							Using a DAW other than Cubase
42     Operation Manual
Using a DAW other than Cubase
When using a DAW software other than Cubase, you can use the MR816 CSX/MR816 X simply as an audio interface having 
up to 16 input/output channels. Link-related functions such as quickly routing the input channel to an audio track of Cubase 
(page 9) are not available, but the following additional functions are available with the use of the MR Editor.
● Producing monitor mixed sound
The MR Editor lets you produce the mixed sound for monitoring, and it can be heard with no latency. 
● Using the effects built into the MR816 CSX/MR816 X
You can process audio signals of the DAW with the built-in effects on the MR816 CSX/MR816 X by setting the MR816 CSX/
MR816 X to the External Effect mode and making the settings for the bus and channels for input/output audio signals on the 
DAW manually. 
NOTE
·The settings made on the MR Editor need to be managed separately from the DAW file. If you want to manage the music data and 
MR816 CSX/MR816 X related settings as a single package of data or you want to take a full advantage of the MR816 CSX/MR816 X, we 
recommend that you use Cubase.  
						

							Using multiple MR816 CSX/MR816 Xs
 Operation Manual   
43
Using multiple MR816 CSX/MR816 Xs
Up to three MR816 CSX/MR816 Xs can be used simulta-
neously by connecting them in daisy-chain fashion to a 
computer via IEEE1394 cables. You can upgrade your 
music production system and add more audio input/out-
put channels simply by adding another MR816 CSX/
MR816 X. 
Even when multiple MR816 CSX/MR816 Xs are con-
nected, you can set parameters such as those for digital 
audio input/output, Sweet Spot Morphing Channel Strip 
and REV-X for each device individually. 
NOTE
·Keep in mind that up to two MR816 CSX/MR816 Xs can be 
connected when the Sample Rate is set to 88.2kHz or 96kHz. 
Even if you connect an additional third device, the last recog-
nized device (other than the device specified as the Word 
Clock master) connected to the computer will not be available.
·Even if multiple IEEE1394 interfaces are installed on the com-
puter, make sure to daisy-chain connect all devices to the jacks 
of a single interface. This is necessary since the computer can 
only recognize devices connected to a specific, single 
IEEE1394 interface jack, and cannot recognize devices con-
nected to different jacks of different IEEE1394 interfaces even 
though they are installed on the same computer. 
·In addition to the MR816 CSX/MR816 X, another audio inter-
face compatible with the Yamaha Steinberg FW Driver can be 
connected to an already connected device via an IEEE1394 
cable. For information about devices compatible with the 
Yamaha Steinberg FW Driver, refer to the following URL: 
http://service.steinberg.de/goto.nsf/show/
supportupdates_mr816_gb
When multiple devices are daisy-chain connected to a 
computer, a unique number (indicated at the end of the 
device name) is automatically assigned to each of the 
devices, in the order with which the devices are con-
nected. The number once assigned to a device will be 
maintained even if it is disconnected or the power is 
turned off. If you want to reset this number assignment, 
follow the instructions below.
1Turn off the power of all the connected 
MR816 CSX/MR816 Xs then disconnect all the 
IEEE1394 cables. 
2Call up the Control Panel of the Yamaha FW 
Driver window then click the [General] tab. 
3Click the [Reset Device Number] button at the 
bottom right corner of this window. 
NOTE
·The [Reset Device Number] button is available only when all 
the connected devices are turned off. When any device is 
turned on, this button is dimmed and cannot be clicked. 
4Daisy-chain connect two or three MR816 CSX/
MR816 Xs to the computer in the desired order. 
5Turn on the power of the first device connected 
directly to the computer. 
Wait until the tab corresponding to the first device 
appears on the Control Panel of the Yamaha FW 
Driver window, indicating that the computer has 
actually recognized the first device.
6Turn on the power of the second device that is 
daisy-chain connected to the first device. 
The tab corresponding to the second device 
appears on the Control Panel of the Yamaha FW 
Driver window, indicating that the computer has rec-
ognized the second device. If a third device has 
been connected to this second device, tur n the 
power on in the same manner. As necessary, set the 
Word Clock Master to the desired device.

							Using the MR816 CSX/MR816 X without a computer
44     Operation Manual
Using the MR816 CSX/MR816 X without 
a computer
Using the MR Editor on a computer enables you to store mixing balance and other related settings to the MR816 CSX/
MR816 X. This settings are available even if the power of the MR816 CSX/MR816 X is turned off and then back on again. 
Accordingly, you can use the MR816 CSX/MR816 X as a standalone mixer or D/A - A/D conver ter without the use of a com-
puter after the necessary settings on the MR Editor or Cubase have been completed.
For instructions on using the MR Editor, refer to page 33. 
NOTE
·Even when two or more devices are daisy-chain connected, all the connected devices can be used without the computer.
