Detailed Description

Represents a midi input device.

To create one of these, use the static getAvailableDevices() method to find out what inputs are available, and then use the openDevice() method to try to open one.

Member Function Documentation

getAvailableDevices()

static Array<MidiDeviceInfo> MidiInput::getAvailableDevices ( )

static

Returns a list of the available midi input devices.

You can open one of the devices by passing its identifier into the openDevice() method.

See also

MidiDeviceInfo, getDevices, getDefaultDeviceIndex, openDevice

getDefaultDevice()

static MidiDeviceInfo MidiInput::getDefaultDevice ( )

static

Returns the MidiDeviceInfo of the default midi input device to use.

openDevice() [1/2]

static std::unique_ptr<MidiInput> MidiInput::openDevice ( const String &  deviceIdentifier, MidiInputCallback *  callback  )

static

Tries to open one of the midi input devices.

This will return a MidiInput object if it manages to open it, you can then call start() and stop() on this device.

If the device can't be opened, this will return an empty object.

Parameters

deviceIdentifier	the ID of the device to open - use the getAvailableDevices() method to find the available devices that can be opened
callback	the object that will receive the midi messages from this device

See also

MidiInputCallback, getDevices

createNewDevice()

static std::unique_ptr<MidiInput> MidiInput::createNewDevice ( const String &  deviceName, MidiInputCallback *  callback  )

static

This will try to create a new midi input device (only available on Linux, macOS and iOS).

This will attempt to create a new midi input device with the specified name for other apps to connect to.

NB - if you are calling this method on iOS you must have enabled the "Audio Background Capability" setting in the iOS exporter otherwise this method will fail.

Returns an empty object if a device can't be created.

Parameters

deviceName	the name of the device to create
callback	the object that will receive the midi messages from this device

start()

void MidiInput::start

(

)

Starts the device running.

After calling this, the device will start sending midi messages to the MidiInputCallback object that was specified when the openDevice() method was called.

See also

stop

stop()

void MidiInput::stop

(

)

Stops the device running.

See also

start

getDeviceInfo()

MidiDeviceInfo MidiInput::getDeviceInfo ( ) const

noexcept

Returns the MidiDeviceInfo struct containing some information about this device.

getIdentifier()

String MidiInput::getIdentifier ( ) const

noexcept

Returns the identifier of this device.

getName()

String MidiInput::getName ( ) const

noexcept

Returns the name of this device.

setName()

void MidiInput::setName ( const String &  newName )

noexcept

Sets a custom name for the device.
