One of my first Arduino projects, is trying to build a drum trigger that can use piezo-elements as sensors and then convert the signal to MIDI messages in the MCU.

My first attempt kind'a worked, so I build this shield that fits nicely on top of the Arduino:

Here it is again using all the analog inputs on the Atmega, making it a 6-chanal midi-drum-trigger. I've also added a 2x16 LCD and some buttons to control the individual channels :

With the new Arduino DUE it is now possible to add several inputs without loosing precision. The current version have 12 inputs (last two jack's are for dual-triggers) and a blue 4x20 display.
