Hello Danushka,

You would need to create a control from the transfer function. Then on the front panel, just expand the denominator column to get zero and first order for the denominator as shown here. Let me know if this helps.

Hello Danushka,

I think what you want is to use CD Construct Special TF Model VI as shown below
