Description::
|
|
|
|
A non-band-limited triangle oscillator. Output ranges from -1 to +1.
|
|
|
|
|
|
classmethods::
|
|
|
|
method::ar, kr
|
|
|
|
argument::freq
|
|
Frequency in Hertz.
|
|
|
|
argument::iphase
|
|
|
|
Initial phase offset. For efficiency reasons this is a value
|
|
ranging from 0 to 4.
|
|
|
|
|
|
argument::mul
|
|
Output will be multiplied by this value.
|
|
|
|
argument::add
|
|
This value will be added to the output.
|
|
|
|
Examples::
|
|
|
|
code::
|
|
// 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
