noteUp {ProTrackR}

Raise or lower notes and octaves

Description

Methods to raise or lower notes in PTCell, PTTrack and PTPattern objects.

Usage

## S4 method for signature 'PTCell'
noteUp(x, sample.nr = "all")

## S4 method for signature 'PTCell'
noteDown(x, sample.nr = "all")

## S4 method for signature 'PTCell'
octaveUp(x, sample.nr = "all")

## S4 method for signature 'PTCell'
octaveDown(x, sample.nr = "all")

## S4 method for signature 'PTTrack'
noteUp(x, sample.nr = "all")

## S4 method for signature 'PTTrack'
noteDown(x, sample.nr = "all")

## S4 method for signature 'PTTrack'
octaveUp(x, sample.nr = "all")

## S4 method for signature 'PTTrack'
octaveDown(x, sample.nr = "all")

## S4 method for signature 'PTPattern'
noteUp(x, sample.nr = "all")

## S4 method for signature 'PTPattern'
noteDown(x, sample.nr = "all")

## S4 method for signature 'PTPattern'
octaveUp(x, sample.nr = "all")

## S4 method for signature 'PTPattern'
octaveDown(x, sample.nr = "all")

Arguments

x

A PTCell, PTTrack or PTPattern object for which the notes need to be lowered or raised.

sample.nr

A single positive integer value, or a vector of positive integers, listing the indices of samples, for which the notes need to be lowered or raised. A character string equal to ⁠"all⁠" is also allowed (this is in fact the default), in which case notes of all sample indices are raised or lowered.

Value

Returns an object of the same class as object x, in which the notes for samples selected with sample.nr are raised or lowered.

In case raised or lowered notes would lead to notes that are out of ProTracker's range, the returned notes remain unchanged.
