Use Vintage Clav Stereo Spread in MainStage
Unlike the original D6, Vintage Clav has a stereo output that you configure with the Stereo Spread parameter. It is divided into two halves Key and Pickup.

Drag the Key parameter to set a key scale modulation of the panning position. In other words, the played keyboard note position determines the panning position.
Use the Pickup parameter to spread the two pickup signals across the stereo spectrum when both pickups are active (Upper+Lower or Upper-Lower modes).
You can use both spread types at the same time. They are automatically mixed. The ring around the Stereo Spread button graphically displays the effect of both parameters, as follows:
The key scale range is indicated by orange areas in the ring.
The pickup panning position is indicated by red lines in the ring.
