06: How to select and control the effects

Preset Selection

Make sure effects are engaged by checking the ON/OFF light. Toggle the ON/OFF pedal to turn it on, if necessary.

Select any of the four presets by using the them. Note which of the

MOD SOURCE lights are on at the top of the EFFECT

knob. These select what will be sweeping the effect. If the on, moving the

HOT HAND will not make any difference.

Editing

• Use the EFFECT knob to select any of the 7 phasers or 7 ﬂangers.

• Hold down the SELECT pedal, and turn the EFFECT knob. It will now change

the MOD SOURCE selection instead of making an effect selection.

• Use the DEPTH control to select the amount of modulation depth (sweep)

applied to the effect.

• Use the MOTION/SPEED control to select how fast the modulation source var-

ies. It determines how much the Hot Hand responds to rapid motion; it sets the LFO speed; and it controls how quickly the ENVELOPE tracks the levels of the guitar signal.

• Turn the MOTION/SPEED knob such that the LED indicator light moves across

the bottom-most part of the range. This will change the state of the switch. If

INVERT is on, both the HOT HAND and ENVELOPE direction of sweep

will be reversed.

• When LFO is selected as the MOD SOURCE, turning on INVERT will select SEQ

as the modulation source instead of the

LFO. Sequencer patterns will then be

used to sweep the effect.

• Hold down the SELECT pedal, and adjust FREQUENCY range for the phasers,

and DELAY time for the ﬂangers with the DEPTH knob.

05 : Calibration (optional)

Calibration is recommended, but not required. See page 11 for additional information.

Calibration is easy. Just turn the position and hold your strumming hand in its normal playing position over the strings. Your hand should be held relatively still. Then, tap the pedal once. The

ON/OFF LED will blink for a few seconds. When the LED is off,

you are calibrated and ready to go. Turn the Effect Selector knob away from the CALIBRATE position to select an effect.

The Hot Hand Concept

The Hot Hand provides a new way to control effects. It is no longer necessary to stand over a pedal board. The movement of the picking hand becomes an expression pedal. The control follows the rhythm of the music without con scious effort. It is also possible to move the hand much quicker than a pedal can be moved. The potential for additional showmanship in live performance must not be overlooked.

Some other possible places to put the Hot Hand sensor besides on a ﬁnger of the picking hand include shoes, a headband, the guitar headstock, your drum mer’s hand, your singer’s hand…

OK, maybe the singer isn’t such a good idea.

The Controls

The Hot Hand Control Box is where all of the effects are created and controlled. The product contains Some sounds are classics, others are new, and all have been carefully modeled and created by real musicians. And by using the presets, you can switch between

FOUR of those sounds without ever bending down to tweak

a knob on stage.

Note that the Hot Hand control box uses rotary encoder knobs and rings. This allows you not only see the knob locations in low light situations, but you can also jump from one preset to the next and see the setting of each knob quickly.

The product also gives you one control over each effect:

the Phaser, which shifts the range of the Phaser sweep, or Flanger, which scales all the delay times. This control will greatly change the sound of the effects. It is independent of the modulation source selection.

In addition to using the Hot Hand to translate hand motion into a signal to sweep the effects, other modulation sources that may be used are a Low Frequency Oscillator

(LFO) that provides a periodic back and forth sweep,

a Sequencer that generates a repeating series of control levels, and an Envelope Follower, which responds to the level of the guitar input signal. The MOTION/SPEED control adjusts how fast all of these control sources act, and the DEPTH control adjusts the range of the effect sweep.

There are three other features related to external “expression” control. First, the EXPRESSION IN allows you to control the effects in the Control Box with an external expression pedal. The effect modulation signal and use it to control other effects boxes that have an Expression Input feature. Finally, the Hot Hand signal to other Source Audio Hot Hand products and control them with a single motion sensor.

Hot Hand

While it is certainly possible to use Hot Hand without much technical background, a few words about how it works will allow you to quickly understand how hand position and hand motion impact the sound. The Hot Hand sensor senses acceleration. This means that both hand position and hand motion will cause the Hot Hand to react and send signals to the control box.

Hand Position

Since gravity is an acceleration, the Hot Hand is always measuring the pull of the Earth’s gravitational force. To illustrate this, try strumming a chord and pointing your hand with the sensor attached straight at the ground. By bending your arm at the elbow, slowly move your forearm up until your hand is pointing at the ceiling. You should hear the effect sweep following the posi tion of your arm. When the same gesture will sweep the effect in the opposite direction. You don’t need to move your entire arm to accomplish this. The same effect can be achieved changing your hand position by bending at the wrist or by leaning back and moving your hand and the guitar together. Hand position can range from subtle movement to the not so subtle. If subtlety is not your thing, dramatic motions will open the door for showmanship as your hand shapes the sounds from your guitar. We must point out that the Hot Hand will respond differently in Outer Space!

