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
