 * Describes how a parameter's value is controlled via another

 * uses the parameter value.  When the controller is at its max, the
 * synth uses the morph "max" value (which may be above or below the original
 * parameter value).  When the controller is somewhere in between, the
 * parameter value is proportionately between the two values.

 * Fix soon:
 * - is ParmValidator needed?  not being used now
