VarSaw

A sawtooth-triangle oscillator UGen with variable duty. A width of zero produces a sawtooth of falling slope, with an initial phase of zero making it start at +1. A width of 0.5 produces a triangle wave, starting at -1 then raising to +1, then falling again to -1. A width of 1.0 produces a sawtooth of rising slope, starting -1.

Increasing the initial wave will increase the offset into the waveform. For example, with a phase of 0.5 and a width of 0.5, the result is a triangle waveform that starts at +1.

There is a strange anomaly for the falling sawtooth (zero width): Instead of starting directly at +1, the first sample is -1 and only from the second sample at +1 the waveform starts falling. In other words, the waveform has a delay of one sample.

Examples

// width modulation
play {
  val freq  = LFPulse.kr(3, 0, 0.3).madd(200, 200)
  val width = LFTri.kr(1.0).madd(0.5, 0.5)
  VarSaw.ar(freq, 0, width) * 0.2
}
