I'm a little new to Arduino but I was wondering if I wanted to build a electronic drum MIDI interface using the Arduino board is there any controller interface board where I could set up mu MIDI channels, note numbers, ETC. Something with a display just like a regular MIDI drum interface?
yes Todbot has an excellent tutorial on sensing piezo's and then sending that out as midi data. There are other midi tutorials/info pages as well. Look under the "midi" heading here.
