Effect Parameters - Yamaha S70XS Reference Manual

VCM (Virtual Circuitry Modeling)
VCM is a technology that enables you to model element levels in analog circuits (such as resistors and
capacitors). Effect types using the VCM technology produce the uniquely warm characteristics of
vintage processing gear.
This instrument features the following eight VCM Effect types.
VCM Compressor 376
This effect emulates the characteristics of analog compressors, which are used as a standard effect in
recording studios. It frames and thickens the sound, and is suitable for drum and bass sounds.
VCM Equalizer 501
This effect emulates the characteristics of analog equalizers used in 1970s. It adds drive to the sound
by reproducing distortion typical to analog circuits. This effect consists of two shelving filters and three
peaking filters.
VCM Flanger
This effect emulates the characteristics of analog flanger used in the 1970s, recreating a warm, high-
quality flanger effect.
VCM Phaser Mono, VCM Phaser Stereo
These effects emulate the characteristics of analog phasers used in the 1970s, recreating a warm, high-
quality phaser effect.
VCM Auto Wah, VCM Touch Wah, VCM Pedal Wah
These effects emulate the characteristics of analog Wah used in the 1970s, recreating a warm, high-
quality wah-wah effect.
REV-X
REV-X is a reverb algorithm developed by Yamaha. It provides high-density, richly reverberant sound
quality, with smooth attenuation, spread and depth that work together to enhance the original sound.
This instrument features two types of REV-X effects: REV-X Hall and REV-X Room.

Effect Parameters

Each of the Effect Types has parameters that determine how the Effect is applied to the sound. A variety of sounds can
be obtained from a single effect type by setting these parameters.
For information about the Effect parameters, see below.
Preset settings for Effect parameters
Preset settings for parameters of each effect type are provided as templates and can be selected in the
Effect Type selection display. To get a desired effect sound, try first selecting one of the Presets close to
your imagined sound, then change the parameters as necessary.
To get a desired effect sound, try first selecting one of the Presets close to your imagined sound, then
change the parameters as necessary. For details about the preset settings of each effect type, refer to
the Data List (separate PDF documentation).
