I have an electronic drumkit (Roland TD-8), and am wanting to trigger one of the inputs using a simple push to make switch.
The pads themselves work using piezo transducers. I believe by hitting the pads, the vibrations are picked up by the piezo which then generates a small voltage, which the drum kit module picks up on. Depending on how hard the pad is hit, the higher the voltage generated by the piezo, and the louder the sample played.
So - how could I go about triggering the module using a switch instead of the piezo? I'd like it to work such that when you press the switch, a small voltage is generated, but only for only brief moment.
Like this :
My basis knowledge leads me to something like this :
The LED would be replaced by 2 leads feeding into the drum module. This isn't what I want though, as I need it to be a push to make switch (so that it can be triggered very quickly, with minimal effort, using something like a small tactile switch). So I'm guessing the circuit could be redesigned using transistors to do what I want?
I'm hoping to learn all this stuff but for the time being, was wondering if someone could mock up a circuit that does what I'm after?
The other thing I'm not sure about is the amount of Voltage that should be produced.
