+# This plugin has three ports. There is an audio input and output as before,
+# as well as a new AtomPort. An AtomPort buffer contains an Atom, which is a
+# generic container for any type of data. In this case, we want to receive
+# MIDI events, so the (mandatory) +atom:bufferType+ is atom:Sequence, which is
+# a series of events with time stamps.
+#
+# Events themselves are also generic and can contain any type of data, but in
+# this case we are only interested in MIDI events. The (optional)
+# +atom:supports+ property describes which event types are supported. Though
+# not required, this information should always be given so the host knows what
+# types of event it can expect the plugin to understand.
+#
+# The (optional) +lv2:designation+ of this port is +lv2:control+, which
+# indicates that this is the "main" control port where the host should send
+# events it expects to configure the plugin, in this case changing the MIDI
+# program. This is necessary since it is possible to have several MIDI input
+# ports, though typically it is best to have one.
