Hello Peter, thanks for the help. Unfortunately it doesn't work with the [vcf~]
object either. As you say, the problem is that I jump from a frequency to the
next non-continuosly. Is there a way to do that without interrupting the signal
and without noise?

Daniel, can you try the [vcf~] object instead of [bp~]? The noise you
hear most likely happens when you change the filter frequency
non-continuously.
