Custom Math with multiple inputs

Hello to Dewesoft Developing community.

I had one question on custom math plugin. How can I made a multiple input frame with drop down menu for a custom math plugin. A example idea like the strain Rosette input section.

Hi,

When registering plugin, this needs to be written into register:
Reg.WriteInteger('ModuleType', 1); //0-one channel input 1-many ch. input

On GetInputChannels the channel list of all the input channels needs to be filed:

procedure TMath.Math_GetInputChannels(List: TStringList);

begin
List.Add('Input A');
List.Add('Input B');
List.Add('Input C');
end;

Thanks for your answer.
