related:: Classes/LeastChange, Classes/MostChange
categories:: UGens>Triggers
Description::
Output the last value before the input changed more than a threshold.
classmethods::
method::ar, kr
argument::in
The input signal.
argument::diff
Difference threshold.
Examples::
code::
d = { arg freq=440; SinOsc.ar(LastValue.ar(freq, 20), 0, 0.2) }.play;
d.set(\freq, 400);
d.set(\freq, 200);
d.set(\freq, 670);
d.set(\freq, 680);
d.set(\freq, 695);
d.free;
::
Return the difference between current and the last changed:
code::
(
d = { arg out=0, val=1;
SinOsc.ar(
abs(val - LastValue.kr(val)) * 400 + 200,
0, 0.2
)
}.play;
)
d.set(\val, 3);
d.set(\val, 2);
d.set(\val, 0.2);
d.set(\val, 1);
d.set(\val, 2);
d.free;
