7. You’ll quickly realize that you can achieve a precise, crisp sound only when you drag
the slider relatively far away from the middle of the string. Move Object1 closer to the
pickup (position 0.15 in the figure below).
8. The low notes are still distorted. You can remedy this by adjusting the Level knob to the
right of the amplitude envelope. Set a value of −10dB.

Although you can already recognize the sound of an electric bass, it doesn’t sound wiry
enough yet. Now it’s time to focus on the bass strings themselves.
1. In Logic Pro, drag the ball in the Material Pad up and down at the left edge. Pay
attention to how the overtones react.
Drag the ball to the lower-left corner. The sound should vaguely remind you of the
sound of a low piano string. Because the overtones sustain too long, the tone sounds
somewhat unnatural.
2. Drag the ball upward until you hear an acceptable sound. Try the position shown in the
figure:
Note: In general, a splaying of the overtones in low wound strings is typical. You can
recognize it by the slightly impure, metallic sound. This occurs because the partials
(overtones) are not exact whole number multiples of the fundamental frequency but rather
are shifted somewhat higher. An example of this effect in the real world of electro-acoustic
instruments is the low strings on a Yamaha CP70. This is overkill, but your bass model may
benefit from a small amount of this effect.
