Hello together, I use the AUX part from the second circuit (yellow piezo) to use a trigger bass drum pad on an drum modul which normally have only a switch pedal for the bass drum. The circuit works very well, but if I make smooth kicks the sensivity is a bit to low and some kicks don´t give a sound. How can I increase the sensitivity of these circuit? I tried to use a potentiometer for R1 to adjust the resistance, but it doenst help. How can I improve?
To get more sensitivity must I decrease R1 and increase R2?
Thank you for your help.
