Hi MP, Thanks for the State Variable filter tutorial. As an audio engineer, I encountered this design a lot of times, however mostly with different values of C1 and C2. Could you please explain me what's the effect of using different values for C1 and C2 and how it would be possible to determine the bandpass center frequency out of a given design with different values of C1 and C2? Many thanks in advance! PS I just got to know this forum; really inspiring! Greetz, Rogy
