Week 124: “Percussivate” Your Parts A tried-and-true technique to impart rhythmic characteristics on a part is to use side-chaining. For example, if you feed a pad into a gate and use a drum part as the gate's sidechain signal, you can “chop” the pad so it follows the drums.
However, the Loop Construction View has yet
another little-known talent that can let you “percussivate” any part. This technique can do all kinds of other tricks, like make it easy to create “faux” REX files, but for now let’s look at how to take a heavily compressed power chord and make it pulse rhythmically.
But first…go to Preferences and choose
Customization > Editing > Clips > Right Portion for “Selection after Single Split.” You’ll see why this is important in Step
8 below.
1. Make sure the Clip you want to “percussivate” has a defined number of beats.
2. Double-click on the Clip (the default double-click behavior for Clips) to open it in the Loop Construction View.
3. Click on the Loop button and verify that the Beats field shows the correct number of beats. Note: This may appear to truncate the clip in the Track View. Never fear—simpily slip-edit the Clip's right edge to show the entire clip.
4. Use the drop-down menu below the Slice drop-down menu to choose the "pulse rate," as shown by where the transient markers fall. The screenshot shows quarter notes, but you can also choose “No Slice” to add markers wherever you want (by double-clicking just above the Loop Construction View’s “time ruler") to create polyrhythms and syncopations.
5. You can close the Loop Construction View once you’ve placed your markers where you want.
6. Click the Clip to select it, and place the Now Time at the beginning.
7. Press Tab. This places the Now Time on the first transient marker. Type
S to split the Clip.
8. Keep hitting Tab and typing
S until there are splits on all the transient markers. This is why you want to select the part of the clip to the right of the split in Preferences—typing S won’t add a split unless the region you want to split is selected. The screen shot shows what the Clip looks like when you’re halfway through the process.
9. Drag across all the slices to select them all. Now if you add a fade to one slice, you’ll add it to all of them.
10. You may need to add a very short fade in as well to prevent clicks. This only has to be a couple milliseconds, so it's not necessary to compromise the sound's percussive nature.
11. To make these changes permanent, and turn the loop-based clip into a standard clip, bounce the clip to itself (i.e., with all the slices selected, choose
Clips > Bounce to Clip(s) in the Track View menu).
And there you have it—your "percussivated" power chord!
But...what good is a "Friday's Tip of the Week" without a
"But wait! There's more!"? Please note that this tip shows a very basic application. For example, while you’re in the Loop Construction View, you can also change the pitch, pan, and level of each slice to do “audio step sequencer” effects, as described on page 203 in “The Big Book of SONAR Tips.” You can also split a Groove Clip into its constituent parts to create "faux" REX files without using AudioSnap, split REX files and shuffle the slices to create variations on a loop, and more. Is it any wonder I feel the Loop Construction View is one of SONAR's most under-exploited features?
