As mentioned before, inserting plugins to single channels is possible only when the physical inputs of the console or rack mixer can be used. In a network setup (rack mixer = stagebox or monitor mixer, console = FOH) processing has to use buses, which are routed to the console via "Tape In" with USB selected as input source. For this kind of setup there is no template available in Studio One. Actually it doesn't need one, because the setup is not really difficult. Make sure that your console/rack mixer and Studio One are connected (USB + UCNET) and running. It makes sense to zero out the mixer.
Studio One:
1) Create a new "empty" song without a template.
2) Add four mono tracks, add one stereo track. Give the 5 tracks a common color.
3) Add a bus to each track. Color the buses in another common color.
4) Go to songs settings (Audio I/O), inputs. Create a new mono input, rename it to FX A and set USB to 33.
5) Add three more mono inputs (the USB channels to automatically set to 34, 35 and 36), rename the inputs to FX B, FX C and FX D.
6) Add a stereo input (USB 37+38), rename the input to 15+16.
7) Deselect USB settings for inputs L+R.
8) Go to the output page, rename "Main" to "S1 OUT" and set USB to 37+38.
9) Apply and confirm the settings.
10) Select "FX A" as input for track 1, rename track to "FX A IN".
11) Select "FX B" as input for track 2, rename track to "FX B IN".
12) Select "FX C" as input for track 3, rename track to "FX C IN".
13) Select "FX D" as input for track 4, rename track to "FX D IN".
14) Select "15+16" as input for stereo track 5, rename track to "15+16 IN". All characters will displayed correctly in DAW mode.
15) Activate the blue listen button on tracks 1 to 5.
StudioLive Mixer (preferably via UC Surface):
16) Link Mix 15 and 16, select the mix master, go to settings, select Post. Go to the next page -> Routing -> Send -> USB and select USB 37 as left send and USB 38 as right send. Set panning if needed, raise the fader(s).
17) Select FX A (settings page remains open), select 33 as USB send.
18) Select FX B, select 34 as USB send.
19) Select FX C, select 35 as USB send.
20) Select FX D, select 36 as USB send.
21) Go to Main mix level, find the four FX return channels and deselect "Main" (on first page) on each of them (A-D). This will disconnect the mixer's effect returns from Main L/R.
22) Change input source of "Tape In" to USB.
Now you should see signals coming in and going out everywhere, when you raise faders. Remember that all sends are set to postfade, which means that you have to raise the faders of the Main mix level first. The next step is to add effects as inserts to the buses.
Studio One:
23) Insert "Room Reverb" and "Binaural Pan" to Bus 1. Set pan to 200 %.
24) Insert "Beat Delay" to Bus 2.
25 Insert "Chorus" to Bus 3.
26) Insert "Flanger" to Bus 4.
28) Insert "Mixverb" to Bus 5.
29) Copy/drag "Binaural Pan" to Buses 2, 3, 4 and 5. Pan should always be the last insert.
30) Rename Bus 1 to "FXAOUT"
31) Rename Bus 2 to "FXBOUT"
32) Rename Bus 3 to "FXCOUT"
33) Rename Bus 4 to "FXDOUT"
34) Rename Bus 5 to "1516OUT". Seven characters can be displayed correctly in DAW mode.
Everything is now ready to be checked and adjusted. The goal of this approach is to replace the mixer's effects by Studio One plugins, or any plugin you might want to use. Mix 15+16 is an additional stereo FX send, which can be used for drums/keyboards/sub mixes (any non-mono signal). FX A-D are mono sends, which leads to a different result. Of course you can add more mono and/or stereo sends and additional processing in "S1 OUT".
It's worth to activate DAW mode some time, because you can adjust most of the things via the console's touchscreen and scribble scripts. In "Mix/FX Masters" the faders of insert buses are available, in "User" mode the tracks are added.
Enjoy the great sounds of Studio One!
