Syntax

connectionInfo = getMIDIConnections(audioObject)

Description

connectionInfo = getMIDIConnections(audioObject) returns a structure, connectionInfo, containing information about the MIDI connections for your audio object, audioObject. Only those MIDI connections established using configureMIDI are returned.

The connectionInfo structure contains a substructure for each tunable property of audioObject that has established MIDI connections. Each substructure contains the control number, the device name of the corresponding MIDI control, and the property mapping information (mapping rule, minimum value, and maximum value).

Examples

Create an object of the audio plugin example audiopluginexample.Echo.

echoEffect = audiopluginexample.Echo;

Use configureMIDI to synchronize echoEffect properties with specific MIDI controls on the default MIDI device.

configureMIDI(echoEffect,'Delay1',1001);
configureMIDI(echoEffect,'Gain1' ,1002);
configureMIDI(echoEffect,'Delay2',1003);
configureMIDI(echoEffect,'Gain2' ,1004);

Use getMIDIConnections to view the MIDI connections you established.

connectionInfo = getMIDIConnections(echoEffect)
connectionInfo = 

    Delay1: [1x1 struct]
     Gain1: [1x1 struct]
    Delay2: [1x1 struct]
     Gain2: [1x1 struct]

View details of the Delay1 MIDI connection using dot notation.

connectionInfo.Delay1
ans = 

            Law: 'lin'
            Min: 0
            Max: 1
    MIDIControl: 'control 1001 on 'nanoKONTROL2''

Information about MIDI connection between the specified audio plugin object and MIDI devices, returned as a structure. Only those MIDI connections established using configureMIDI are returned. The connectionInfo structure contains a substructure for each established MIDI connection. Each substructure contains the control number, the device name of the corresponding MIDI control, and the property mapping information (mapping rule, minimum value, and maximum value).
