Ok, I need a piezo element to drive a comparator to close a solid- state switch. All this to interface to a Alesis Hr-16 Drum Machine that uses a piezo element and a switch to drive itself. Can someone provide me with a circuit diagram? I'm not an electrician, I'm a musician, but I like to put things together and save money. The comparator will close a switch run in parallel with the original HR-16 switch, and the raw piezo signal will also be hooked up in parallel with the hr-16 piezos. Does any one see a need for a buffer op-amp on the piezo output? Thanks alot! Ken Morton v097pba8@ubvms.Bitnet v097pba8@ubvmsd.cc.buffalo.edu
