[Challenger Prime Macro Issues]

So I just purchased the challenger prime for one reason it was a decent priced macro keyboard.

 

The first problem I encountered is I cannot seem to find a way to tell the macro how long to hold the key, only the delay between strokes. Why can't I have it hold the forward arrow or W key for a certain amount of time.

 

Secondly, why does the macro not allow two key presses at the same time? Example: Moving forward while turning left at the same time. (Running in a circle while in game).

 

Thirdly, if I hit the macro key, why does it deactivate the macro when I hit any other key on the keyboard?

 

Ultimately, what I am trying to do is this:

 

Hold E down (which strafes my character) while holding the A key (which turns me left) for a certain amount of time. This would make my character run in a circle. The time I set to hold A down would determine the tightness of that circle. I then want to be able to (while the circle macro is running) manually hit a key say 1.

 

Does this keyboard simply not support the features mentioned above or am I missing something.

 

Thanks for any support or suggestions.