When you are using hand position and larger hand or arm motions to control the Hot Hand, we recommend turning the will prevent the Hot Hand from responding to small variations and sounding too “jittery”.

INVERT light is on, the opposite will be true and the

MOTION knob towards FLAIL. This

Hand Motion

In addition to measuring gravitational force, the sensor also measures movement. The more the hand moves, the more the signal will change. To illustrate this, strum a chord and shake your hand quickly. You should hear the ﬁlter sweep back and forth following your hand motion. Experiment with moving your hand in different directions and at different speeds to ﬁnd the method that works best for you. Use the

MOTION/SPEED knob to control how

quickly an effect will respond to your hand motion. In the most sensitive posi tion (PICK) the Hot Hand will detect even the slightest motion of the picking hand. In the STRUM position, the Hot Hand will react more slowly. Try strumming some chords normally and listen to how the Hot Hand reacts.

Your use of Hot Hand will beneﬁt from the unit being calibrated to your playing 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

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.

LFO

Phasers and ﬂangers are typically controlled by an automatically slowly varying signal called a Low Frequency Oscillator the modulation source. In addition to the be controlled by an external expression pedal, or by the Hot Hand. 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 driving such a sequencer, by turning on the

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.

LFO may be switched into

Envelope follower

An envelope follower takes the incoming guitar signal and generates a control 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

does not invoke the calibration function (although it does temporarily mute the audio.)

If the Phaser effect has been selected, the FREQUENCY/DELAY knob acts as an offset for the Phaser’s frequency response characteristic. Counterclockwise values will position the typical Phaser notches at lower frequencies than will clockwise values.

If the Flanger effect is selected, the the delay times used in the Flanger together. Counterclockwise settings give short delays, which will have fewer notches in the Flanger frequency response. Clockwise settings will give longer delays, producing a more complex sound.

STRUM

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.

If 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 clockwise direction.) The range of the

MOTION/SPEED knob set toward the counter-

LFO is from .2 Hz to 10 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 position multiplies all rates by es the range of

LFO rates are divided by a factor of 2.88, while a full up

2.88. (Use of an expression pedal thus increas-

LFO speeds.) The fastest speeds can produce something of

a ring modulated sound.

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.

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 patterns, 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 rates for normal and so the slowest rate remains the same at

Technical Note: The pedal needs to have a linear taper potentiometer, from 10K to 100K, with one side connected to ring, and the other to ground, and the wiper connected to the tip of the TRS ¼inch connector. We have found that the Moog and M Audio EXP pedals work well. Audio taper pots, as commonly found in volume control pedals, will not give good results.

Very Technical Note: An external control voltage source, such as from an analog synthesizer, may be connected to the EXPRESSION IN jack. A mono ¼-inch cable may be used for this application. Do not allow the input voltage to go negative with respect to ground.

Effect Types

Following are descriptions of the different effect types we programmed into the Hot Hand box. Note that each sound interacts differently with both the Hot Hand hand motions, or other modulation sources, as well as the settings on the

DEPTH, FREQUENCY/DELAY and MOTION/SPEED knobs. It is suggested that

you experiment a bit to ﬁnd just the right sound for different playing styles.

Phasers

The input signal goes into a number of phase shift sections. Each section has a control which determines the frequency around which the resultant phase shift makes a smooth transition from output of the last phase shifter is combined with the input. Any frequencies at which the shifted signal is an odd multiple of will undergo total cancellation, producing a notch in the spectrum. Some of the shifted signal may be fed back to the phase shift chain. Frequencies which are a multiple of

360 degrees from the input will be boosted, causing

a peak in the spectrum. This is called resonance.

0 degrees to -180 degrees. The

Flangers

A Flanger works very much like a Phaser, except that instead of using a chain of phase shifters, a delay line is used. The length of time a signal is delayed is controlled by the modulation. The sum of the delayed signal with the input signal produces notches at frequencies where there is cancellation. Feedback will introduce resonance peaks between the notches. At short settings of the

DELAY time control, there will be fewer notches in the Flanger’s frequency

response than at long delays.

vibrato. There are some small resonance peaks, so that vibrato doesn’t sound too sterile and mechanical. Slow modulation will be nearly inaudible. Shorter

delay times will produce less of an effect than long delay times.

Order of Effects

A controversial subject, to be sure. But phasers and ﬂangers will give more dramatic results if there is more high frequency content to the sound being processed. A distortion box will do just that, if it is in front of the phaser or ﬂanger. Distortion following a phaser or ﬂanger, on the other hand, tends to ﬁll in the notches in the frequency spectrum and obscure the effect. Let your ears be your guide.

A compressor in front of this product will somewhat reduce the range of the envelope follower signal, since it will be reducing the loudness variations. Total, over-the-top mega-distortion before the effect can be a problem for the envelope follower, because it removes all of the dynamic range of the guitar signal, and tends to ﬁll in what would be silence between notes with hum and noise.

