The Modifiers

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 parameters 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

Resonator

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).
