|
Description::
|
||
|
|
When triggered, Timer measures the time (in seconds) elapsed since the previous trigger, and outputs this time value as a constant. Its output will not change until the next trigger. The initial value is 0.
|
||
|
|
|
||
|
|
If you need the time since the last trigger, where the time is continually updated, see link::Classes/Sweep::.

|
|
A trigger occurs when trig signal crosses from non-positive to positive.

Examples::
|
||
|
|
|
||
|
|
code::
|
||
|
|
|
||
|
|
// using timer to modulate sine frequency: the slower the trigger is the higher the frequency
|
||
|
|
(
|
||
|
|
{ var trig;
|
||
|
|
trig = Impulse.kr(MouseX.kr(0.5, 20, 1));
|
||
|
|
SinOsc.ar(Timer.kr(trig) * 500 + 500, 0, 0.2)
|

}.play;
