Description: The SparkFun MIDI Shield board gives your Arduino access to the antiquated, but still widely used and well supported MIDI communication protocol, so you can control synthesizers, sequencers, and other musical devices. The MIDI protocol shares many similarities with standard asynchronous serial interfaces, so you can use the UART pins of your Arduino to send and receive MIDI’s event messages.
The MIDI Shield provides an opto-isolated MIDI-IN port as well as a MIDI-OUT port. The MIDI Shield can be mounted directly on top of an Arduino, connecting the MIDI-IN to the Arduino’s hardware RX pin and the MIDI-OUT to TX. Potentiometers are connected to analog pins 1 and 2, and can be used to control volume, pitch, tone or anything else you’d like. Also connected on the shield are three momentary push buttons (connected to D2-4), a reset button, and green and red stat LEDs. The RUN/PROG switch allows you to program the Arduino over serial without having to remove the shield.
Note: The MIDI Shield does not come with the through-hole MIDI connectors or trimpots soldered on. All of these components (2 MIDI connectors and 2 trimpots) are included with the product, however
Note: When using this shield with the Arduino Pro you will have to bypass the TX/RX resistors on the Pro to get enough current to the shield.

Works just as described
I believe the onboard switch that changes modes from “Program” to “Run” is bad. The unit will only operate if pressure is exerted on the teenie switch. This is a component pre-installed, not a part that I had to solder to the board, or I would blame myself. But it appears to just be a “bad one.” Pretty disappointing as I had big plans for this unit and was going to get some more for other projects. I guess Ill keep searching for a better one.
