filtergraph~ band control problem

Francesco Pasquale's icon

Hi guys. I am working on randomly automating the frequency and amplitude of a bell filter created with cascade~. However, I have noticed that the process is also affecting other filter points in filtergraph~.

How can I ensure that only the peak/notch filter is modulated?

Thank you very much for your help!

to display multiple filters (and only modulate one) you always need to send the whole bunch of coefficents again to filtergraph~:

[pak cascade 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]
