Sculpture spread controls in Logic Pro for Mac
Although they are not found in the actual Pickup display, two additional pickup parameters are available to the right of the Material Pad.
Key/Pickup Spread parameters
Key Spread button: Drag vertically to set the amount of panning (pan position) by MIDI note number. Depending on settings, the farther up or down the keyboard you play, the more the voice is panned left or right. Two lines in the ring that surrounds the Spread parameters indicate values.
Pickup Spread button: Drag vertically to spread the two pickups across the stereo or surround base. Two dots in the ring that surrounds the Spread parameters indicate values.
In surround instances, these two parameters can be affected by the Surround Range parameter. For more information, see Sculpture surround range and diversity.
Tip: You can create animated width and chorus effects by modulating the Pickup Position parameters with an LFO or other modulator.
