LFTri

A triangle oscillator UGen designed for low frequency control signals (being non-band-limited). The output varies from -1 to 1.

With an initial phase of zero, the oscillator begins at 0, rises to 1, then falls to -1 and goes back to zero after one complete phase. With an initial phase of 1 (corresponding to 90 degrees), the oscillator begins at 1 and then falls to -1. With an initial phase of 3 (or 270 degrees), the oscillator begins at -1 and then rises to 1.

Examples

// modulating frequency
play { LFTri.ar(XLine.kr(100, 20000, 10)) * 0.1 }

// modulating amplitude
play { LFTri.kr(XLine.kr(1, 200, 10)) * SinOsc.ar(440) * 0.1 }

// used as both oscillator and LFO
play { LFTri.ar(LFTri.kr(LFTri.kr(0.2).madd(8,10)).madd(400,800)) * 0.1 }
