Once activated, the key-scaling function is used to adjust the timbre of the sound,
independent of pitch. To do this, we’ll initially employ the Resolution parameter. This is
normally used to set the balance between DSP load and sound quality. As the over-
tone spectrum is reduced at low Resolution values, this parameter can also be used to
shape the sound.
To use the Resolution parameter to control the timbre, independent of pitch:
1 Play some notes at the higher end of the basss range (around C2), then move the Reso-
lution slider all the way to the right and then gradually back towards the left.
2 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.
3 Increase the Resolution value until the metallic rattling disappears. We recommend set-
ting the slider to the following position:
4 Play some notes in the bottom range (around E 0). You’ll note that the sound is quite
muffled and vintage-like. Move the green Low Keyscale slider (found below the main
Resolution slider) all the way to the right; the low range should now sound a little more
“wiry.
With most stringed instruments, the overtone content decreases as the pitch becomes
higher. Strictly speaking, this is only true of open strings, and even then, in a limited
sense. If the strings are fingered, the length of the string is shortened (especially in the
high register) and the effect becomes more significant.
This is why we use the Inner Loss parameter to scale the overtone content,
dependent on pitch:
1 Move the Material Pad ball above the words Inner Loss. Try to move the ball solely in a
vertical direction, in order to maintain a constant Stiffness value.
2 Grab the green line next to the ball, and pull it towards the bottom until the small
green diamond is located directly above the word Steel.
