Resolution slider: Determine the precision of the calculation. High values produce extra
harmonics. Low values produce fewer harmonics, or inharmonic spectra.
Use the Ultrabeat Material Pad
The combination of the Inner Loss and Stiffness parameter positions determines the string
material and, therefore, the general timbre of your sound. In general synthesizer terms, use
of these parameters could be viewed as being similar to the waveform selector/generator in
the oscillator section. The default pitch of the string is C3 (middle C).
In Logic Pro, you can simultaneously adjust the Inner Loss and Stiffness parameter
positions by dragging the ball (which correlates to the x and y coordinates) in the
Material Pad.
Low Stiffness values, combined with low Inner Loss values, lead to metallic sounds.
Increase the Stiffness to make the sound more bell-like, or glass-like. Extreme
Stiffness values turn the string into a solid metal rod.
Increase the Inner Loss value while maintaining a low Stiffness level to emulate nylon
or catgut strings.
High Stiffness values, combined with high Inner Loss values, simulate wood-like
materials.
Note: Option-click the ball to reset all string parameters to their default values.
Logic Pro Ultrabeat ring modulator
Ring modulation is a powerful tool for the creation of inharmonic, metallic, bell-like sounds.
The Ultrabeat ring modulator functions as an independent sound source—its signal can
bypass or be sent into the filter, independent of the oscillator1 and 2 signals. Its volume
can also be regulated.
Important: Although the ring modulator signal is independent of the signals generated
by oscillators 1 and 2, both oscillators need to be enabled if you want to use the ring
modulator signal. Because the ring modulator is reliant on the signals of both oscillators
to produce an output signal, it is automatically muted when one of the oscillators is
switched off.
The actual sound produced by the ring modulator is largely dependent on the parameter
settings of both oscillators. In particular, the tuning relationships of each oscillator have
a direct effect on the sound of the ring modulator signal. The individual levels of the
oscillators, however, have no effect on the process (or output) of ring modulation.
