DRIVER UPDATE TOOL
You can update or reinstall your drivers
later by using the Driver Update Tool. By
default the Driver Updater will be located at
C: > Program Files > Serato > driver_updater32.exe
or for Vista 64-bit systems:
C: > Program Files (x86) > Serato > driver_
updater64.exe.
1. Connect the MP 4 mixer to your computer with
the USB cable. If the Hardware Wizard shows
up, click Cancel.
2. Run the driver_updater.exe utility. If you are
asked whether to install one of the drivers,
choose Continue Anyway and the utility will
conrm that the driver has been updated.
3. On some Windows machines, each USB port
is treated separately, requiring a separate driver
install for each USB port. Follow this installation
process for each USB port you will connect to
an MP 4.
MP 4 AS A SOUND CARD
Mac

Windows
The MP 4 will be available as a standard sound card
after the WDM driver is installed. It will replace the
previous sound card and default to MP 4 USB 2
on either of the PROGRAM INPUTS. If you wish to
change to USB 1 or back to your previous sound
card when not using the MP 4:
Windows XP
1. Start > Control Panel > Sounds and Audio
Devices.
2. Click the Audio tab.
3. Make changes using the drop menus for both
Sound Playback and Sound Recording.

Note: Be aware that Windows system event
sounds (beeps, dings, etc.) will come through
your MP 4 when it is your sound card. To prevent
embarrassment, have no other applications
running. Better yet, turn off your computer’s
sound scheme:
Windows XP

Devices.
2. Click the Sounds tab.
3. Under Sound scheme, change to No
Sounds.
4. Click OK.

WINDOWS TROUBLESHOOTING
If you have a USB PCI card, your computer
may have allocated bandwith to other devices,
including your mouse, preventing Scratch Live
from recognising the MP 4. Unplug unneccesary
devices and install Scratch Live again. You may
need to temporarily move your mouse to the
built-in USB port. After installation, reconnect
USB units as needed.
If other USB devices steal bandwidth, you may
get a “interface disconnected” message when
launching Scratch Live, try unplugging and re-
plugging in the MP 4.
The ASIO Bit Depth and “Ask host to process
during callback” settings should not be adjusted
unless you are having problems.
Uncheck “Ask host to process during callback”
if you have audio dropouts. Your application may
not support an ASIO bitdepth of 32-bit. If this is
the case, there will be no audio sent to the MP 4.
OTHER DRIVERS
ASIO DRIVERS
The MP 4 can be used with third party software, as
well as the Scratch Live software that comes with
it. When you install Scratch Live, an ASIO driver is
also installed. You can use the MP 4 as a sound
card for any third party software that supports the
ASIO standard. Go to the audio interface control
panel in the third party software, and choose the
MP 4 Driver. Launch Control Panel to access
more settings for the MP 4 ASIO driver. You can
reduce the USB Buffer Size for lower latency.
