Using the EQ Filter Effect
One of the most powerful ways to use this effect is to automati-
cally open and close the filter in time with the musical piece.
The easiest way to listen to this effect is to play a sound with
this feature setup. Select a sound (a bright lead or string type
sound is ideal for this example).
For this effect, the filter must be set to mimic a low pass filter
that opens and closes ('sweeps' up and down the frequency
spectrum)
Select the EQ FREQUENCY option (page33) and set it to 5.
Select the EQ AMOUNT option (Page 32) and set it to 63.
Play a few notes and listen to the sound. It should be a very
muted bassy sound. This is because the EQ filter is cutting
most of the frequencies above the set point and boosting those
below.
Select the EQ FREQUENCY option again and while playing the
keyboard, adjust the value and notice how the sound becomes

decreases. Set the EQ FREQ back to 5.

Select the EQ DEPTH option (Page 33) and set it to 30.

Select the EQ RATE option and set it to a medium speed.
Centre
High While playing, notice how the sound automatically becomes
brighter and softer in time with the speed of the LFO (If there is
no effect, select the EQ SYNC option and make sure it is set to
o F). The final step is to synchronize this with the musical
piece. With a sequencer connected and sending MIDI clock
information, (see page 26) set the EQ SYNC to the desired
musical timing (See page 27 for listing of timings available).

Vocoder

Vocoder sounds have recently returned to popularity and are
being used more frequently in modern Pop and Dance music.
In order to hear a Vocoded sound, recall one of the factory pre-
set sounds (Bank 2 259,269 and 279) and experiment by
entering the Vocoder Menu (Press KEY 5 when in SHIFT
mode) and tweaking the settings.
All the factory presets require an external audio input such as a
microphone to be connected to the external Audio Input jack on
the rear panel (See pages 54,55 and 58 for setting up).
To listen to the sound, simultaneously play a connected MIDI
keyboard and talk into the microphone (if another input device
is being used such as a CD player, then ensure this is playing).
The resulting sound will have a Robot or talky like quality to it.
