Its uncertain the level of complexity you are operating at so, without making any assumption, I will answer your exact question, which was to get sounds from the Fantom x from a midi track in Sonar..
1. You need to direct the Sonar Midi track to the Fantom X. ...I assume that you have the Fantom X input port enabled in Sonar>Preferences>midi>devices>input as you are playing softsynths, so enable the Fantom X in Sonar>preferences>midi>devices>output.
2. Direct the midi track output to the Fantom X midi port, ch 1.
3. Whatever patch you have selected in patch mode of the Fantom should sound.
If you wish to record that into the project then insert an audio track and record the Fantom X output.
Good advice above is to create a track folder, and if you are using performance mode, use one midi track per Fantom Channel... Add one audio track per channel (though you will need to record one audio track per run-through) then save this as a track template... go nuts and find a bmp of the Fantom X and create a track icon :)
You have 3 choices for saving projects..
1. record everything as audio and be done with it.. downside is that you cannot edit the data as you will not have recorded the patch assignments..unless you make paper notes.
2. save the patch/edit settings in a performance on the Fantom X.. load this performance when you open the Sonar project.
3. Save any user/edited patches in the Fantom X, and save the locations in the individual midi tracks as PC (program change) information.
4. Do 2. above and recall the performance setup in the sonar project.
To get fancy, and recall the preset sounds by name (doesnt work for user sounds) the ins file referred above is a script with these names so that you can select the patches via a mouse... personally (I have Fantom G) its quicker to dial them in on the synth, but the file for the fantom X is here..

Currently using my Roland Fantom FX as a MIDI keyboard, and then using various virtual synths to produce sounds in Sonar. This works well but I have some sounds in my Fantom that I would like to use in Sonar. How do I connect my Fantom sounds to the midi notes I produce in Sonar? Probably a simple explanation but I am in the dark.
Midi and analog connections from Roland FX external synth connected to Tascam 1884, then to computer. Tascam firewire to computer.
