Advanced Features
The EQ Menu
Contained in the Effects section is an EQ (Equalisation) Filter which
can boost or cut high (treble) or low (bass) frequencies in a similar
manner to the ‘tone’ controls often found on domestic hi-fi units.
As well as being able to boost low or high frequencies, the final output
EQ Filter may be used to create automatic sweeps of EQ and filtering.
EQ processing may be synchronized to tempo and locked to musical
timings from 32nd triplets through to several bars.
Use the PAGE up/down buttons to scroll through the Menu functions
available - See table below.
Frequency (Menu Page 1)
The EQ frequency set point determines where in the sound spectrum
the boost or cut occurs. The Frequency point may be moved any-
where from very low frequencies (0 = less than 10Hz) to very high fre-
quencies (127 = above 20,000Hz)
To change the EQ frequency, select Page 1 in the EQ Menu. Adjust the
DATA knob for the desired EQ frequency.
Mod Depth (Menu Page 2)
The real power of the EQ filter is the ability to move the EQ Frequency
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 determined by the EQ rate control.
Note : The dedicated EQ LFO should not be confused with the two
LFOs available on the K-Station’s front panel.
To change the depth, select Page 2 in the EQ Menu. Adjust the DATA
knob for the desired EQ Depth.
Mod Rate (Menu Page 3)
Determines the rate (speed) of the dedicated EQ LFO. This LFO is
able to modulate the EQ frequency (see Mod Depth above). To
change the rate, select Page 3 in the EQ Menu. Rotate the DATA knob
clockwise to increase the rate and anticlockwise to decrease the rate.
Note : The dedicated EQ LFO should not be confused with the two
LFOs available on the K-Station’s front panel.
Sync Mod Rate (Menu Page 4)
The rate (speed) of the dedicated EQ LFO may be locked to the tempo
of the musical piece to allow auto EQ Filtering effects.The following
table describes the musical timings available.
When a sync interval is selected, the tempo of the EQ Filter sweep is
controlled by the Arpeggiator’s TEMPO knob when MIDI Clock Source
is set to INT, or by the external sequencer’s tempo when MIDI Clock
Source is set to EXT. See Page 35 for information on changing the
Global MIDI Clock Source.
When controlling the EQ Mod Rate from a sequencer, it is important to
ensure that the sequencer is transmitting MIDI Clock messages.
Consult your sequencer manual for details.
Note : When the Sync Mod Rate is set to OFF, the timing of the EQ
sweeps will be controlled by the setting of the Mod Rate. Any incoming
MIDI clock messages or Arpeggiator TEMPO settings will be ignored
by the EQ effect.
LFO Sync Initial Position (Menu Page 5)
As well as being able to synchronize to MIDI clock (tempo), the dedi-
cated 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 or Start Song - see the Global Sync Mode function on Page
35).
To change the EQ Initial position, select Page 5 in the EQ Menu. Use
the DATA knob to select one of the initial positions shown in the table
below.
For example, if the desired position is to start moving upwards then set
this function to LOW. After an appropriate MIDI event, the LFO wave
will start to climb from this low position. Set to MID and it climbs from
the centre of the waveform.
Note : The dedicated EQ LFO should not be confused with the two
LFOs available on the K-Station’s front panel.
Setting The EQ Amount
Setting of the EQ cut / boost amount at the EQ Frequency position is
done by altering the LEVEL knob in the Effects section of the front
panel. See Page 20.
