Set the range for the basic bass sound in Sculpture
To more realistically replicate the different tonal ranges of the bass, use the scaling
function.
When turned on, the key-scaling function is used to adjust the timbre of the sound,
independent of pitch. Before using the blue sliders to do this, try the Resolution parameter.
• In Logic Pro, click the Keyscale button at the bottom of the Material Pad. The key scale
below C3 is displayed in green, the range above in light blue. The Material Pad with its
Keyscale parameters activated is shown here:
Note: The most relevant performance range for basses is found exclusively below C3.
For this reason, you should make use of the green sliders to set the actual timbre of
the sound. The primary sliders found around the ring determine the timbre of the sound
above C3. For the moment, ignore the blue sliders (which control high key scaling) and
simply set them to the same positions as the main sliders.
Refine the basic Logic Pro Sculpture bass sound
This section covers modifications to the basic bass sound. See Program a picked bass
sound in Sculpture, Program a slap bass sound in Sculpture, and Program a fretless bass
sound in Sculpture.
Sequentially follow the tasks in this section after reading Program a basic bass sound in
Logic Pro Sculpture to learn how different components can be modeled and to gain a fuller
understanding of how Sculpture parameters interact.
Use the Resolution parameter to control the timbre, independent of pitch in
Sculpture
The Resolution parameter is normally used to set the balance between DSP load and sound
quality. It can, however, also be used to shape the sound.
1. In Logic Pro, play some notes at the higher end of the bass range (around C2), then
drag the Resolution slider all the way to the right and then gradually back toward the
left.
You can hear how the sound loses overtones yet simultaneously becomes louder. At low
Resolution values, an inharmonic metallic rattling is heard in the sound.
