What is Playa!TraX? What does it do?

Here is an example -- Playa!TraX is running idle in the system tray, not
playing music, not doing anything. You launch a full screen game,
Half-Life 2 for example, Playa!TraX on its own will immediately start
playing your Half-Life 2 playlists and loads a configuration (which you
define) that allows you to control the music (probably through a few
keys on your keyboard) without having to see the player. You switch to
another game let's say Madden NFL Football, once again Playa!TraX begins
to play your Madden playlists, and loads an input configuration so you
can control the player without having to see it, probably through a few
gamepad buttons this time. Playa!TraX will do the same for your web
browser or email client or any application or game you want. Playa!TraX
is also a great everyday general use media player.

Control player functions through gamepads, joysticks, racing wheels,
keyboard and mouse or any other combination of input devices that you
choose.
