INDIVIDUAL PARAMETER LOCATION FUNCTION AND PAGE VALUES
The following lists give the parameter locations and ranges for each of the effects in each of the configurations.
The parameter associated with a particular function and page may be dependent on both the current
configuration, and the current mode of the effect (e.g., chorus, phase, etc.). In conditions where a page relates
to different parameters depending on the mode of the effect, the parameters are listed in tables under each
mode. All parameters are offset binary values. This means that a signed parameter with a range of -99 to +99
in the display is actually stored as 0 for -99, 99 for 0, and 198 for +99.
