trapezoid~

Trapezoid wavetable operator.

Description

trapezoid~ is a trapezoidal wavetable operator with a signal input. The ramp up and down position values are independently adjustable.

Arguments

rampUp [auto]

Optional

The rampUp argument sets the phase value (0.0 ... 1.0) where the trapezoid will hit its peak. A floating-point or signal value can be used to specify the ramp up value. The arguments 0. 0. produce a ramp waveform, and 0.5 0.5 produces a triangle waveform. Default: 0.5.

rampDown [auto]

Optional

The rampDown argument sets the phase value (0.0 ... 1.0) where the trapezoid will begin dropping back to the minimum. A floating-point value can be used to specify the ramp down value. The arguments 0. 0. produce a ramp waveform, and 0.5 0.5 produces a triangle waveform. Default: 0.5.

Inlets

phase [auto]

The input to trapezoid~ should be a that repeatedly goes from 0 to 1.

rampUp [auto]

The rampUp argument sets the phase value (0.0 ... 1.0) where the trapezoid will hit its peak. A floating-point or signal value can be used to specify the ramp up value. The arguments 0. 0. produce a ramp waveform, and 0.5 0.5 produces a triangle waveform. Default: 0.5.

rampDown [auto]

The rampDown argument sets the phase value (0.0 ... 1.0) where the trapezoid will begin dropping back to the minimum. A floating-point value can be used to specify the ramp down value. The arguments 0. 0. produce a ramp waveform, and 0.5 0.5 produces a triangle waveform. Default: 0.5.

Outlets

out1 [signal]

A signal which corresponds to the value referenced by the trapezoid~ operator's input signal. If the output of a phasor~ or some other audio signal is used to scan the trapezoid~ object, the output will be a periodic waveform.
