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 111 of file alsaout.cc. References AlsaOut(). Referenced by AlsaOut(). |
|
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 126 of file alsaout.cc. References closeDev(). |
Member Function Documentation
|
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 from MidiOut. Definition at line 132 of file alsaout.cc. References openDev(). Referenced by openDev(). |
|
Closes the device. It basically tells the device (the file descriptor) is going to be closed.
Reimplemented from MidiOut. Definition at line 181 of file alsaout.cc. References ok(). Referenced by ~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.

Returns the name and type of this MIDI device.

Mutes all notes being played on a given channel.

|
Mute or "unmute" a given channel .
Reimplemented from MidiOut. Definition at line 438 of file alsaout.cc. References channelMute(), and channelSilence(). Referenced by channelMute(). |
|
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.
Reimplemented from MidiOut. Definition at line 203 of file alsaout.h. References setVolumePercentage(). Referenced by setVolumePercentage(). |
|
Returns true if everything's ok and false if there has been any problem.
Reimplemented from MidiOut. Definition at line 209 of file alsaout.h. Referenced by closeDev(), and initDev(). |
|
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.
