   My application is using one triangle lfo to modulate a voltage
   controlled panner, with the other controlling overall level.  So
   the signal appears to start on the left, the get louder as it
   reaches the middle, fades back to half on the right, fades to zero
   in the middle, then back to the start. 

   So you have a 'circular' effect (taking overall level as
   front/back).   

   Now, sine is wrong for this! I think!

I think sine is perfect for this.  Sine is *defined* by a circle.
