Source Audio Soundlbox Tri-Mod Wah - Manual (Page 2)

FEATURES
The Soundblox Tri-Mod Wah is a new
type of “Auto-Wah” or “Envelope Fil-
ter” effect. The unit features multiple
filter types ranging from classic to
modern and beyond. Each filter type
can be controlled by an envelope
follower or an
LFO . An envelope fol-
lower is an algorithm that responds
to the amplitude (or volume) of the
incoming signal and creates a control
signal based on the input level. This
control signal is used to “move” or
modulate the filter to create a wah-
like effect. In addition to controlling
the filters with the envelope follower,
the filters can also be driven with an
LFO (Low Frequency Oscillator). LFO s
are most commonly used in effects
like phasers, flangers, and choruses.
The Tri-Mod Wah allows you to use
a variable
LFO to drive the filters for
a different take on the filter sounds.
Finally, the filter effects can also be
controlled by a Hot Hand Motion Sen-
sor. Either a wired or wireless sensor
can be plugged into the sensor input
on the back panel. When a sensor
is plugged in, the
LFO and envelope
follower are disengaged and the unit
goes into “Hot Hand Mode” and the
controls take on slightly different
functions. Also, the calibrate feature
is intended for use with the “Hot
Hand Mode” only. The Tri-Mod name
comes from the fact that there are
three distinct modulation sources for
controlling the filter effects: Enve-
lope,
LFO , or Hot Hand.
HOT HAND
READY
While the primary function of the
Tri-Mod Wah is as a standalone effect
pedal you also have the option of ex-
ploring some additional functions by
plugging in a Hot Hand sensor. When
a sensor is plugged in the envelope
and
LFO modes are disabled and the
unit goes into Hot Hand mode. In
Hot Hand mode, the controls take on
some secondary functions. These are
shown by the white text beneath main
label of the knobs.
Hot Hand Basics
The Hot Hand motion sensors are
sold separately and come in either
wired or wireless versions. Both
will work with the Tri-Mod Wah.
Additionally, the
SENSOR IN jack will
be compatible with any future Source
Audio sensors.
The Hot Hand ring contains an accel-
erometer that responds to accelera-
tion and is not based on any type of
proximity to the guitar. By moving
your hand or by changing the posi-
tion of your hand you can modulate
the effect. For a good description
of Hot Hand Theory, download the
Hot Hand Motion Controlled Wah
Filters manual. It is available at www.
sourceaudio.net. Keep in mind that
the Tri-Mod Wah can only use the
x-axis of the ring sensor.
USE WITH
HOT HAND
Depth
In Hot Hand Mode the depth knob
controls how much the filter will
move depending on the motion of the
sensor. Alternatively this can be
thought of as a gain control for the
Hot Hand sensor signal. To the right
of the ‘0’ position (the ‘+’ region), the
filter will move from low to high with
greater range as you turn the knob
further to the right. To the left of the
‘0’ position (the ‘-’ region) the filter
will move from high to low with in-
creased range as you turn the knob to
the left. This is basically the same as
the ‘invert’ feature on the original Hot
Hand Motion Controlled Wah Filters.
Motion Control
The
SPEED control becomes the MO-
TION control in Hot Hand mode and is
used to smooth out the input from the
sensor by filtering out fast changes in
the signals. The amount of smoothing
is controlled by the knob. Turning the
knob towards
FLAIL provides the most
amount of smoothing and the effect
will now only react to large, slow
motions of the sensor. This is useful
when you only want the effect to
respond to large, deliberate motions.
Turning the knob all the way to
PICK
sets the smoothing at a minimum.
This means that fast changes in the
sensor signal will be applied to the
effect. The motions created from nor-
mal picking will be enough to move
the filter. This may cause the sound
to be too “jittery”, in which case, turn
the knob towards
STRUM and FLAIL to
get the desired response. The STRUM
setting is a nice compromise that
allows some moderately fast motions
through without being too jittery.
Calibration
The Tri-Mod Wah has a calibration
feature which is only used in Hot Hand
mode. However, calibration is not
required before use. The calibration
feature allows you to set the midpoint
of the filter sweep for any position of
your hand. Depending on your playing
style, you may find it useful to try
some different calibration positions.
The most common use of calibration
is setting your resting hand position
on the guitar to be the midpoint of the
filter sweep. Calibration can also be
useful if you are putting the sensor
on a headband or other alternate
locations.
To perform a calibration
• Turn the EFFECT knob to the
CALIBRATE position.
• Hold the sensor in the desired
position.
• While holding the sensor steady,
press the ON/OFF footswitch and
wait for 1 second.
• Turn the EFFECT knob away from
calibrate to use your new calibra-
tion setting. Note: Calibration set-
tings will be saved between power
cycles.
• If you have trouble with calibration
and need to get back to the default
setting, place the sensor on a flat,
level surface with the blue
LED
facing down and run the calibration
procedure again.
