View Source Midiex.MidiPort (Midiex v0.5.0)
A struct representing a MIDI port.
The keys are as follows:
- direction which is an atom of value
:input
or:output
(for input or output port) - name which is a string the backend reported as the name of the port. With MIDI hardware, this is often the name of the device.
- num an integer index representing the port starting at 0. Both input and output ports will start with 0.
- port_ref a reference (e.g.
#Reference<0.2239960018.1937899544.176288>
) to the port object in midir (Rust).

Notes from midir
How a port is identified internally is backend-dependent. If the backend allows it, port objects remain valid when other ports in the system change (i.e. it is not just an index).

Example
Midiex.ports()
This will return MIDI ports available on your system, for example:
[
%Midiex.MidiPort{
direction: :input,
name: "IAC Driver Bus 1",
num: 0,
port_ref: #Reference<0.2239960018.1937899544.176288>
},
%Midiex.MidiPort{
direction: :output,
name: "IAC Driver Bus 1",
num: 0,
port_ref: #Reference<0.2239960018.1937899544.176289>
}
