The pad now has a pleasant and unobtrusive ambience; you can leave the other Delay
parameters at their original values.
Make the sound more lively using the jitter modulators in Sculpture
You can make the sound more animated with some subtle modulation, which makes the
jitter modulators the perfect tool for the job. The jitter modulators are basically LFOs that
use a random waveform.
1. In Logic Pro, click the Jitter button below the LFO section to activate the display for
both of the jitter modulators.
2. Click the 1button to turn on the first link in Jitter 1, and choose Object1 Timbre from the
Target pop-up menu.
3. Drag the slider below the Target pop-up menu to −0.40 to adjust the Intensity, and
reduce the Rate parameter to 1Hz. There should be subtle inconsistencies in the
pressure applied by the bow to the string. To better recognize this effect, temporarily
increase the Intensity level.
You can use the second jitter modulator for random position deviations with the
modulation target Pickup PosA+B (pickup position A and B).
4. Activate Jitter 2 and choose the Pickup PosA+B setting from the Target pop-up menu.
5. Drag the slider below the Target pop-up menu to an Intensity of about 0.2, and adjust
the Rate knob to 1.5Hz. As you increase the Intensity, the sound develops a distinct
clinking or rattling—adjust this effect to taste.
You now have a satisfactory pad sound, which you should leave alone at this point, even
though a few Sculpture features such as the Filter and the Waveshaper lie idle—not to
mention the two additional Objects—but sometimes it’s a good idea to quit while you’re
ahead.
