut or copied from a track. Remember that you’ll cut or copy all data that accompanies a track in its Master View, as mentioned previously.

As with most editing functions, the current edit mode determines how track material is affected by an editing action.

DIGITAL EDITING TECHNIQUES

When cutting and splicing analog tape, you rely solely on your ears to find musical edit points. There are often hundreds of pieces of tape to keep track of and all razor-cut edits are destructive. It is an exacting and exhaustive process that yielded good results for several decades. However, it’s fast becoming a dead art since digital editing has forever changed the way we think about production.

One of the best features of editing digital audio (in my opinion) is that you actually see the waveform you’re trying to edit; you’re able to combine your senses (hearing and sight) to get the job done. Obviously, music is heard, not seen, so we must continue to rely heavily on our ears to make sure anything we do sounds good. However, for visually oriented people like me, being able to see what I’m listening to helps me find accurate edit points much faster. In fact, most people rely on sight as their primary sense . . . even musicians.

With its variety of functions, there’s really little you can’t do in Pro Tools when editing audio or MIDI. In fact, because Pro Tools offers so many ways to edit your music, every Pro Tools user seems to utilize different techniques and functions to get their work done — an entire book could be written on Pro Tools editing techniques alone. That said, I’m going to cover just a few of the functions I use regularly.

Additional information on all of the editing features of Pro Tools can be found in the Pro Tools Reference Guide and on the Digidesign Web site. I also recommend getting together with other Pro Tools users and exchanging tips — you’ll be surprised how much you can learn. (Visit Digidesign’s User Conference area or the DigiZine on their site for access to a knowledgeable and vibrant community of Digi users, from newbies to top pros.)

In its most basic forms, Pro Tools editing is cutting, pasting, copying, and clearing regions and files; being familiar with these commands is imperative. Editing also involves dexterity in creating regions, capturing regions, locking regions, placing regions in tracks, and sliding regions so you can manipulate them comfortably.

Usually I learn new editing techniques when forced to do so. For example, I needed to figure out the best and fastest way to comp a vocal part together. So I paged through the reference guide for information, asked some friends, and sussed out a few different techniques. After trying several methods, I chose to comp vocals using playlists because it worked best for my recording and editing needs. This technique might not be the technique that someone else would use first, but it works well for me. The moral: Don’t feel like you have to be a total Pro Tools expert to edit like a pro. You can learn as you go!

Comping Using Playlists


Fig. 4.9. Click on the arrow next to a track name to select or create a new playlist, then name the playlist.

“Comping” is the process of combining all the best parts from multiple takes into one master take. As I mentioned in chapter 2, I like to record multiple takes of tracks, particularly overdubs such as vocals or guitar solos, on new playlists on the same track. That way I can compare the parts I like from each and easily edit them to create a master take.

To me, copying and pasting among takes on separate playlists is the fastest way to comp together the finished product because (a) it’s not necessary to create or separate any regions (Pro Tools automatically creates them) and (b) the same selected audio or MIDI area stays selected when changing between playlists, making seamless comps a breeze.

To create a playlist for a new take, choose New from the Playlist selector and name the file accordingly (as in figure 4.9). To copy and paste between takes, select and copy the audio or MIDI area that you want from one playlist, then choose the “target” (master take) playlist using the Playlist selector and perform a paste — Pro Tools automatically creates a new region for the pasted part. If you need to create a crossfade between regions on a newly comped track to smooth out the sonic transition between two regions, choose Fades then Create Fades from the Edit menu (more on fades and crossfades in the section that follows).

FADES AND CROSSFADES

A huge part of making your edits sound natural is your ability to use crossfades. Crossfading is the process of fading two regions of audio together to prevent pops, clicks, or sudden changes in sound. Crossfades have many applications, from smoothing transitions between regions to creating special audio effects.


Fig. 4.10. The Fades window takes the pain out of creating seamless transitions between regions.

Pro Tools makes it easy to create your own fades and crossfades. For those who’ve edited analog tape, you know you’re basically limited to choosing one of a few different angles of tape cuts to create crossfades. But with Pro Tools you can actually draw your own crossfade curves and listen to how they sound, or choose from Equal Power, Equal Gain, and any of a number of different curves as seen in figure 4.10. You can even apply dither to fades.

Note: When you’re working with 24-bit files I recommend using dither on crossfades if levels are low, and that you always use dither on fade-ins and fade-outs. (Dither is fully explained in chapter 13.)

THE EASY WAYS TO FADE

As with most other major functions in Pro Tools, there are keyboard shortcuts that make creating fades easier. To access the Fades dialog box, simply type + F (Mac) or Ctrl + F (Win). And even easier... to apply a crossfade to a selection without accessing Fades window at all, do this:

+ Ctrl + F (Mac) This uses the default fade shape defined in the Preferences.

Ctrl + Start + F (Win) This uses the last fade shape that you selected.

And remember, you can also use the Smart Tool to create fades and crossfades. First, place the Smart tool near the beginning or end of a region. Then, to create a fade, mouse to the upper half of the track and the fade icon will appear. Click and drag where you want the fade to begin and end. Similarly, if you want to create a crossfade, mouse to the lower half of the region and
the crossfade icon will appear. Click and drag where you want the crossfade to begin and end.

Nudging Notes
Sometimes you’ll record a great take but one or two notes are just a bit out of time. A good example of this is when a bass player hits a downbeat slightly ahead of when the drummer hits the kick drum. (I’m not implying that bass players tend to rush; they just get overly excited sometimes.) To fix the syncopation, you can nudge the bass note slightly later in time to match the kick downbeat.


Fig. 4.11. Use the Nudge dropdown menu to easily move selected regions without having to mess with ultra-accurate mousing.

To nudge a note or several notes, first find the note(s) in the waveform in the Edit window. Zoom in close enough so you can see where the note begins and ends. Select the note(s) and create a new region by choosing Separate Region from the Edit menu. Now select the nudge value from the Nudge dropdown menu in the upper-right corner of the Edit window. You can choose from Bars:Beats, Min:Secs, or Samples. Pro Tools offers a list of values for each of these, but you can type in your own if you want. I recommend trying 10ms as a starting point and adjusting from there. Press the plus key (+) on the numeric keypad to move your selection forward by the nudge value or the minus key (–) to move the selection back. You may have to press either key several times to align the bass note with the kick drum.

And if you want to get really fancy… If you nudge while pressing Control (Mac) or the Start key (Win), you can actually nudge the contents of a region without changing the region’s start and end points. This only works if there’s audio or MIDI material outside the region’s start and end points. (It would work in our bass/kick drum example and could possibly yield slightly better results.) You should also note that the Nudge command works the same regardless of the Edit mode you’re using at the time.

Be careful using the nudge editing technique though. You can go crazy trying to align every note, killing way too much time and taking away from the real performance — the “vibe” — of the part. If the part needs that much fixing, re-record it!
