y rotation linked 2 soundkeys output

Posted by Dzakwan Kurnia on September 14, 2018 at 7:12 am

Hi everyone, can you help me to fix my problem?

i want to connect null object y rotation with 2 output soundkeys

i have this for expression:
minAudio = 7;
maxAudio = 50;
minStretch = 0;
maxStretch = 50;

and this my soundkeys output
thisComp.layer(“a3”).effect(“Sound Keys”)(“Output 1”)
thisComp.layer(“a3”).effect(“Sound Keys 2”)(“Output 1”)

for sure..
example:
in this frame,
first output value 10, and second output value 0
and next frame, first output is value 0, and second output value 20

i want to make first output value (-) and make first output value plus second output value
or you can say, if y1= first output and y2 = second output, may be like this —> -y1 + y2 = value for expression

i already try this one
minAudio = 7;
maxAudio = 50;
minStretch = 0;
maxStretch = 50;

y=-(thisComp.layer(“a3”).effect(“Sound Keys”)(“Output 1”)*-1)+(thisComp.layer(“a3”).effect(“Sound Keys 2”)(“Output 1”))

yr = linear(y, minAudio, maxAudio, minStretch, maxStretch);
[yr]

and this one
minAudio = 7;
maxAudio = 50;
minStretch = 0;
maxStretch = 50;
y1=thisComp.layer(“a3”).effect(“Sound Keys”)(“Output 1”);
y2=thisComp.layer(“a3”).effect(“Sound Keys 2”)(“Output 1”);
y=(-y1)+y2;
yr = linear(y, minAudio, maxAudio, minStretch, maxStretch);
[yr]

all not working, or work but have a missing expression
plese some one help me, im sorry for my less experience, and thanks.

From a quick look, seems ok apart from the last line, take out the brackets around the “yr”.

fixed sir
I’m not thinking about this
make command to yr1 for y1 and yr2 for y2

minAudio = 7;
maxAudio = 50;
minStretch = 0;
maxStretch = 5;
y1=thisComp.layer(“a3”).effect(“Sound Keys”)(“Output 1”);
y2=thisComp.layer(“a3”).effect(“Sound Keys 2”)(“Output 1”);
yr1 = linear (y1, minAudio, maxAudio, minStretch, maxStretch);
yr2 = linear (y2, minAudio, maxAudio, minStretch, maxStretch);
[(-yr1)+yr2]

im sorry for wasting your time, and im verry thanks sir.
