Splay overtones in Sculpture
1. In Logic Pro, drag the ball in the Material Pad gradually to the right.
The sound takes on a more pure, bell-like character.
2. To realistically simulate the splaying of overtones, try the following example setting:
Emulate string and fret vibrations with Object2 in Sculpture
The vibration of a bass string does not occur in a vacuum. The antinode of the string
frequently encounters the natural, physical limitations of the instrument. This is heard as
the typical buzzing and rattling that occurs when the strings touch the frets.
1. In Logic Pro, activate Object2, and choose Bouncing from the Type pop-up menu.
The sound should now vaguely remind you of a mandolin tremolo. This is far too strong
an effect for this kind of sound.
2. Move Object2 all the way to the right (a value of 1.00).
3. Experiment with Object2 parameters. A discrete and realistic result can be achieved
with the following parameter values:Strength 0.33, Timbre −1.00, and Variation −0.69.
Play some low notes, and you’ll find that once again the overtones sustain a little too
long—somewhat like the lowest notes or strings on a piano. this can be corrected by
dampening the string.
Use Object3 to dampen overtones in Sculpture
1. In Logic Pro, activate Object3 and choose Damp from the Type pop-up menu.
2. Move Object3 all the way to the right (value 1.00).
3. Set the Strength parameter to 0.18.
Note: Experiment with how the Strength parameter of Object3 interacts with the Inner
Loss Material Pad parameter. The higher the Inner Loss value, the smaller the Strength
value can be, and vice versa.
