MIDI Device Manager class .Manages all MIDI devices and redirects MIDI events to each one as configured.
<p>
This class is the one you should use to send MIDI events to any device, as it creates and manages the *Out classes.<p>
This class is usually used by creating a DeviceManager object, then call <a class="el" href="classDeviceManager.html#a10">openDev()</a> and <a class="el" href="classDeviceManager.html#a12">initDev()</a> . Then, use numberOfMidiPorts(), numberOfSynthDevices(), <a class="el" href="classDeviceManager.html#a37">name()</a> and <a class="el" href="classDeviceManager.html#a38">type()</a> to choose which device to play MIDI events to and then use <a class="el" href="classDeviceManager.html#a29">defaultDevice()</a> to set the MIDI device to play.<p>

Sends a Controller event to a MIDI channel.
<p>
This can be used for example to change the volume, set a XG patch, etc. Look for any General Midi resource page on the net for more information about the available controller events.<p>
For example, to set the tremolo value to a maximum on the MIDI channel number one, you should pass 1 to <code>chn</code>, 1 to <code>ctl</code> and 127 to <code>v</code>.<p>

Loads the patches you're going to use .
<p>
This has effect only for GUS cards, although, if you use this function when <a class="el" href="classDeviceManager.html#a29">defaultDevice()</a> is not a GUS device, it will be ignored.<p>
The parameter is an int [256] array, which contain the following:<p>
The first 0..127 integers, are the number of times each General MIDI patch will be used, and -1 when the corresponding patch won't be used.<p>
The 128..255 integers are the number of times each drum voice (each note on the drum channel) will be used, and -1 when the corresponding percussion won't be used.<p>
This is done this way so that if the user has very little memory on his GUS card, and not all patches will be loaded, they are at least reordered, so that it first loads the one you're going to use most.<p>
In case you don't worry about such users, or you don't know "a priori" the number of notes you're going to play, you can just use 1 for each patch you want to load and -1 in the rest.<p>

The parameter <code>i</code> should be in the range of 0 (nothing is heard) to 150 (music is played at a 150% of the original volume).<p>
Keep in mind that as most MIDI files already play music at near the maximum volume, an <code>i</code> value greater than 100 is very probably ignored most of the times.
