MP25
CLUB MIXER
USB Drivers
The MP25 includes high-performance, high-stability ASIO and
Core Audio device drivers. The driver allows audio applications
to play and record audio via the MP25's five stereo playback
and six stereo record USB channels. The drivers are designed
for incredibly low audio latency, eliminating perceptible delay
between control input to audio applications and the resulting
audible effect.
Applications may also connect to the MP25 MIDI Out and
MIDI In ports. Control changes on the mixer's front panel are
sent out the MIDI Out port. Some mixer features may be con-
trolled by sending MIDI messages to the mixer's MIDI In port.
Change the MIDI channel number for MIDI In and MIDI Out
messages using the driver's control panel.
The driver is available on the MP25 installation CD that is
shipped with the mixer. Of course, the latest driver can always
be found at www.rane.com/mp25.html.
ASIO (Windows)
The MP25 uses a low-latency, multi-client, ASIO device driver to
interface with applications on Windows operating systems.
Multi-client ASIO allows different audio software applica-
tions to simultaneously stream audio to and from the MP25. If
the same playback channel is selected in more than one applica-
tion, the driver mixes the audio from the different applications
before streaming it to the mixer.
Installation
1. Locate the setup executable, either on the installation CD or
where you downloaded the driver from www.rane.com.
a. 32-bit Windows: RaneAsioMp25x86Setup.exe
b. 64-bit Windows: RaneAsioMp25x64Setup.exe
2. Connect the MP25 to your computer, and power on the
MP25.
3. Double click the setup file.
4. Follow the prompts on the screen.
5. Reboot your PC, and you are ready to go!
Uninstall
The MP25 ASIO drivers may be uninstalled from the Windows
control panel. Open the list of installed programs then locate
and double-click "Rane MP25."
Windows XP: Start -> Control Panel -> Add or Remove Pro-
grams -> Rane MP25.
Windows Vista: Start -> Control Panel -> Programs and Features
-> Rane MP25

Manual-6
Core Audio (Macintosh)
The MP25 uses a low-latency, Core Audio device driver to inter-
face with applications on Macintosh operating systems.
Installation
1. Locate the MP25.pkg file, either on the installation CD or
where you downloaded the driver from www.rane.com.
2. Double click the package file.
3. Follow the prompts on the screen.
4. Reboot your Mac, and you are ready to go!
Launching the Control Panel
Open the System Preferences window. Locate the MP25 in the
"Other" section, and click the MP25 icon to launch the panel.
Control Panel
The MP25 driver control panel allows you to set some prefer-
ences for your MP25 Mixer. There are three pages in the control
panel: Preferences, PGM Inputs 1-4, and MIDI Channel Selec-
tion. You can switch between these pages by pressing the button
in the upper left-hand corner. The button displays the name of
the next page.
Preferences
The Preferences page allows you to control these features:
• 2-Band Headphone Tone Controls adjust the level of head-
phone output high and low frequencies from +6 dB to Off.
• USB-6 Record source selection routes the specified signal
within the MP25 to the USB-6 Record channel. The available
options are Main Mix, Mic 1, and Mic 2. Main Mix is the
default setting.
• Button backlighting is on by default, but may be turned off
using the Button Backlight control. When the backlight is
on, buttons toggle between dimly lit and fully lit. When the
backlight is off, buttons toggle between dark and fully lit.
• The USB driver buffer size may be increased to achieve higher
stability at the cost of higher latency. The MP25's drivers are
designed to run very reliably at latencies below 10 millisec-
onds. However, computer performance and available resources
(number of applications running) may adversely affect the
computer's ability to stream audio reliably. If pops and clicks
are heard in the USB audio, try increasing the buffer size to
eliminate them.
• If the MP25 firmware installed on your computer is newer
than the firmware in your MP25, the Update Device Firm-
ware panel is enabled. Pressing the Update Firmware button
will update the MP25 firmware to the newer version installed
with your driver.
PGM1-4 Inputs
• The
controls on the program strips each have two Filter
Filter
Resonance values. The Filter resonance may be set High or
Low using the control panel.
