[PD] panning abstraction or object?

[ronni montoya]

Hi list, i was wondering if theres an abstraccion or object like this in pd:
I need a pan object that when is -1 is complete silence and when is +1
is complete silence too.
when the value begins to move from -1 to +1  the sound begins to
appear in the left speaker then it moves to the right and then the
amplitude decreases in the right speaker until it arrives to +1.
Is there something like this in pd?


thanks in advance.
