Parameters To setValueControl

Hello Christopher,

Would you please tell me which IC you are using in the project? If you would like to move this to a private conversation, let me know.

Thanks,

Brett

Hi Christopher,

First be aware that you can only set an "active" properites of a GUI control, where the 'setControlValue' is a GUI control. In this example, set the filter to "IIR Coefficient" in the filter type drop down menu which makes the "coefficient" controls active.

Otherwise the script will be ignored. The script will succeed which just means it compiled and ran successfully, there is no result returned by the actual filter object to signal script success or failure

The filter coefficients are in an object named "Coefficients", you can modify them via script as follows:

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

ss.ObjectSetProperties( "setControlValue", "TestFilter", 0, 0, "Coefficients.B1" , 2.0 );

etc..

Or you can set them all in a single command:

ss.ObjectSetProperties( "setControlValue", "TestFilter", 0, 0, "Coefficients" , new float[]{1.0f,2.0f,3.0f,4.0f,5.0f} );

The coefficient ordering is DSP dependent but for most ICs it is {A1, A2, B0, B1, B2}.

I realize this is neither intuitive or included in the documentation...but hope that helps :-0

Regards,

John

Since the "Control Value Name" are not published in detail, you might wonder how to find them? So here is a somewhat tedious method:

1. Insert the "Control UI" block located in the Processor IC section of the Hardware configuration toolbox.

Basic usage details of this control are documented here

2. Open the Control UI interface, and insert a knob or slider.

3. The "assign Parameter Control" window will open, and here you will see a list of the exposed "Control Value Name" for every GUI block in the project. These are the names that must be used in the "setControlValue" script command.

Thank you both for the replys.

@jmccarty The Coefficients.X worked! Thank you! I will also keep that tip in mind. :-D
