This is an inexpensive midi in/audio out chip from Atmel, it's the ATSAM2195 bought on www.ARROW.com (the only place that sells it individually) mounted on a QFN44 to DIP48 adapter (#4609 from www.PROTO-ADVANTAGE.com they soldered it for me). I'm sending midi signal from my ARDUINO compatible BOARDUINO to a hex inverter chip (not necessary, it can be left out), then the midi signal is going to the computer through my USB / MIDI adapter (also dirt cheap on ebay, I stripped it but it looks nicer in its shell) and also the midi signal is going to the ATSAM2195-EK evaluation board circuit (you don't have to use tantalum or any fancy EMI filters) then the audio from the board is going to my stripped down amplifier then from it to the speaker. On the video you can see me turning off the "Bome's Mouse Keyboard" freeware (great thing cause it's free) and all you hear is the great sound of the DREAM team ATSAM2195 chip.
Very cool!
