Hi Joel,
Not sure what you are wanting here but you have two choices:
If you wanrt to simply pass the bass note of teh chord try choosing the Bass->BASIC 2 performance and set the speed to 0.5, This plays the bass note of the chord on my instance.
But have you explored the BASS performances?
You may also want to look at using playback performances to make more interesting bass lines. I have a Scaler state that you can down load from here and import as a template.
