This library enables MIDI I/O communications on the Arduino serial ports.

The purpose of this library is not to make a big synthesizer out of an Arduino board, the application remains yours. However, it will help you interfacing it with other MIDI devices.

### What do I need to do?
43
-
44
-
* Download the library ([link](https://github.com/FortySevenEffects/arduino_midi_library/releases/latest)).
45
-
* Follow the installation instructions - http://arduino.cc/en/Guide/Libraries.
46
-
* Include the library in your sketch using the menu in the IDE, or type `#include <MIDI.h>`
47
-
* Create the MIDI instance using `MIDI_CREATE_DEFAULT_INSTANCE();` or take a look at the documentation for custom serial port, settings etc..

You are now ready to use the library. Look at the documentation to learn how to use it, or checkout the examples installed with the Library.
50

You can also watch the awesome video tutorials from [Notes & Volts](https://www.youtube.com/playlist?list=PL4_gPbvyebyH2xfPXePHtx8gK5zPBrVkg).

1. Use Arduino's Library Manager to install the library.
24
+
2. Start coding:
25
+
```c++
26
+
#include<MIDI.h>
52

##Documentation

// Created and binds the MIDI interface to the default hardware Serial port
29

MIDI_CREATE_DEFAULT_INSTANCE();

See the extended documentation [here](http://arduinomidilib.fortyseveneffects.com) ([Mirror](http://fortyseveneffects.github.io/arduino_midi_library/)).

voidsetup()
32
+
{
33
+
MIDI.begin(MIDI_CHANNEL_OMNI); // Listen to all incoming messages

}

### Using MIDI.begin
36
+
void loop()
37
+
{
38
+
// Send note 42 with velocity 127 on channel 1
39
+
MIDI.sendNoteOn(42, 127, 1);

In the `setup()` function of the Arduino, you must call the `MIDI.begin()` method. If you don't give any argument to this method, the input channel for MIDI in will be set to 1 (channels are going from 1 to 16, plus `MIDI_CHANNEL_OMNI to listen to all channels at the same time).
41
+
// Read incoming messages
42
+
MIDI.read();
43
+
}
44
+
```

This method will:
62
-
* Start the serial port at the MIDI baudrate (31250).
63
-
* Set the input channel at the argument given (if any, else 1).
64
-
* Enable Soft Thru, without filtering (everything at the input is sent back).

3. Read the [documentation](#documentation) or watch the awesome video tutorials from [Notes & Volts](https://www.youtube.com/playlist?list=PL4_gPbvyebyH2xfPXePHtx8gK5zPBrVkg).

### MIDI Thru
69
-
70
-
The MIDI Thru allows you to redirect your incoming messages to the MIDI output. It replaces the need of a MIDI Thru connector, as it copies every valid incoming message from the input. For good performance, you might want to call read() in a fast loop, for low latency.
71
-
72
-
Incoming unread bytes/messages are kept in the Arduino serial buffer, in order not to flood it, check regularily with MIDI.read. See the documentation for Thru explanations.
73
-
74
-
Thru is enabled by default, you can turn it off using appropriate methods.
