/*! \class RtMidi
|
|
\brief STK realtime MIDI class.
|
|
|
|
At the moment, this object only handles MIDI
|
|
input, though MIDI output code can go here
|
|
when someone decides they need it (and writes
|
|
it).
|
|
|
|
This object opens a MIDI input device and
|
|
parses MIDI messages into a MIDI buffer. Time
|
|
stamp info is converted to a delta-time
|
|
value. MIDI data is stored as MY_FLOAT to
|
|
conform with SKINI. System exclusive messages
|
|
are currently ignored.
|
|
|
|
An optional argument to the constructor can be
|
|
used to specify a device or card. When no
|
|
argument is given, a default device is opened.
|
|
If a device argument fails, a list of available
|
|
devices is printed to allow selection by the user.
|
|
|
|
This code is based in part on work of Perry
|
|
Cook (SGI), Paul Leonard (Linux), the
|
|
RoseGarden team (Linux), and Bill Putnam
|
|
(Windows).
|
|
|
