Source Audio Hot Hand Phaser/Flanger - Manual (Page 8)

LFO
Phasers and flangers are typically controlled by an automatically slowly vary-
ing signal called a Low Frequency Oscillator
(LFO) . An LFO may be selected as
the modulation source. In addition to the MOTION/SPEED knob, the speed may
be controlled by an external expression pedal, or by the Hot Hand. The LFO
produces a sine wave to modulate the Flanger, and a triangle wave for the
Phaser. The
LFO may also be switched to become an audio frequency oscilla-
tor. It can provide ring-modulated sorts of sounds. This option is only for the
seriously crazed.
Sequencer
A sequencer is a device, more commonly associated with synthesizers, that
puts out a repeating series of control levels. While not often found on phasers
and flangers, it is quite an interesting sound. The
LFO may be switched into
driving such a sequencer, by turning on the INVERT switch from the MOTION/
SPEED knob. 9 different sequence lengths are available, and for each of these
lengths there are 9 different prestored patterns that may be chosen.
A transition time may be set that determines how rapidly the control
signal moves from one level to the next when the sequencer moves on to
the next step.
Instead of putting out a repeating series of levels, the sequencer may be
switched into chosing a random value each time the next step is taken.
See page 31 for a full description of the sequencer control parameters.
Envelope follower
An envelope follower takes the incoming guitar signal and generates a con-
trol signal which gets larger for louder guitar signals. This control signal may
be used as a modulation source.
The attack rate, or the time it takes for the control signal to rise up after a
new note has been struck, may be adjusted. Stacato playing, with a very brief
period of silence between notes, will give the most dramatic results, by allow-
ing the control signal to be reset back to zero during the silence.
Calibration (optional)
Your use of Hot Hand will benefit from the unit being calibrated to your play-
ing position and style. In effect, you are telling the control box where your
hand is when it is centered over the strings. Calibration is recommended
when using for the first time or when your playing position changes due to
guitar strap changes or when moving from standing to sitting. If you do not
calibrate, the “zero” or center point of the Hot Hand signal may not match the
natural resting position of your hand.
To calibrate, turn the EFFECT knob to the CALIBRATE position and hold your
strumming hand in its normal playing position over the strings. Then, tap the
ON/OFF pedal once. The
ON/OFF LED will blink for a few seconds. When the
LED is off, you are calibrated and ready to go. Please note that the effect will
be muted when the selector is in the CALIBRATE position.
Calibration data is remembered until another calibration is performed, even
when the unit is turned off.
ADVANCED USER NOTES
1) The calibration “zero” point does not necessarily need to be in the middle of your arm stroke.
By setting the zero point higher or lower it is possible to span a different range of the effect.
Also, calibration may be required if the Hot Hand sensor is mounted to some other part of your
body (head, foot, etc.)
2) One calibration setting is typically used across all presets. However, it may desirable to create
a different calibration setting for each preset. When the function selector is turned to CALIBRATE
all the preset LEDs will be lit, indicating that you will be recalibrating all the presets. If, before de-
pressing the ON/OFF pedal, one hits the SELECT pedal, the light from the last preset selected turns
on. If only one preset LED is lit, then only that preset gets the new calibration data. The remaining
presets are unaffected, even if the last calibration applied to all presets. Pressing SELECT again
toggles back to selecting all presets.
Expression input
If a modulation control signal is needed that is more appropriately generated
by a controller like a wah pedal, an external expression pedal may be plugged
into the
EXPRESSION IN jack.
