As the SHAPER receives input signals, it evaluates the signal's level according to its own
internal scale. When the SHAPER's Adjust value is at .25, an input signal moving from negative
full scale to positive full scale (a sawtooth) will map to an output curve with a single-cycle sine
wave shape. At an adjust value of .5, the same input signal would map to a 2-cycle sine wave
output signal. Adjust values of .75 and 1.0 for the SHAPER would map to 3-and 4-cycle sine
wave output signals, respectively. Beyond values of 1.0, some portions of the output will pin at
zero-scale.
Small Adjust values for the SHAPER can sound much like the DIST function, but larger values
will introduce dramatic changes in timbre, while DIST will have a less pronounced effect on
timbre.
The following LCD page shows the SHAPER function in the F1 block, but it can appear in other
blocks as well.
