ENVELOPE

has been selected as the

MOD SOURCE

, the

MOTION/SPEED

knob sets how fast the envelope signal rises and falls in response to the
guitar input signal. Counterclockwise is faster, and clockwise is slower. The

INVERT

switch ﬂips over the direction of modulation sweep by the envelope.

If the

LFO

has been selected as the

MOD SOURCE

, the

MOTION/SPEED

knob

becomes the rate control for the

LFO

. Faster rates are in the counterclockwise

direction. (Note that regardless of the speciﬁc modulation source selected,
things happen faster with the

MOTION/SPEED

knob set toward the counter-

clockwise direction.) The range of the

LFO

is from

Hz to

Hz (or a period

of ﬁve seconds down to one-tenth of a second.)

If an expression pedal is plugged in to the

EXPRESSION

In jack, it will modify

the

LFO

speed as set by the

MOTION/SPEED

control. When the pedal is in the

full down position, all

LFO

rates are divided by a factor of

2.88

, while a full up

position multiplies all rates by

2.88

. (Use of an expression pedal thus increas-

es the range of

LFO

speeds.) The fastest speeds can produce something of

a ring modulated sound.

There is a Back Page parameter that may be set to permit use of the Hot
Hand for controlling the

LFO

speed, instead of the pedal. This may be of

marginal utility if the sensor ring is worn on the picking hand, but nice results
can be obtained with the ring worn on the player’s head or on the guitar body.

The

INVERT

switch turns the

LFO

into a “preset” sequencer. A variety of pat-

terns, of different lengths, are pre-stored. The Back Page parameters may
be used to choose the pattern and length. Also available is the transition time
from one step to another. Finally, instead of a repeating sequence of levels,
a random value may be chosen each time the level changes.

When using the sequencer, there is one step per

LFO

period. The slowest

LFO

rates for normal

LFO

mode become too slow to be useful with the sequencer,

and so the slowest

LFO

speed has been increased to

Hz, while the fastest

rate remains the same at

Hz. Control by an expression pedal is still by the

same factors.

MOTION/SPEED Knob/INVERT

If Hot Hand has been selected as the

MOD SOURCE

, the

MOTION/SPEED

knob

essentially determines how sensitive the Hot Hand is to rapid motion of
the sensor. Setting this knob towards “Pick” will make the Hot Hand more
sensitive so that even the quickest motions will be picked up. Setting it to
near “Strum” is best for strumming, and “Flail” will reduce the sensitivity so
that only more dramatic (slower) motions will produce a noticeable effect.
Alternatively, the motion knob can be thought of as setting the amount of
“smoothing” of the Hot Hand signal. “Pick” having the least smoothing, while
“Flail” has the most.

The “Pick” position will pass more of the very rapid transient motion caused
by the jar of hitting a string with a pick to go into the ﬁnal control signal. It
can produce something like an envelope follower type of sound. As the knob
is rotated clockwise, less of these quick transients are passed, and things
seem less jittery. You really have to do some experimenting with this control
in order to get a feel for how to adjust it to match your playing style and the
sound you are trying to get.

Turning the

MOTION/SPEED

knob all the way around past the six o’clock posi-

tion causes the Hot Hand to invert its axis—up is down and down is up. When
the

INVERT

light is off, the product is in normal mode, while on indicates

inversion. For the Phaser, with normal mode, the hand up position moves
the frequency response notches to higher frequencies, and with invert moves
them to lower frequencies. For the Flanger, normal mode and hand up posi-
tion generally makes the delay lines longer, and thus increases the number
of frequency response notches present.
