Spiratone

The Spiratone is a form of Shepard Tone generator. It is a sonic barber pole that creates the auditory illusion of a tone that continually ascends or descends in pitch, yet ultimately seems to get no higher or lower.

It occupies the same space as the tELHARMONIC. To find it, have nothing patched to D-Gate and HOLD H-LOCK for 5 seconds. The sound will dramatically change... you've found the Spiratone inside your tELHARMONIC.
