Total number of devices.

Total number of midi ports

A "constant" used to convert from milliseconds to the computer rate

Constructor. After constructing a MidiOut device, you must open it (using openDev() ). Additionally you may want to initialize it (with initDev() ),

[virtual]

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.

[virtual]

Opens the device. This is generally called from DeviceManager , so you shouldn't call this yourself (except if you created the MidiOut object yourself.

Parameters:

sqfd	a file descriptor of /dev/sequencer

See also: closeDev, initDev

Reimplemented from MidiOut

[virtual]

Closes the device. It basically tells the device (the file descriptor) is going to be closed.

Reimplemented from MidiOut

[virtual]

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 from MidiOut

[const]

• KMID_EXTERNAL_MIDI if it's a MidiOut object
• KMID_SYNTH if it's a SynthOut object (as an AWE device)
• KMID_FM if it's a FMOut object
• KMID_GUS if it's a GUSOut object

which are defined in midispec.h

Returns: the device type of the object. This is to identify the inherited class that a given object is polymorphed to. The returned value is one of these :

Reimplemented from MidiOut

[const virtual]

Returns the name and type of this MIDI device.

Mutes all notes being played on a given channel.

Reimplemented from MidiOut

[virtual]

Mute or "unmute" a given channel .

Parameters:

chn	channel to work on
b	if true, the device will ignore subsequent notes played on the chn channel, and mute all notes being played on it. If b is false, the channel is back to work.

Reimplemented from MidiOut

[virtual]

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.

Parameters:

volper

is an integer value, where 0 is quiet, 100 is used to send an unmodified value, 200 play music twice louder than it should, etc.

Reimplemented from MidiOut

Returns true if everything's ok and false if there has been any problem

Reimplemented from MidiOut

[virtual]

If i==1 syncronizes by cleaning the buffer instead of sending it (in fact, this is what syncronizing really means :-) )
