## v Statement

v — Provides for locally variable time warping of score events.

## Description

The v statement provides for locally variable time warping of score events.

## Syntax

    v p1

## Initialization

p1 -- Time warp factor (must be positive).

## Performance

The v statement takes effect with the following i statement, and remains in effect until the next v statement, s statement, or e statement.

## Examples

The value of p1 is used as a multiplier for the start times (p2) of subsequent i statements.

    i1   0 1  ; note1
    v2
    i1   1 1  ; note2

In this example, the second note occurs two beats after the first note, and is twice as long.

Although the v statement is similar to the t statement, the v statement is local in operation. That is, v affects only the following notes, and its effect may be cancelled or changed by another v statement.

Carried values are unaffected by the v statement (see Carry).

    i1   0 1
    v2
    i.   + .
    i.   . .

In this example, the v statement has no effect.

## Examples

Here is an example of the v statement. It uses the file v.csd.

Example 1179. Example of the v statement.

    ;because note 3 and 5 are played simultaneously and are nearly of the same frequency,
    ;played together they will create a "beating" sound.

    </CsoundSynthesizer>

In this example, note3 and note5 occur simultaneously, while note4 actually occurs before note3, that is, at its original place. Durations are unaffected.
