Changing the Range of the Pitch Wheel

[progkid2112]

Hi, I'm trying to change the lower range of the pitch wheel on a lead sound from down 2 half steps to down a whole octave (12 steps). However, when I change that, both the 2-half step AND the octave note sound at the same time when I pitch bend. How do I fix this? Thanks.

There must be two oscilators. Do the same thing to OSC2 Pitch
