Takashi Iwai aa5e949403 aplaymidi2: Add initial version
aplaymidi2 is a program similar like aplaymidi, but intended for
playing back a MIDI Clip file that was introduced for handling UMP.
MIDI Clip file contains UMP packets, and its structure is much simpler
than SMF.

The options are mostly same as aplaymidi, but I omitted -l option for
simplifying the code.

.SH NAME
aplaymidi2 \- play MIDI Clip Files
.SH SYNOPSIS
.B aplaymidi2
\-p client:port[,...] midi2file ...
.SH DESCRIPTION
.B aplaymidi2
is a command-line utility that plays the specified MIDI Clip file(s) to one
or more ALSA sequencer ports.
.SH OPTIONS
.TP
.I \-h, \-\-help
Prints a list of options.
.TP
.I \-V, \-\-version
Prints the current version.
.TP
.I \-p, \-\-port=client:port,...
Sets the sequencer port(s) to which the events in the MIDI Clip file(s) are
sent.
A client can be specified by its number, its name, or a prefix of its
name. A port is specified by its number; for port 0 of a client, the
":0" part of the port specification can be omitted.
Multiple ports can be specified to allow playback of MIDI Clip file(s) that
contain events for multiple devices (ports) corresponding to the
multiple UMP Groups.
For compatibility with
.B pmidi(1),
the port specification is taken from the
.I ALSA_OUTPUT_PORTS
environment variable if none is given on the command line.
.B aplaymidi2
supports only basic UMP events: in addition to the standard MIDI1 and
MIDI2 CVMs and 7bit SysEx, only the following are supported:
DCTPQ, DC, Set Tempo, Start Clip and End Clip.
Lyrics and other meta data in Flex Data are skipped, so far.
The multiple output ports are useful when the given MIDI Clip file
contains the UMP packets for multiple Groups.
When the destination port is a UMP MIDI 2.0 port, the single
connection should suffice, though, since a MIDI 2.0 port can process
the inputs for multiple Groups. For other cases (e.g. connecting to a
legacy MIDI port), you would need to specify the destination port per
Group. If undefined, it's sent to the first destination port as
default.
.TP
.I \-d, \-\-delay=seconds
Specifies how long to wait after the end of each MIDI Clip file,
to allow the last notes to die away.
Default is 2 seconds.
