device` the device to use for sending 

* `song` the song to select

#### `public void `[`midi_send_tunerequest`](#group__send__functions_1ga8db6c7e04d48e4d2266dd59118ca0656)`(`[`MidiDevice`](#struct__midi__device)` * device)` {#group__send__functions_1ga8db6c7e04d48e4d2266dd59118ca0656}

Send a tune request message via the given device.

#### Parameters
* `device` the device to use for sending

#### `public void `[`midi_send_byte`](#group__send__functions_1ga857e85eb90b288385642d4d991e09881)`(`[`MidiDevice`](#struct__midi__device)` * device,uint8_t b)` {#group__send__functions_1ga857e85eb90b288385642d4d991e09881}

Send a byte via the given device.

This is a generic method for sending data via the given midi device. This would be useful for sending sysex data or messages that are not implemented in this API, if there are any. Please contact the author if you find some so we can add them.

#### Parameters
* `device` the device to use for sending 

* `b` the byte to send

#### `public void `[`midi_send_data`](#group__send__functions_1ga36e2f2e45369d911b76969361679054b)`(`[`MidiDevice`](#struct__midi__device)` * device,uint16_t count,uint8_t byte0,uint8_t byte1,uint8_t byte2)` {#group__send__functions_1ga36e2f2e45369d911b76969361679054b}

Send up to 3 bytes of data.

% 4 is applied to count so that you can use this to pass sysex through

#### Parameters
* `device` the device to use for sending 

* `count` the count of bytes to send, %4 is applied 

* `byte0` the first byte 

* `byte1` the second byte, ignored if cnt % 4 != 2 

* `byte2` the third byte, ignored if cnt % 4 != 3

#### `public void `[`midi_send_array`](#group__send__functions_1ga245243cb1da18d2cea18d4b18d846ead)`(`[`MidiDevice`](#struct__midi__device)` * device,uint16_t count,uint8_t * array)` {#group__send__functions_1ga245243cb1da18d2cea18d4b18d846ead}

Send an array of formatted midi data.

Can be used for sysex.

#### Parameters
* `device` the device to use for sending 

* `count` the count of bytes to send 

* `array` the array of bytes
