           Hello Lorenzo,
      

           My eval board has only one pot so i made an example volume control and a separate one-band EQ.  Please download and open them to observe how they're built.  You'll need to build up your circuit by cascading the volume control and three EQs, setting them to the desired frequencies.  Use one Aux ADC with one pot on your Wondom board to control each of these.  Set the HW Config / Register Settings to assign the MP pins for the Aux ADCs (I'm only using ADC3, which corresponds to MP8).
      

           Best regards,
      

           Bob
