Mixing & The Modifiers
Although any modulator source signal can be applied to any carrier source signal,
two approaches are recommended when attempting to create an acoustic instrument
simulation.
The first is to set the carrier signal to “Normal” and the modulator signal to any
other than normal, set the dry/wet “Balance” to 63 (all wet), and set a relatively high
modulator “Index” value. In this case the total output of the instrument model (“Nor-
mal” signal) will by modulated by one of the component signals, so the dry/wet “Bal-
ance” can be set to fully wet (modulated carrier output only) since the carrier source and
dry signals are essentially the same. The “Index” parameter determines how much
modulation is applied, so a higher value is generally required to create sufficient varia-
tion. The second approach is to set the carrier signal to any other than normal and the
modulator signal to any of the six possibilities, set the dry/wet “Balance” to a more
central value, and set a relatively low modulator “Index” value. In this situation it is
necessary to set the “Balance” more toward the “Dry” side since the carrier source
signal is not the normal signal and at least some of the dry signal is necessary to provide
the basic sound of the instrument model. In other words, the sound produced by the
Harmonic Enhancer is simply added to the basic sound of the instrument, in contrast with
the first approach in which the basic sound of the instrument is modulated directly.
Please note that these are only guidelines, and are by no means the only way to
work with the Harmonic Enhancer. Since the Harmonic Enhancer tends to respond
differently with different instrument models, experimentation and experience are your
most valuable tools.
While the “Balance” and “Index” parameters apply to the overall harmonic
enhancer sound, the following independent parameters are provided for the modulator and
carrier blocks.
Both the modulator and carrier blocks have high-pass filters that can be
used to roll off the low frequencies of the corresponding signal. The
cutoff frequency can be varied from 17.0 Hz to 11.2 kHz.
This parameter boosts the corresponding modulator or carrier signal,
forcing it into distortion and thereby drastically changing its harmonic
structure.
This parameter is provided for the modulator block only. It allows a
degree of timbral variation by varying the phase of the modulator signal
through 360 degrees in 2- or 3-degree increments.
Look at the Harmonic Enhancer display pages again. Parameters with an inverse
“K”(˚) next to them can also be controlled by key scaling — i.e. the value of the param-
eter changes according to the pitch of the key played. This makes it possible to achieve
both natural and unprecedented timbral variations across the range of the keyboard.
