I have SPLAT, Focusrite 18i20, and HP Envy 7.
The Sonar Documentation says the Console emulators should be placed first on the prochannels. Just curious as to why? And does the module order work better in a certain order?
I realize the answer is probably subjective in nature. However, I have found that the members on this forum give excellent insight. I am just a simple stoner metal guitarist at heart, recording my current project in a bedroom at his home. But many of you are professional audio engineers with volumes of experience and advice - which is appreciated!
Thanks!

I always leave it last in the chain.  
I don't know if it's right or wrong, but it should give add the emulator to all the FX in the PC chain.

The effect of the Console Emulators is subtle and cumulative.
You might not hear its effect on a single track or 2 but as soon as you get into 15/20 tracks territory, you should start to notice a slight difference
 
Try it with all modules at the top and listen carefully. Move them all to the bottom and listen again. If you have a preference then you'll know what to do.
 
I fond having them all at the bottom works best for me.

Like Slugbaby I have kept the Console Emulators at the bottom but only because that is how my SPLAT opens - I assume that is the default.
Bristol - you nailed it - once I get more tracks I can really tell the difference. You would think with a stoner metal project you would not have that many tracks but some of the songs end up being 30+ tracks.
Many thanks for all the help, tips, and advice guys.

All at the bottom for me too.  SSL emulation.  Channels and busses.
 

I forget, is the top first or last in the chain? 

Top is first in the chain.

It depends on where you want your audio to hit the emulated mixer and the type of flow you are attempting to emulate. In an analog studio the audio hits the mixing desk preamp or external preamp first then is recorded to the tape machine. from there it leaves the tape machine and goes back to the mixing board. From there began the compression and eq inserts. The channel is then bussed and the busses are then all summed to the master fader and finally back out to the two-track tape machine. 
 
So for simplicity you could run tape emulator first then console emulator, eq, compression, send to group/bus fader w/ bus console emulator, send to master fader w/ buss console emulator, buss compression/eq, limiter, tape emulator.
 
Also if you are recording a guitar and using software guitar amp, place that first because in the real world that happens before hitting the console/tape.
 
On the other hand if you imagine you are emulating initiating playback from a digital box to a console, or from the compiter to a mixing console and you are more interested in summing fx not real world signal flow, placing the console emulator at the end of every pro channel chain is ideal. 
 
Other than those two scenarios just put it where it sounds best and enhances the track the way you want it to.
