Next, launch SONAR LE.
Click Options/Audio and click on the Drivers tab.
The Input and Output Drivers for ZED R should appear
in the option boxes. If they don't, click the Advanced tab
and check that the Driver Mode is set to ASIO.
The Input drivers are the audio sources to the computer.
Using SONAR LE, only 8 simultaneous inputs can be used
at one time and these are shown in the screenshot en-
abled in pairs. Unfortunately with the current version of
SONAR LE, the inputs and outputs are only enabled in
pairs, but the inputs can be chosen as a mono source in
the application ie CH1/2 Left would be channel 1.
The Output Drivers are the audio outputs from the
Computer. Again, only 8 of the 18 possible FireWire
channels are enabled simultaneously using SONAR LE.
If you scroll down the list of Input & Output Drivers, you
will see there are 8 ADAT input channels and 8 ADAT
output channels that can be enabled as well as choosing
from the 18 FireWire inputs and 18 outputs.
These can be enabled and used in conjunction with the 18 FireWire inputs and outputs, connecting ADAT equipment to
the ADAT input and output connectors 1-8. SONAR LE will only allow 8 simultaneous inputs and 8 outputs at one time,
so the ADAT channels will count towards that number, but with applications with a higher number of simultaneous inputs
& outputs, then the number of FireWire and ADAT
channels that can be used will be according to the table
on p24.
In order to show how to select inputs to SONAR
tracks, here is a basic Cakewalk 16 track project (.cwp).
This is created by clicking File/New/16 Track Audio.
Click on the I/O tab near the bottom of the window,
then click the expand buttons in the audio track panes.
The track 1 shows the drop down menu for the track
inputs and if we select LEFT ZED R16 CH1/2, then the
source for that track will be channel 1 from ZED-R16.
If audio is present, click the Input Echo buttons (lit up
yellow here) to monitor the signals on the Master Bus.
The output for of the track is automatically routed to the master
bus in SONAR LE, but could be routed back to your ZED-R16 using
the drop-down menu for the outputs. Note that in SONAR LE that
there are only 8 outputs available simultaneously, in pairs. If a mono
output is required then select the relevant pair and pan the output
of that track to be a mono output, so to route back to ZED-R16
channel 1, select CH1/2 and pan 100% left.
You should now be able to send audio between your computer and your
ZED-R16 using SONAR LE.
To test this, let's do a recording....
