enumerateDevices :: IO [MIDIDeviceRef] Source
Note: If a client iterates through the devices and entities in the system, it will not ever visit any virtual sources and destinations created by other clients. Also, a device iteration will return devices which are offline (were present in the past but are not currently present), while iterations through the system's sources and destinations will not include the endpoints of offline devices.
Thus clients should usually use enumerateSources and enumerateDestinations, rather iterating through devices and entities to locate endpoints.
enumerateSources :: IO [Source] Source
Enumaretes the MIDI sources present.
enumerateDestinations :: IO [Destination] Source
Enumaretes the MIDI destinations present.
class MIDIObject a => MIDIHasName a where Source
MIDI objects which can have a name, model name and manufacturer
