Hi, can anyone share an example of setting biquad coefficients via a c# script?

double x

x=1.000

sigmastudio.ObjectSetProperties("setControlValue","R2", 0, 0, "B0", x);

does not throw an error, but has no effect. In this case, my filter is called "R2." I suspect the problem has to do with the type of the parameter, and have tried a few things to no avail. Can't find in docs anywhere.

Win 10 x64, SS 4.1, for an ADAU1772

Thanks,

Jeff

Found it! The biquad coefficients are called "Coefficients.B0" etc. So

ss.ObjectSetProperties( "setControlValue", "TestFilter", 0, 0, "Coefficients.B0" , 1.0 );