Back Page Features and Controls

We have tried to balance the conﬂicting requirements of ﬂexibility and simplicity in this unit. Thus, a number of parameters appear in what we call Back Page editing. These are parameters that, in general, will not need as frequent adjustments as the controls that are directly accessible from the front panel. (These parameters, along with the presets, may be restored to the factory settings through the Restore function.)

To get into this special editing mode, hold down the push and hold the SAVE button for 2 seconds. The unit will then stay in this editing mode without any controls being held down. The knobs will used to edit the parameters. To exit from this mode, turn the func tion selector to the Page editing mode is the lack of any lit

LEDs around the MOTION/SPEED knob.

Each preset has its own independent set of Back Page parameters. When entering the Back Page parameter editor, either all the preset lit, or only the one corresponding to the currently selected preset. Hitting the

SELECT pedal will toggle between these two states. Any changes made to any

particular parameter will be made to all presets if all the preset otherwise, the change will only be made to the current preset. Thus, it is easy to go in and change the Hot Hand axis selection for all presets, or to change the sequencer pattern for only one preset. Without exiting from the Back Page editor, you can make changes for all presets, and then some changes to only the current preset.

The EFFECT knob selects the parameter to be edited and the DEPTH knob displays the current value and allows adjustment. The displayed value of each parameter is taken from the stored value for the current preset. All changes are saved automatically as they are made, either to all the presets, or only the current preset. If no change is made with the is saved, even though all the preset

LEDs may be lit. Thus, you do not have to

worry about replacing all the parameters for all presets merely by scrolling through the parameters when all the preset

Input gain trim (Effect=Phaser 01)

This is a gain adjustment applied to the guitar signal immediately after A/D conversion. The possible values are

-8, -6, -4, -2, 0, 2, 4, 6, and 8 dB. Positive

values may be helpful for low level signals. If the input signal is particularly hot, some attenuation may be required in order that the outputs of some of the effects with the most resonance does not clip. This may also be used as a per-preset volume adjust.

Hot Hand gain trim(Effect=Phaser 03)

This adjusts the gain multiplier applied to the Hot Hand signals relative to the zero point from calibration. The lowest gain is default of

Back Page Features and Controls | 2726 | Back Page Features and Controls

Hot Hand x and y-axis interchange (Effect=Phaser 05)

The Hot Hand sensor uses a two axis accelerometer. By default, the Hot Hand senses acceleration along the x-axis. The x-axis runs parallel to your arm and the long dimension of the sensor ring. The y-axis is perpendicular to x, while still being in the plane of an outstretched hand wearing the ring. We gener ally ﬁnd that the x-axis gives better control than the y-axis, but feel free to experiment, especially if your playing technique is somewhat unconventional. (Lefties—no, you still want to use x, but the normal and inverted settings are effectively switched.)

Please note that if you are using the y-axis that you may need to re-calibrate with your hand and the sensor parallel to the ground (palm down). This will allow you to set a useful “zero” point for the y-axis.

Expression control output gain trim (Effect=Phaser 07)

This allows adjustment of the level of the signal on the EXPRESSION OUT jack. The default is position zero and

3.3VDC. The maximum output voltage is 4.5VDC. Note that greater

changes in signal can also be produced by faster motion of your hand. Higher gain will allow you to use slower motions to achieve the desired signal levels.

KNOCK control (Effect=Envelope)

This parameter enables the unit to be toggled between effect on and effect off by tapping the sensor wearing hand against a hard surface, such as the guitar. There is a threshold level, which may be adjusted as needed. Higher thresholds will need a harder tap to be recognized, but there will be less chance of an accidental trigger from normal hand motions. Somewhere in the middle of the range will generally be best. Note that this control may be used regardless of whether or not the Hot Hand is being used as a modula tion source.

Sequencer Controls

There are 9 patterns available for each of 9 length selections. The ﬁrst length selection is for a length of 3. It also includes the only possible length 2 pat tern, a square wave. Since there aren’t enough other length 3 patterns to ﬁll

out the entire list of 9 patterns, several length 6 patterns are also included. The other lengths, from 4 through 12 (excluding 11) are all consistent through each of their patterns. A brief description of the nature of the patterns is in the table below. For lengths 9, 10, and 12, the narrow pulse pattern (all steps at the lowest level, except for one at the highest) seemed pointless, and so a more complicated pattern was used.

Sequence/Random (Effect=Flanger 01)

This parameter determines whether the sequencer will cycle through the pre-stored sequence patterns, or use random values that don’t repeat. If random is selected, the pattern and length parameters are ignored.

Piggy-backing on this parameter is the ability to speed up the LFO by a factor of 100. This speed up applies even if the sequencer is not selected.
