envelope depth when you play softly or hard. Negative (-) settings reverse the direction of change.

V-Curve (TVF envelope velocity curve)FIXED/1– 7

This selects one of seven velocity curves that determine how velocity will affect the depth of the TVF Envelope. The selected curve is displayed graphically to the right of its value.When set to “FIXED,” the TVF envelope depth remains unchanged, regardless of how hard or soft you play.

Time KF (TVF envelope time keyfollow)-100– +100

Use this parameter when you want a note’s keyboard position to affect times T2–T4 of the TVF envelope. Higher settings change the times by a greater amount as you move away from Middle C (C4) – at Middle C, the original T1–T4 settings are in effect. Positive (+) settings cause the times to shorten as you play above Middle C. Negative (-) settings cause the times to lengthen as you play above Middle C.

VT-1 (TVF envelope time 1 velocity sensitivity)- 63–+63

Use this parameter when you want keyboard playing dynamics (velocity) to affect T1 (Time 1) of the TVF envelope. With higher settings, the T1 value will change more significantly depending on whether you play softly or with greater force. With positive (+) settings, greater keyboard velocity will reduce the T1 setting. With negative (-) settings, greater keyboard velocity will increase the T1 setting.

VT-4 (TVF envelope time 4 velocity sensitivity)- 63–+63

Use this parameter when you want keyboard playing dynamics (velocity) to affect T4 (Time 4) of the TVF envelope. With higher settings, the T1 value will change more significantly depending on whether you play softly or with greater force. With positive (+) settings, greater keyboard velocity will reduce the T4 setting. With negative (-) settings, greater keyboard velocity will increase the T4 setting.

Chapter 4 Creating a Patch

T1–T4 (TVF envelope time 1–4)0–127

These settings determine the times over which the cutoff frequency setting will change from one TVF envelope level (L1–L4) to the next.

L1–L4 (TVF envelope level 1–4)0–127

Each TVF envelope level value determines an amount of change to be applied to the original cutoff frequency setting.

Making the Volume Change (TVA)

The TVA (Time Variant Amplifier) controls volume changes to the Tone as well as its stereo positioning.

TVA

Level (Tone level)0–127

This sets the Tone’s basic volume. This setting is useful primarily for adjusting the volume balance between Tones in

aPatch.

*The overall volume of the Patch is set by the Patch Level (PATCH LVL&PAN page) setting, raising or lowering the Tone level settings of its individual Tones by the selected amount. (p. 85)

Pan (Tone Pan)L64–0–63R

This specifies the stereo position of the Tone. L64 places the Tone hard left, 0 puts it dead-center and 63R pans it hard right.

*The overall panning of the entire Patch is set by the Patch Pan parameter (PATCH LVL&PAN page), shifting the Tone Pan values of its individual Tones leftward or rightward by the selected amount. (p. 85)

V-Sens (TVA level velocity sensitivity)-63–+63

Use this setting when you want keyboard touch (velocity) to affect the Tone volume. Set this to a positive value to have the changes in tone volume increase the more forcefully the keys are played; to make the Tone play more softly as you play harder, set this to a negative value.

V-Curve (TVA level velocity curve)FIXED/1–7

This setting allows you to select from seven velocity curves that determine how the force with which the keyboard is played is to affect the Tone’s volume. The selected curve is displayed to the right of its parameter value.

When set to “FIXED,” the Tone’s volume will not be affected by the force with which the keyboard is played.

L0 (TVF envelope level 0)0–127

**** chaaaange This sets the amount of change applied to the cutoff frequency setting when the key is first pressed.

BIAS

Use the Bias parameter when you want the position of notes on a keyboard to affect the TVA level.

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.
