Yamaha VL70-m User Manual

The modifiers block consists of 4 sections as shown in the diagram. Although
these may appear to be simple effects, they are actually intimately related to the
VL70-m’s sound-producing model and have a significant effect on the sound
(the VL70-m has a separate effects stage with reverb, chorus, variation, and
distortion effects — see page 86).

● Harmonic Enhancer
The Harmonic Enhancer determines the
harmonic structure of the sound to the
extent that it can produce radical timbral
variations within an instrument “family”
(e.g. saxes). The harmonic enhancer param-
eters can be accessed via the Yamaha VL70-
m Expert Editor software (page 25).

● Dynamic Filter
This section is similar to the dynamic filters
found in many conventional synthesizers,
with high-pass, bandpass, band elimination,
and low-pass modes. Some filter parameters
are available via the VL70-m controls, but
detailed editing of parameters such as the
filter type requires the Yamaha VL70-m
Expert Editor software (page 25)

● Frequency Equalizer
This is a 5-band parametric equalizer with frequency, Q (bandwidth), and level
control. The equalizer also has pre-EQ high- and low-pass filters as well as key
scaling capability for precise response control throughout the instrument’s
range. Although only simplified treble and bass parameters are available via the
VL70-m controls, the full range of equalizer parameters can be accessed via the
Yamaha VL70-m Expert Editor software (page 25).

● Resonator
The Resonator uses simulated “resonator” pipes or strings and delays to produce
a “woody” resonance effect — although it has little or no effect on some voices.
The resonator parameters can be accessed via the Yamaha VL70-m Expert
Editor software (page 25).
