Settings View Source Midiex.MidiMessage (Midiex v0.6.1)

A struct representing MIDI messages recieved from MIDI inputs.

These are recieved via the Midiex.subscribe() function or from the Midiex.Listener GenServer.

The keys are as follows:

• port: which is the input port (%Midiex.MidiPort{}) that sent the message
• data: the MIDI message data, usually in the form of a three item list, e.g. [153, 60, 70]
• timestamp: from the midir docs: "a timestamp (in microseconds) designating the time since some unspecified point in the past (which will not change during the lifetime of an input connection)".
