[ RESONANCE] knob
Resonance emphasizes the sound in the region of the  lter
cuto frequency.
Increasing the resonance setting will increase this em-
phasis, producing a distinctive sound that is characteristic
of synthesizers. If you want to accentuate the resonance
e ect, it’s a good idea to lower the cuto slightly.

Turning the knob toward the right will emphasize the
sound in the region of the cuto frequency, producing a
more distinctive sound.
Turning the knob toward the left will remove the emphasis
from the sound in the region of the cuto frequency,
producing a milder sound.
* If “BYPASS” is selected as the  lter mode, turning the
[RESONANCE] knob will not a ect the sound.
NOTE
In response to demands by pro sound designers for
tonechanging capabilities, the GAIA SH-01 permits a wide
variety of resonance settings. Because of this, raising the
resonance level too much results in extremely high output
levels in speci c frequency ranges. Be careful to keep the
volume settings down when creating sounds in order to
prevent overloading audio playback equipment.
[ KEY FOLLOW] knob
Here’s how you can make the  lter cuto frequency to vary
according to the key you play.
Turning the knob toward the right (maximum value is
+100) will make the cuto frequency rise as you play
toward the right side of the keyboard, and fall as you play
toward the left side of the keyboard.
Turning the knob toward the left (maximum value is -100)
will make the cuto frequency fall as you play toward the
right side of the keyboard, and rise as you play toward the
left side of the keyboard.
If the knob is in the center position (0), the cuto
frequency will not be a ected by the notes you play.
* If “BYPASS” is selected as the  lter mode, changing this
setting will not a ect the sound.

FILTER ENV (Filter envelope)
On instruments such as a piano, the beginning of each
note has a bright sound, which gradually becomes darker
(more mellow) as the note decays.
The  lter envelope lets you simulate this and many other
kinds of time-varying changes in brightness.
