Use post fade Aux 5 & 6 as the sends from ZED so when you move the channel
1
fader the effects level stays in proportion.
Select Aux 5-6 on the USB output selector switches.
2
USB lead carries the digital signals to & from the computer.
3
Select USB Device Left for Aux 3 or Right for Aux 4 as the input for the track in
4
the software package.
5
You can use a send bus in software as you would a hardware mixer.
Assign an effect from your software plug-in list.
6
If using reverb, it's a good idea to have 100% wet mix level and reduce the pre-
7
delay in order to compensate for any latency in USB.
Send the output of the software group or bus to USB Device. In this case, and
8
probably with most reverbs, it will be stereo so it will go to left & right.
9
Set the USB return to be sent to ST3. It can then be sent directly to LR or to the
stereo channel by pressing in the under-panel switch below the ST3 Level control.
