I want to use the sounds from my Roland Fantom X6 in Sonar Platinum as a synth

I want to use the sounds from my Roland Fantom X6 in Sonar Platinum as a synth and I'm in need of some help with setup.

 

My current setup is:

Fantom MIDI Out connected to MOTU MicroLite MIDI In 1

MOTU MicroLite MIDI Out 1 connected to Fantom MIDI In

 

I'm not sure how to route the MIDI tracks in Sonar so they will play back using the Fantom sounds...I want to record MIDI sequences in Sonar using the sounds from my Fantom then record the audio into Sonar. I assume this should all work if I connect my Fantom's audio outs to my audio interface's audio ins?

I see from your other post that you have already done that.
Does SONAR play the sounds correctly through the keyboard?
Perhaps if you tell us how you have things routed now we can suggest alternatives. Or post a screenshot of your track routings.

Its simple and you have described it just right. Only thing which patch/channel should play needs to be setup correctly. 
Basically once you have got the MIDI connections done and tested that they work fine, select your Fantom as the MIDI input into your Sonar MIDI track or leave it as Omni if you do not have any other MIDI input devices. 
Then route the output of the MIDI track to Fantom as well. Record the MIDI from your Fantom into the MIDI track. Then when you play back the MIDI track, it will play the audio from your Fantom. 
Once you have made any edits to your MIDI track as required, you can record the audio from your Fantom into a separate audio track in Sonar after making the interface connections as you described. 

Do you have Bank and Patch set in the MIDI track pane also?
Do you currently have the Fantom's audio outputs connected to the Roland and an audio track set to that input, and Input Echo on?

i have a fantom XR and that had a sort of intermediary GUI synth type thing but was flakey when it worked on old systems and was never upgraded after XP (at least that's how I remember it). But I love the Fantom libraries-- did you know that they were mostly programmed by Mr Spectrasonics Eric Persing

UPDATE: I'm now getting sound during Sonar MIDI playback but it seems to be double-triggering each note the Fantom plays. Is there a setting in Sonar or the Fantom that will remedy this?

I've turned off Local Control on the Fantom X6 but I’m finding that with local control on the X6 turned off, I get no sound during Sonar MIDI playback.
 
Unless I turn MIDI echo off in Sonar, every time I press a key on the X6 or attempt Sonar MIDI playback, each MIDI note is triggered multiple times, resulting in somewhat of a MIDI note loop which can sometimes cause the X6 to hang/freeze. The only way I’ve found to stop this is turn off ‘Always echo the current MIDI track’ in Sonar but I’m not sure that’s really solving the problem?

Do you set the Phantom in patch mode? or performance mode? FYI, To use multi channel / multi timbral you need to be in performance mode.
