Hi!
I'm starting to learn Pd Extended and I trying to make a filter able to highpass, lowpass, both things or neither of them, but I'm having problems making a toggle to bypass the filters:
While in the highpass filter everything works fine (I can move the slider to the frequency I want, I can turn it off and I can turn it on again keeping the frequency I chose before), when I try to do the same on the lowpass filter, everytime I turn the toggle off (as a bypass), I stop hearing the sound.
Here is my configuration and my patch:

Thank you in advice!
