pwm()

pwm(x, width)

Description

Pulse-width oscillator. The second argument controls the pulse width, normally from about 0.05 to 0.95; animated width values create classic PWM motion.

Waveform

Example: pwm(X,0.5)

Arguments

x: phase or signal input; for pitched oscillators use X for the played MIDI note
width: pulse width, normally 0.05 to 0.95

Typical Values

Width is most useful around 0.05 to 0.95. Avoid exactly 0.0 or 1.0 for sustained tones because very narrow pulses can become silent or clicky.

Example

pwm(X, 0.4)

Notes

For pitched oscillator functions, X already contains the current MIDI note pitch and transpose information. Prefer saw(X), sin(X), or pwm(X, 0.4) unless you intentionally want an octave or ratio shift such as 0.5*X or 2*X.
