What was not said is that you need to make sure the MIDI connection is detected and selected in Sonar Preferences.
 
So in Sonar go to "Edit > Preferences > MIDI - Devices" then make sure all MIDI devices are selected. If the only MIDI connection is through your soundcard (which would be a big round "DIN" MIDI cable) then those connections should be listed. Make sure there is a checkmark beside them.
 

 
Yes, I check mark my audio interface MIDI box.
both oh them (input and output),
there is another one in Outputs list, but it doesn't checked. (Microsoft GS Wavetable Synth).
I already try to mark him to but then there some popup window with with some message.
(I could put here screenshot, but it doesnt let me do that here in this forum)

Now on the MIDI track you insert (using the "Insert Softsynth" dialog) make sure the "MIDI Echo" button is enabled so it can receive live input from your controller. This button looks like a dot with half circles coming off of it (almost like an "Explosive" warning label on an arosol can but not really). Without that on you won't be able to hear it.

 
I this that I understand what you meen, and I also check that this is marked to.

If you don't get signal from the controller you may need to go to the track "Input" dropdown menu and select "Omni". This will make the track accept all incoming MIDI signals so you don't have to worry about specifying channels.

 
I did that and nothing happened.

If you use the Insert Synth dialog to insert the SI Strings synth (or any other synth) then everything should be routed automatically so aside from the things I mentioned it shoudl all work.

For now nothing is going well :(
I tried to insert the SI Strings synth and nothing happened.
 
What can I do now?
 
 
 

Someone???

In your first post, you said you managed to create a Simple Instrument Track and the Strings plugin appeared, but no sound was produced if you click on the keyboard at the bottom of the plugin window.  (Let's worry about your real keyboard later).  The track's meter in Track View or the Console View probably showed no activity either.
 
Is your track's "Input Echo" button ON (blue) ?  It's the fourth button right under the name of your track in Track View.
 
Click it ON then click on the plugin's keyboard.  Does your track's meter now show activity ?
 
Let us know if you've made it this far and we'll go from there.
 

 
What are you using for audio output ?  Do you have speakers/monitors or headphones hooked up to your Tascam interface ?
 
If so, yave you configured your Tascam for audio output ?  Are you using its ASIO driver ?
 
In Preferences / Audio / Devices, is your Tascam selected under "Output Drivers" ?
 
 
 
 

The answers for the to two posts you wrote me are:

1. I can hear sounds when I click on the keyboard at the bottom of the plugin window, with ot without the "Input Echo"  button ON (blue). (I tried the two situations).
I saide that I can't here any sound when I click on "Record" and try to actually record some strings sounds from the keyboard at the bottom of the plugin window. (and of course, I firs aremed the track that created when I added the "string secrion" and I want to record it.)

2. I'm using my audio interface "Tascam 2X2" for input and output. 
    I have speakers that hooked up to my Tascam interface from the back (monitor outputs), and  I no hooked             up to the headphones input.(Here too, I tried the two situations)?

3. I configured my Tascam for audio output, and I'm using ASIO driver.
    My Tascam is selected under "Output Drivers".
    In this section (Preferences / Audio / Devices), in the input and output list I can see only my Tascam audio             interface, and in both of them it checkd and mark.
 

@ 1: 
You're not supposed to record anything using the VST UI keyboard. It does not work. If you don't have a MIDI keyboard you write your music either in Piano Roll View or Staff View.

Good !  You're half way there.

That's normal.  We couldn't record like this until recently and you can't with your Sonar LE.
 
Now, set your Instrument Track's "Input" to your Roland keyboard.  You can do this in the Track View by selecting "I/O", "Custom", or "All" in the list to the right of the 'clock' in Track View (make sure the track is wide enough so the Input selector is not hidden), or in the Inspector (hit "I" if it's not already visible), or in the Console View.
 
Here's a view of the Input selector in Track View, but the button is the same in all views.
 

 
It's the one with "I" in a white box and -None- as its value.
 
Click that.  Do you see your Tascam interface  in the list of possible inputs ?
 
If yes, select the Tascam + "MIDI Omni" for now.  Can you now hear something (or see meter activity) when you play your Roland keyboard  ?  If you can, then recording should now work.
 
If not, we'll have to go further from here.
 

So, 
I did the things the way you told me,
But you didnt tell me what kind of Synth Instrument Track to add, MIDI or  Symple,
So I tried rhem both, and unfortunately it is still dont work.
I can't hear something (or see meter activity) when I play on my Roland keyboard.

He was saying do that on the track you already had working (the one where you had the synth inserted and could get sound from the synth's interface page).
 
So insert your synth the way you did before (the way that worked) then use that Input dropdown to select the MIDI inputs coming from your interface/keyboard.
 
You should really go through the Tutorials at the start of the manual and then navigate to the more in depth explanations in the manual.
 
You should also give the manuals for your keyboard and your interface a read through to make sure there aren't any little tricks or insights holding you up.
 
I'm not going to say these things are "simple" because they aren't but pretty much everything you need to know has been posted here. I think you need to work through it methodically and really understand the fundamentals of what is going on and why. Something, somewhere in the various documentation the answer will reveal itself.
 
That's not meant to be dismissive or rude but I think the process is getting jumbled on your end somehow and some hard study time of the manual(s) should clear it up.
 
FWIW it took me over a year to full understand the interplay between my external MIDI devices, the synths and the tracks in Sonar.
 
If one thing screws up... nothing works. Without looking at your setup I don't think I (or anyone else) could help much more than simply repeating what has already been covered.
 
Good luck.

There is no other kind of "Instrument Track" other than "Simple".
 
There are in total 3 kinds of Tracks :  "Simple Instrument", "MIDI" and "Audio".
 
Let's start again. Delete all tracks in your existing project or create a new default project.
 
Select in Sonar's main menu "Insert" + "Soft Synth" + "VST2" + "SI-String Section".
** In your version of Sonar the sequence may not be quite the same.
 
This dialog box will appear, and set yours to be the same.  Then click OK.
 

 
A "Simple Instrument Track" will appear in your Track View and the SI-String Section plugin will open.
 
Go back to message #27 above and set this track's "Input" as described and let us know what happens.
 
Beepster has some good points to ponder.
