Novation A-Station - EQ Filter Controls

The EQ frequency set point determines where in the sound
spectrum the boost or cut occurs. It may be moved anywhere
from very low frequencies (0 = less than 10Hz) to very high fre-
quencies (127 = above 20,000Hz)
To change the EQ frequency, ensure the function switch is set
to SHIFT. Repeatedly press KEY 4 until the display shows E F
and an alternating value. Adjust the PORTA/DATA knob for the
desired EQ frequency.
EQ Depth
The real power of the EQ filter is the ability to move the EQ fre-
quency set point automatically with the dedicated LFO. This
control dictates how intense the movements are from the LFO.
Any amount of depth will result in EQ changes at the rate deter-
mined by the EQ rate control.
To change the depth, ensure the function switch is set to
SHIFT. Repeatedly press KEY 4 until the display shows E d
and an alternating value. Adjust the PORTA/DATA knob for the
desired EQ Depth.
Determines the rate (speed) of the dedicated LFO. This LFO is
able to modulate the EQ frequency (see EQ depth). To change
the rate, ensure the function switch is set to SHIFT. Repeatedly
press KEY 4 until the display shows E r and an alternating
value. Rotate the PORTA/DATA knob clockwise to increase the
rate and anticlockwise to decrease the rate.
EQ Sync
The rate (speed) of the LFO may be locked to the tempo of the
musical piece to allow auto EQ Filtering effects.The table on the
Page 27 describes the musical timings available.
Set to o F and the LFO speed will be at the rate determined by
the EQ RATE (see above). Set to any other selection, the LFO
speed will be in time with the selected musical timing. This
works in similar way to Delay sync (refer to Page 26 for infor-
mation on setting up this feature).
EQ Initial Position
As well as being able to synchronize to MIDI clock (tempo), the
dedicated LFO used to modulate the depth of the EQ may have
its initial position set after a specific MIDI event is received such
as program change of Start Song (see page 53- Global menu
options).
To change the EQ Initial position, ensure the function switch is
set to SHIFT. Repeatedly press KEY 4 until the display shows
E k and an alternating value. The initial positions are shown in
the table on the following page. For example, if the desired
position is to start moving upwards then set to L o (Low). After
a MIDI event the LFO wave will start to climb from this low
