Sample and hold
Source: Trig.sc
Subclasses: Gate

Description

Holds input signal value when triggered. Latch will output 0 until it receives its first trigger.

Class Methods

Latch.ar(in: 0, trig: 0)

Latch.kr(in: 0, trig: 0)

Arguments:

in

The input signal.

trig

Trigger. Trigger can be any signal. A trigger happens when the signal changes from non-positive to positive.

Examples

{ Blip.ar(Latch.ar(WhiteNoise.ar, Impulse.ar(9)) * 400 + 500, 4, 0.2) }.play;

The above is just meant as example. LFNoise0 is a faster way to generate random steps:

{ Blip.ar(LFNoise0.kr(9, 400 ,500), 4, 0.2) }.play;
