+ The supported event types of an event port.

+ This is a kludge around Jack only supporting MIDI, particularly for OSC.
+ This property is a comma-separated list of event types, currently "MIDI" or
+ "OSC". If this contains "OSC", the port may carry OSC bundles (first byte
+ '#') or OSC messages (first byte '/'). Note that the "status byte" of both
+ OSC events is not a valid MIDI status byte, so MIDI clients that check the
+ status byte will gracefully ignore OSC messages if the user makes an
+ inappropriate connection.

+ their output directly to speakers. In particular, CV ports are not
+ necessarily periodic at all and may have very high DC.
