Detailed Description

Subscriptions are virtual MIDI cables between readable and writable ports.

The ALSA sequencer readable ports are equivalent to the MIDI OUT ports in the real world. Similarly, the writable ports are equivalent to the MIDI IN ones. Subscriptions, like real MIDI cables, always involve a readable port (source) and a writable port (destination).

Classes:

Subscriber: This class is used to enumerate the subscribers of a given (root) port.

Subscription: This class represents a connection between two ports.
