LFTri

Triangle oscillator
Inherits from: LFSaw : PureUGen : UGen : AbstractFunction : Object

Description

A non-band-limited triangle oscillator. Output ranges from -1 to +1.

Class Methods

*ar (freq: 440, iphase: 0, mul: 1, add: 0)

From superclass: LFSaw

*kr (freq: 440, iphase: 0, mul: 1, add: 0)

From superclass: LFSaw

Arguments:

freq

Frequency in Hertz.

iphase

Initial phase offset. For efficiency reasons this is a value ranging from 0 to 4.

mul

Output will be multiplied by this value.

add

This value will be added to the output.

Examples

// plot:
{ LFTri.ar(40) }.plot(0.1);
{ LFTri.ar(XLine.kr(1, 800, 0.1)) }.plot(0.1);

{ LFTri.ar(500, 0, 0.1) }.play

// used as both Oscillator and LFO:
{ LFTri.ar(LFTri.kr(4, 0, 200, 400), 0, 0.1) }.play

// phase. compare
{ LFTri.ar(LFTri.kr(0.1, iphase: 0) * 200 + 400, 0, 0.1) }.play
{ LFTri.ar(LFTri.kr(0.1, iphase: 1) * 200 + 400, 0, 0.1) }.play
{ LFTri.ar(LFTri.kr(0.1, iphase: 2) * 200 + 400, 0, 0.1) }.play
{ LFTri.ar(LFTri.kr(0.1, iphase: 3) * 200 + 400, 0, 0.1) }.play

// together
{ LFTri.ar(LFTri.kr(0.05, iphase: (0..3)) * 200 + 400, 0, 0.1).sum }.play
