The paramters are specified in the order shown and are separated by commas. The wildcard
character, *, may not be used for any of the parameters listed above. If an attempt is made to set
one of the parameters outside the valid range, the command will fail and return an error message of
ERROR#002.
Not all of the parameters are valid for each of the filter types. The following table shows which
parameters are used in each of the filter types.

When a parameter is invalid for a given filter type, the parametric EQ commands will still set that
parameter, however its value will not be used for filter computations. This valid/invalid parameter
information above is provided mainly as guidelines for programmers writing control software for the
Vortex. If a parameter is not valid for a specific filter type, then the control for editing that parameter
should be disabled or removed when that filter type is selected.
This command is saved to non-volatile memory only as part of a preset. The state of this command
will be restored after power-up only if a preset is saved and that preset is set to be the power-on
preset.
