Thanks Paul, these are really fine programs but mostly for playing stereo music. I need to play mono, stereo and 4 or more channels files on a headless system so it's a bit of a corner case application... please count me in as an alpha tester for the or more scenario :) I would certainly appreciate your feedback on this but you have to know that: 1. the player is a shared library loaded at runtime; 2. you will need QT; 3. I only have a minimalistic gui to load and test the player; The player works for what I need it to but I plan to implement some 'features' to allow routing of the sound file channels to the player outputs, it is currently ch i to output i. If you already have ideas about what would be needed, I'm all ears. Drop me a mail if you still want to alpha test...

How do you control the decks? mouse, key shortcuts, other? You select a file and press play. You could also press F9 .. F12 to start/stop the decks. Or you own a studio surface which sends joystick button press/release events. If you have a USB joystick, simply connect it. Press Button 1, and it plays deck 1, release button 1, and it stops. Of course, you can also press Buttons 1-4 simultaneously to have all four decks playing at the same time. ;) Selecting a new file while one is playing queues the new file. Press stop or wait for the current one to finish to actually play it. (it's a safety for radio stations, so they're not accidentally stopping the current playback). Same for stop: program only quits if you stop all four decks and then press Ctrl+q. Well, the window-close button is a shortcut, but it wouldn't be visible in fullscreen mode.
