how can I use AudioEffectEnvelope::isActive ??

[colorado_hick]

I have an array of envelopes, and I want to look through them to find one that is not active. Below is the snippet.
The error I am getting is
"cannot convert 'AudioEffectEnvelope::isActive' from type 'bool (AudioEffectEnvelope:()' to type 'bool'"

How do I use the isActive value in a conditional? Actually the opposite of isActive?
thanks!!

AudioEffectEnvelope      envelope[7];


  int i_return; 
  for (int i = 0; i <= 6; i++) {  // look at each envelope
    if ( ! envelope[i].isActive  ) {  // see if it is active
     i_return = i;
    break; // no reason to keep looping
    }
  } // for loop

figured it out, I was missing the parenthesis

 if ( ! envelope[i].isActive()  )
