Applying Vibrato or Tremolo LFO, LFO1LFO2 Wave

T1–T4 (TVA envelope time 1–4)

These settings determine the times over which the Tone level setting will change from one TVA envelope level to the next.

L1–L3 (TVA envelope level 1–3)

Each TVA envelope level value determines an amount of change to be applied to the original Tone level setting.

Applying Vibrato or Tremolo (LFO)

The LFO (Low Frequency Oscillator) can alter various Tone settings in a back-and-forth, cyclic manner. Each Tone has two LFOs, and each can apply the desired amount of repetitive change to the Tone’s Pitch, TVF cutoff frequency, TVA Level and TVA Pan settings. This can be used as the Matrix Control source (p. 100, p. 140).

How to Use the LFO

Applying an LFO to the Tone’s Pitch settings creates vibrato, applying it to its TVF cutoff frequency creates a wah-wah, and applying it to its TVA Level creates tremolo. When an LFO is applied to the Tone’s TVA Pan, the sound moves back and forth, from one side to another, in the stereo field. Depending on your settings, an LFO can also be used to cyclically exchange two Tones. For example, if you wish to shift back and forth between Tones 1 and 2, select the same LFO settings for both, but set their LFO TVA Depth settings to opposite polarities – set one to a + value, and the other to a - value.

LFO1(LFO2) WAVE

Since both LFOs have the same parameters, the following explanations applies to both.

Form (LFO form)

This selects the waveform the LFO is to use.

Offset (LFO offset)

This adjusts the basic width of the LFO waveform. SIN:sine wave

TRI:triangle wave

SAW-UP:sawtooth wave

SAW-DW:sawtooth wave (negative polarity)

SQR:square wave

RND:random wave

UP:Once the attack of the waveform output by the LFO is allowed to develop in standard fashion, the waveform then continues without further change.

DW:Once the decay of the waveform output by the LFO is allowed to develop in standard fashion, the waveform then

continues without further change. TRP:trapezoidal wave

S&H:sample & hold wave (LFO value is changed one time per cycle)

CHS:chaos wave

*When setting “UP” or “DW,” set the Key Sync parameter to “ON.” If this is “OFF,” it will have no effect.

Rate (LFO rate) 0–127/note

This adjusts the basic modulation rate, or speed, of the LFO.

*The Chaos waveform has no wavelength. When the Chaos waveform is selected, the Rate setting has no effect.

*For more information on the types of notes, refer to the Parameter List. (p. 151)

Detune (LFO rate detune) 0–127

This setting allows you to adjust the tuning of the LFO waveform.[RB2]

Key Sync (LFO key sync) OFF/ON

This sets whether you want the LFO cycle to start in sync with the timing of a key press (ON) or not (OFF).

LFO1(LFO2) FADE (LFO fade)

Fade Mode (LFO fade mode)

This sets how the LFO will be applied.

XV-3080 specifications

The Roland XV-3080 is a powerful and versatile sound module that has become a favorite among musicians, producers, and composers since its release in the late 1990s. This module is renowned for its extensive sound library, advanced synthesis capabilities, and user-friendly interface, making it a staple in studios and on stages worldwide.

One of the standout features of the XV-3080 is its impressive range of sounds. It boasts 1,024 preset sounds and 256 user patches, which can be expanded with Roland's SR-JV80 expansion boards to access even more diverse sounds. The XV-3080 is equipped with a Waveform Memory of 128 MB, providing high-quality samples and ensuring rich, detailed sound. The module also features a powerful multitimbral engine, allowing up to 16 simultaneous parts to be played, making it an ideal choice for complex arrangements and live performances.

Another key technology in the XV-3080 is its advanced SuperNATURAL technology. This innovation enhances traditional sample playback by incorporating physical modeling, enabling more expressive and nuanced tones. Musicians can take advantage of features like dynamic layering and velocity-sensitive control, adding an organic quality that is often missing in digital instruments.

The built-in effects processor is another highlight, offering a wide range of high-quality effects, including reverb, chorus, flanger, and distortion. These effects can be applied to individual parts or used globally, allowing for creative sound design and customization. The XV-3080 also supports real-time editing, letting users tweak parameters on the fly, which is particularly useful in live settings.

Connectivity is plentiful on the XV-3080, with MIDI In/Out, as well as digital and analog outputs. This allows for seamless integration with other equipment, whether it's a DAW, a keyboard controller, or an audio interface.

The XV-3080's intuitive interface, featuring a bright LCD screen and a straightforward layout, makes navigating through options quick and easy. Musicians can spend less time fumbling with settings and more time focusing on their music.

In summary, the Roland XV-3080 is a sophisticated sound module that combines cutting-edge technology with user-friendly features. Its extensive sound library, advanced synthesis capabilities, and solid effects processing make it an essential tool for any serious musician or producer looking to create professional-quality music.
