Make Sample Play At Specific RPM Only

[bigpickle 0]

Hi,

I'm trying to make a Sample play at a certain RPM band only.

 class TestSound
 {
          sound[] = {"MyTestSound\TestSound1", 1, 1, 400};
          frequency = "1";
          volume = "engineOn*camPos*(rpm factor[0.3, 1])";    
  };

I know the highlighted syntax is the control information but i dont know how to make the sample play at a specific rpm stage only and once increased or decrased past that stage no longer play.

 

Can any of the config wizards help me with this?

 

Thankyou.
