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.

Description Status Message
Set the
parametric EQ on
input 1 , band 2
to the following
parameters: type
= parametric
filter, frequency
= 1250 Hz,
bandwidth = 40
1/100th octaves,
gain = -20 dB,
S01PEQIA1,2,1,1250,40,-20,1,1
enabled = yes,
slope = 1 dB per
octave. The
value of the
slope parameter
is irrelevant for
this type of filter,
we could have
set it to
anything.
