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.
