CONTROL UNIT

1. JOG WHEEL: This jog wheel serves 3 functions depending on the mode you are working in.
 The jog wheel acts as a slow frame search (1/75sec) control when the CD is not playing but either
paused or set to a cue point. To set a new cue point, spin the wheel then press PLAY or LOOP IN
when you have determined the proper position. Press CUE to return to the "CUE POINT".
 If the track is playing and the fast search function (16) is not active, the jog wheel temporarily bends
the pitch of the music up to +/-32% by rotating the wheel clockwise to speed it up or
counterclockwise to slow it down. The amount of pitch change is determined by the speed of
rotation.
 If the fast search function (16) is active, you will be able to search at a higher speed through the
current track.
2. LOOP IN button: Allows you to set the cue point without stopping the playback (CUE ON THE FLY).
This button also sets the beginning of a seamless loop.
3. LOOP OUT button: Used to set the endpoint when looping music. The player starts to loop seamlessly
until you press this button again to exit. When a loop is programmed but not active you can also restart
the loop. The point where you press the button will be memorized as the new end point of the loop. In
loop edit mode pressing the OUT button stops the loop editing and saves the new loop endpoint.
4. RELOOP/STUTTER button: This button has 3 functions:
 RELOOP: When a loop was programmed and you have hit the OUT button, press the reloop button
to enter the loop again. To exit the loop press the OUT button. (intro and end points of the loop are
unchanged)
 STUTTER: When a loop is playing you can press this button to restart the loop at once. You can also
press this button when a track is not playing in loop. Every time the RELOOP/STUTTER button is
pressed, it will restart the music from the preprogrammed cue point. The stutter effect adds extra
creativity to your performance.
