/*! \page rawmidi RawMidi interface
\section rawmidi_ump UMP RawMidi Interface
MIDI 2.0 devices have a different type of interface, communicating with
UMP (Universal MIDI Packet). For those devices, ALSA-library provides
API functions for accessing the raw UMP packet directly via the existing
RawMidi interface.
#snd_ump_open() is the API function for opening a UMP RawMidi interface.
It works just like #snd_rawmidi_open() but for UMP devices. Similarly,
#snd_ump_close() is for closing, and there are other equivalent API functions
corresponding to the RawMidi ones.
The new stuff for UMP is UMP Endpoint and UMP Function Blocks. The information
from Endpoint and Function Blocks can be obtained via #snd_ump_endpoint_info()
and #snd_ump_block_info() API functions.
The objects #snd_ump_endpoint_info_t and #snd_ump_block_info_t are used for
creating a virtual UMP Endpoint and Function Blocks via ALSA sequencer, too.
