major modes . it should be not necessary to define
new modes.
What are "major modes"?
<p>
The idea of the major modes, is that this is a very
general description of an abstract cd player.
When the decoder works yaf send these
major modes to the frontend.
<p>
These Major modes describes the basic commands which
every yaf-decoder implementation should support:
<pre>
on/off
open/close
pause/play
</pre>
Thus it is possible that a frontend works with
a decoder even if the frontend does not fully support all
the commands (e.g: switch to mono etc...)
<pre>
If you think you have a new "mode" its almost a "feature"
eg: You have a command "jump" but this is not a "mode"
because you can press "jump" on your cd player even
if the cd player is off OR on OR playing OR paused
In all these cases the command does not affect the
state of your cd-player. Or do you have a player
which switches itself on if you press e.g. "Track 1" ?
</pre>

off: the cd player is switched off (/dev/dsp is unlocked)
on : (you may play the inserte cd) (/dev/dsp is locked)
playing: cd player plays something (player is switched on)
pause: does not play "
open track : think of it that you "select a track" you
can only open a track if the player is "ON"
close track: eject the cd from player.
