SAMPLING2 / LOOP CHECK
----------------------

Allows visual inspection of how well loop points are placed through a sample, to result in a smooth loop.

A valid V2 sample shall be provided at the Sample2 input pin.

The output sample is intended for display purposes only, and shall be sent to a Sample Display module (read-only); it is composed of 'Width' samples in its left half, up to and including the End point, proceeding with as much samples on the right half, from and including the Start point.

Often inspecting the continuity of the derivative (y'(x)), or even of the second derivative (y"(x)) of the resulting signal, is much more effective than inspecting the signal itself (y(x)). A Patch Memory List with suitable List Chooser should be connected to the Display Type Choice and Display Type List, to select what to display (or even custom switches  operating on the Choice pin only).

The goal is adjusting the loop points so that pretty no spike is visible at the center of the second derivative of the displayed signal.

For convenience, the output is *always* normalized to 1.0; therefore, you should set the range of the display to 10 V.

The output is updated every time any input pin is changed.
