Team,</span></font></div>
<div><font size="2" face="Arial"><span></span></font> </div>
<div><font size="2" face="Arial"><span>I've been thinking
about this panning thing, and I came up with the following very simple pot-based
panning circuit:</span></font></div>

of this circuit are shown below, and compared with sin and cos
responses:</span></font></div>

<div><font size="2" face="Arial"><span></span></font> </div>
<div><font size="2" face="Arial"><span>I believe that I can
create a voltage-controlled version of this simple pot panning circuit fairly
easily by replacing the pot with a pair of modified Irwin 2164 circuits. I
did this for the Morphing LFO.</span></font></div>

<div><font size="2" face="Arial"><span>Would this response
suffice as an "equal power" panner?</span></font></div></div>
