SOLVED sonar wants to load GM tones instead of instrument patches X3 Professional

You will need an instrument definition file for your Roland synth. You are probably selecting the default bank which is most likely GM. 

You don't load the instr def file. It has to be setup.
 
Please read the section on this in the Sonar manual starting on page 1375. Once setup you should never have to do it again.
The below is from page 1379
 To import instrument definitions
1. Go to Edit > Preferences > MIDI - Instruments.
2. Click Define to display the Define Instruments and Names dialog box.
3. Click Import to display the Import Instrument Definitions dialog box.
4. Choose the file that contains instrument definitions for your manufacturer, and click Open. SONAR displays a
list of all the instrument definitions in the file.
5. Choose one or more instruments from the list, and click OK.
6. Click Close to close the Define Instruments and Names dialog box.
The instrument definitions you imported should now appear in the Uses Instrument list in the Assign
Instruments dialog box.
