I have tried to make make a controller box for the Bafo Soul Drum so it can be used with a PS2 for Drummania. It should have been fairly straight forward, but I think the variable output of the piezo triggers is giving me some problems. I can get the pads to trigger occasionally, but I have to hit the pads with a very specific amount of force.
What I need help with is on how to build a circuit that will limit the voltage to what the PS2 pad is looking for. Thanks in advance.
