ENGLISH
 "SMART" RANDOM ON A USB-drive:
This is the "smart" random function where you have full control over which folder, genre, album or artist
you want to play in your random selection, perfect for background music in restaurants, shops, clubs &
bars without a dj. This is how it works:
 Open the fader for player1 on your audio mixer.
 Press the SOURCE SELECT-button (18) of player1 to choose one of the USB-drives.
PLAY ONLY TRACKS FROM 1 FOLDER
 Press & turn the TRACK-knob (9) to select the "Std" search-key.
 Press the FOLDER button (8), the display will show the currently selected directory name.
 Turn the TRACK knob (9) to select the directory you want to play files from.
 Press the RELAY-button (16) for about 2seconds until the LED starts blinking.
 Press the PLAY-button to start random playback only from the selected folder.
PLAY ONLY TRACKS FROM 1 GENRE
 Press & turn the TRACK-knob (9) to select the "Genre" search-key.
 Press the FOLDER button (8), the display will show the currently selected genre.
 Turn the TRACK knob (9) to select the first letter of the genre you want to choose.
 Press the RELAY-button (16) for about 2seconds until the LED starts blinking.
 Press the PLAY-button to start random playback only from the tracks of the selected genre.
Remark1: to play only tracks from a certain artist or album, just repeat the actions but select the artist
or album search-key.
Remark2: please note that the "SMART" random function will only work properly on condition that you
ID3-tags are well maintained. A perfect "freeware" ID3-tag editor for this task is called "MP3TAG" and
can be downloaded from www.mp3tag.de !
 PITCH BENDING:
This function is used to synchronize the beats of two tracks. This can be done in two ways:
 PITCH BEND buttons: The speed increases or decreases respectively as long as the PITCH BEND+
or PITCH BEND- buttons are pressed.
 JOG WHEEL: During play mode the JOG WHEEL will temporarily bend the pitch of the music by
turning the JOG WHEEL clockwise to speed up or counterclockwise to slowdown. The rotation speed
the JOG WHEEL determines the percent of pitch bend.
 PLAYING/RECORDING CD-R and CD-RW:
Apart from normal audio CD's the USB2.2 can play both CD-R (CD recordable) and CD-RW (CD
rewriteable). Please note that you should always use the "disc at once" and "track at once" disc writing
options! Although the USB2.2 is capable of reading CD-R and CD-RW recorded at higher speeds, we
suggest not using recording speeds more than x12 to increase readability. Always buy good quality brands
for CD-R and CD-RW!
If the disc is multi session, it will only play the first session:
 if the first session is CD-DA you can only play CD-DA tracks.
 if the first session is MP3 you can only play MP3 files.
ABOUT LOOPS:
 CREATE A LOOP:
While a track is playing, press the LOOP IN button to program the start point of the loop. Now press the
OUT button to program the endpoint of the loop. The seamless loop starts playing at once. (With some
practice you will be able to create perfect loops!) While the loop is playing, you can press the OUT button
again to exit the loop and continue the rest of the track.
It is possible to program a new loop, even when the current loop is still playing. While the loop is playing,
simply press the LOOP IN button to set the starting point of the new loop. Now enter the endpoint by
pressing the OUT button. Your new loop is programmed and playing.
 RESTART A LOOP:
This can be done in 3 ways:
 When a loop is programmed and you left it by pressing the OUT button, just press RELOOP to restart
the loop.
 When a loop is programmed and you left it by pressing the OUT button, just press OUT again to restart
the loop. The point where you pressed OUT is now programmed as the new endpoint of the loop.
 When the loop is still playing, press the RELOOP button to restart the loop immediately. You can
repeat this several times to create a "Stutter" effect.

 EDIT A LOOP:
When a loop is programmed, press the RELOOP/STUTTER button for about 2 seconds to enter "loop edit"
mode. While the loop is seamlessly playing, the display shows the time information of the loop endpoint.
Use the jog wheel to set the new loop endpoint. To make things very easy you can hear your modifications
to the loop endpoint continuously. When the loop is perfect: press the LOOP OUT button to save the new
loop endpoint.
