Is there a way to take an effect of clicking run button in the AWE designer GUI using a command in MATLAB

Thanks a lot! That works. But I still have some issues to address, maybe I can ask you more about. What I would like to do is change a tuning parameter every 0.1 sec over 10 sec duration of input WAV file ( since I need to use a WAV file as input). Let's say I have this 'example.awd' layout where I have a biquad filter and I want to change the frequency from 100Hz to 1100 Hz . The input WAV file is specified in 'Layout property' menu from the AWE designer and there 'Record output' is checked to write the output as WAV file. What I 've been trying is  

- load example.awd in AWE designer

- From MATLAB script (Pseudocode)

     awdname = 'example.awd'

    GSYS = get_gsys(awdname);

    process_menu_event('OnBuildAndRun')

    for i=1:100

     GSYS.SYS.FIlter.freq = 100+ i*10

     set_gsys(GSYS, awdname);

     pause(T) ; % T is the interval chosen to make sure i=1:100 increment is synced with 10sec WAV file duration.

    end

    process_menu_event('OnReturnToDesignMode')

Questions are 

1. Specifiying the "Layout property' would be the only to choose an input wav file to feed the .awd layout, also output file?  audio_sever_command('audio_pump, *.wav') looks like letting you choose the file but as I already asked this doesn't seem able to control the AWE designer...

2. Would there be a good way find 'T' value (please see the pause(T) and the comment next to it in the above pseudo MATALB code)? I guess If have a exact clock rate used to update .awd from the MATLAB script (I am not sure though).

3. Actually the approach I described didn't work. It seems like the param value(freq) in .awd is not updated as expected (from What I see in the AWE design GUI). Overall, it would be great if you verify the pseudocode above is an legit approach, Otherwise could you enlighten me?

Thank you!

Thanks for your suggestion.
There is no reason to stick with the approach above. 
More questions are ( as a beginner )

1. Can I track/change the frame incoming rate in the designer?
 For example, like in my example above, to change the parameter value every 0.01 sec for 10-sec audio,
You would first know how Audio weaver handles audio buffering for forming input frame, if there is an overlapping, hopisze, framesize.

2. In the above example, instead of increasing the biquad peak frequency by 10Hz, Would I be able to set up a look up table and refer that table for frequency chage?
I would want to have a table that contains 100 values which describes the time evolution of the peak frequency.

Thank you very much!
