MidiOut Class Reference
#include <midiout.h>
Inheritance diagram for MidiOut:

Detailed Description
External MIDI port output class .Sends MIDI events to external MIDI devices.This class is used to send midi events to external midi devices.
MidiOut is inherited by other MIDI devices classes (like SynthOut or FMOut) to support a common API.
In general, you don't want to use MidiOut directly, but within a DeviceManager object, which is the preferred way to generate music.
If you want to add support for other devices (I don't think there are any) you just have to create a class that inherits from MidiOut and create one object of your new class in DeviceManager::initManager().

Constructor & Destructor Documentation
|
Constructor. After constructing a MidiOut device, you must open it (using openDev() ). Additionally you may want to initialize it (with initDev() ), Definition at line 46 of file midiout.cc. |
|
Destructor. It doesn't matter if you close the device ( closeDev() ) before you destruct the object because in other case, it will be closed here. Definition at line 57 of file midiout.cc. |

Send a All Notes Off event to every channel.

|
Closes the device. It basically tells the device (the file descriptor) is going to be closed.
Reimplemented in AlsaOut, FMOut, GUSOut, and SynthOut. Definition at line 77 of file midiout.cc. |
|
Returns the name and type of this MIDI device.
Reimplemented in AlsaOut. Definition at line 280 of file midiout.cc. |
|
Reimplemented in AlsaOut. |
|
Initializes the device sending generic standard midi events and controllers, such as changing the patches of each channel to an Acoustic Piano (000), setting the volume to a normal value, etc.
Reimplemented in AlsaOut, FMOut, GUSOut, and SynthOut. Definition at line 86 of file midiout.cc. |
|
See DeviceManager::keyPressure().
Reimplemented in AlsaOut, FMOut, GUSOut, and SynthOut. Definition at line 140 of file midiout.cc. |
|
Returns the path to the file where the current used MidiMapper object reads the configuration from, or an empty string if there's no MidiMapper.

|
Returns true if everything's ok and false if there has been any problem.
Reimplemented in AlsaOut. |
|
Opens the device. This is generally called from DeviceManager , so you shouldn't call this yourself (except if you created the MidiOut object yourself.
Reimplemented in AlsaOut, FMOut, GUSOut, and SynthOut. Definition at line 63 of file midiout.cc. |
|
Sets a MidiMapper object to be used to modify the midi events before sending them.
Definition at line 107 of file midiout.cc. |
|
Change all channel volume events multiplying it by this percentage correction Instead of forcing a channel to a fixed volume, this method allows to music to fade out even when it was being played softly.
|
|
Sends the buffer to the device and returns when it's played, so you can synchronize XXX: sync should be virtual after next bic release.
Reimplemented in AlsaOut. Definition at line 294 of file midiout.cc. |
|
See DeviceManager::sysex().
