WORKING WITH THE FILTER
You could activate the Filter Setup function directly by keying in 13. However, let’s
investigate another way to select the Filter function. Move the data slider to catalog the
various Dynamic Processing functions. When the display shows function 13, Filter
Setup, press ENTER.
CHANGING FILTER CUTOFF FREQUENCY
1. Refer to DYNAMIC PROCESSING 13. The display should look like the one in Step 1
of DYNAMIC PROCESSING 13.
2. Play with the cursor buttons (the left and right arrow buttons directly below the
display). Note how you can move the cursor under the various parameters to be
adjusted. For now, move the cursor under Fc.
3. Vary the data slider. Note how the numbers under Fc change. Lower numbers mean
a lower filter cutoff frequency (less high frequencies). Higher numbers mean a higher
filter cutoff frequency (more high frequencies). Observe how only the notes within the
current voice are affected by the slider setting.
Note: You must re-trigger a note to hear any changes. Holding down a note and playing
the slider will not change the sound; you must play a note after changing the slider to
hear the results of changing the slider. This is true when making any changes to the
sound, not just while you’re in the Filter function or the Dynamic Processing module.
By the way, now might be a good time to mention that although we are changing the
sounds in the bank, the sounds on the disk remain unchanged. This is because we
haven’t saved the bank to disk. Thus, you can fool around with the bank sounds as much
as you want without having to worry about altering the original sounds on the disk.
CHANGING FILTER Q
1. Move the cursor under Q on the display. Vary the slider to change the sharpness of
the sound; higher numbers give a sharper sound. Again, this affects only the range of
notes covered by the current voice. Leave the Q at about 90 and proceed.
2. Move the cursor back to Fc and vary the data slider. Note how this produces a sort
of wa-wa effect (remember, you have to re-trigger the key to hear the results of changing
the Q).
3. Now set Fc and Q to about 50. The range of notes covered by the current voice should
sound muted.
CHANGING THE FILTER CUTOFF ENVELOPE
1. Let’s investigate the effects of envelope control over the filtered sound. Move the
cursor under Env and use the slider to set a value of +40. This allows the envelope to
control the filter cutoff frequency. (See DYNAMIC PROCESSING 14.)
