It has the verb receive in its name, but it actually does a transmission of events. Note: The MIDIReceivedEventList() name is a little bit misleading. the second argument is the list of events to be transmitted.the first argument is the source which is transmitting MIDI events.This function distributes incoming MIDI events from a source to its connected client input ports. We send the MIDI message to all the destinations connected using the MIDIReceivedEventList() CoreMIDI function. The 0x2, signify the Message Type being MIDI 1.0 Voice Channel Message. on line 8, we specify the command to be either Note On ( 0x20900000) or Note Off ( 0x20800000).

on line 6, we specify that the packet will have only one word of data.The lines above implement the Universal MIDI Packet encoding for sending MIDI 1.0 Voice Channel Messages. This function is named AskUserWhichNoteOn() and it is implemented as follows:

We develop a custom function that asks the user to key in the MIDI code of a note. We are ready to start emitting MIDI events with the notes that the user types in. Step 4: Repeat Asking User for a Note and Sending Out a MIDI event. It will discover the My Primitive MIDI Controller and will be able to connect to it. This is the time to start the application of the previous blog post. Important: from this point forward the application can be discovered by other applications.

the third argument is the address of the local variable source that will hold the handle to the created MIDI source.

This name will be printed by the connecting destination application (the Connecting to a MIDI Controller application).

the second argument is the name this MIDI source is going to present itself to the rest of the world.

the first argument is the handle to the MIDI client, client.

The CoreMIDI API that does the job here is the MIDISourceCreateWithProtocol(). The program we develop relies on the CoreMIDI API. The source code of this application can be found here. We limit the messages to NOTE ON and NOTE OFF messages in order to keep things simple, but the general idea demonstrated and the API used could be useful to build a full-featured MIDI controller. Hence, we can consider it being a primitive MIDI controller. Now, we develop a command line application that sends MIDI messages, like a MIDI Controller does. In the previous blog post, Connecting to a MIDI Controller, we developed a command line application that received MIDI messages from a MIDI Controller such as the Virtual MIDI Piano Keyboard (VMPK).
