Description
This unit lets you (flexibly) turn any sample into an interpolating lookup table. If you understand the Bump Scanner, then the Sample Scanner is exactly the same with the (entire) sample taking the place of the bump.
In the figure above, a sample containing a single cycle of a sine wave has been loaded into the unit. The center parameter locates the sample in the unit's input range. The width parameter determines how much of the unit's input range is covered by the sample. The height parameter adjusts the amplitude of the sample values, while the fade parameter dictates the percentage of the width used to fade out the sample's edges to zero.

Don’t be fooled! This diagram above is not showing the output signal vs time. The x-axis is not time, but rather the input signal. The diagram shows how the output signal is derived from the input signal. The graph should be read like a lookup table. |
Parameters
center
The center parameter controls where the center of the sample should be placed on the input range.
width
The width parameter controls how much of the input range the sample covers.
