No I don't meant the dry signal option in Polar, but the dry signal of the guitar. The tone when you're not plugged to any effect or pedal. That tone is audible with the effected tone (effects of Reason).
If I play through my PodX3 pedal it's the same thing. I hear the tone affected by the pedal + the tone of Polar or any other effect in Reason. But these are two different tones at one time. Like the Dual Tone in PodX3. Normally I should hear one tone.
