VINYL MODE

Pressing the VINYL (21) button enables VINYL mode and 
illuminates the Vinyl indicator on the jogwheel display. 
Enabling VINYL mode allows scratching when the JOGWHEEL 
(27) is touched and rotated. When VINYL mode is disabled, 
the JOGWHEEL (27) will be in SEARCH MODE and will allow 
searching through the track.

PITCH NUDGE

It is possible to increase or decrease the pitch temporarily by up 
to 8% by using the platter.  If the platter is in VINYL mode, then a 
pitch nudge can be done by turning the platter by touching only 
the outer (rubber) edge.  If VINYL MODE is off, then you can turn 
the platter from anywhere (including the top) to nudge the pitch.
You can also create a temporary pitch increase or decrease by 
using the PITCH BEND buttons (25).

reverse direction at the same speed as the forward playback.

jogwheel. For a stiffer and heavier feel, rotate the JOG ADJUST 
(7) rotary to the left. For a looser and lighter feel, rotate the JOG 
ADJUST (7) rotary to the right

JOGWHEEL START TIME

Adjusting the START TIME (18) jog mode adjustment adjusts the

and decreases when turned counterclockwise.  This parameter 
does not affect cues.

To use SLIP while scratching, enable VINYL mode by pressing 
the VINYL (21) button. Enable SLIP mode by pressing the SLIP 
(22) button. Using the jog dial will now create scratch effects

from the playback position playing underneath.

the SLIP (22) button. Set a loop using the IN / OUT controls and 
loop playback will begin. The SLIP (22) button will begin 
flashing indicating SLIP mode is active and the position playing 
underneath is shown on the jogwheel display. Upon exiting the 
loop, track playback will continue from the playback position 
playing underneath.loop playback will begin. The SLIP (20) 
button will begin flashing indicating SLIP mode is active and the 
position playing underneath is shown on the jogwheel display. 
Upon exiting the loop, track playback will continue from the 
playback position playing underneath.

SLIP WITH REVERSE

To use SLIP with reverse playback, enable SLIP mode by 
pressing the SLIP (22) button. Press REVERSE (6) to begin 
playback in the reverse direction. The SLIP (22) button will begin 
flashing indicating SLIP mode is active and the position playing 
underneath is shown on the jogwheel display. Press REVERSE 6) 
again to exit reverse playback. Upon exiting reverse playback, 
track playback will continue from the playback position playing 
underneath.

Ethernet.  You can enter into Link Mode by pressing the LINK 
(17) button on one or more players.  In Settings, you can use the 
PLAYER NUMBER parameter to either set all connected units to 
AUTO, or to define the numbers manually.  Link mode enables 
connected players to share the same single library, as well as 
synchronize tempo between players. 

When devices are linked, you will see an icon in the MDJ-900 
display that indicates link status.  See the image table below…

Icon Dark - No connected players and
LINK unavailable

Icon Blue – Link Active and available.

Icon Blue with Red – LINK connection is 
active and busy.

There will also be a number (1-4) next to the icon to indicate 
what player number that unit has been assigned (either 
through SETTINGS or automatically if set to AUTO).
