PITCH FORK®+

POLYPHONIC PITCH-SHIFTER/HARMONY PEDAL

Congratulations on your purchase of the Electro-Harmonix PITCH

FORK®+, a fully featured polyphonic pitch-shifter/harmony pedal. The
PITCH FORK®+ has two independent pitch shifting engines each capable

of transposing over a +/- 3 octave range and detuning +/- 99 cents. Both
shift voices have their own volume control and a third for a dedicated DRY
level control. There are two output jacks MAIN and AUX. The AUX output
offers multiple routing options. In addition to a standard bypass
footswitch, there is a second footswitch, USER, which can be assigned to
a host of tasks. An input for an expression pedal or control voltage can be

assigned to many of the pedal’s parameters. There is an external foot-

controller input for hands-free control and a large easy to read display.
The PITCH FORK®+ has 100 slots for storing and recalling presets. Ten
factory presets are pre-loaded to help you get familiar with some of the
pedal’s incredible capabilities.

WARNING: Your PITCH FORK®+ comes equipped with an Electro-Harmonix 9.6VDC /
200mA power supply. The PITCH FORK®+ requires 120mA at 9VDC with a center
negative plug. Using the wrong adaptor or a plug with the wrong polarity may damage
your PITCH FORK®+ and void the warranty.

QUICK START GUIDE

Plugging in the PITCH FORK®+

1. Connect the EHX9.6DC Power Adapter into the 9V jack at the top

of the pedal. Plug the AC Adapter into an AC outlet.

2. Connect your guitar or other instrument to the INPUT jack using

a standard 1/4” instrument cable. Connect the MAIN OUTPUT

jack to your amp with another standard 1/4” instrument cable.

3. If using AUX, also connect the AUX OUTPUT jack to an additional

amp using another standard 1/4” instrument cable.

4. If using an expression pedal, such as the Electro-Harmonix

Expression, connect to the EXP jack with a TRS Cable.

5. If using an external three-button foot controller, such as the

Electro-Harmonix Triple Foot Controller, connect to the EXT jack
with a TRS cable.

Loading a Factory Preset

1. Press the PRESET mode button.

2. Turn the VALUE knob to scroll through factory presets

1-10

.

3. Press VALUE to load the selected blinking preset.

Creating a User Preset

1. Press the PRESET mode button.

2. Turn the VALUE knob counterclockwise to scroll down to

LIVE:

- LIVE is a template that can be used for creating a preset.

- LIVE settings can be saved to a preset slot to recall after a

power cycle.

3. Press VALUE to load LIVE.

4. Press the SHIFT 1 button then turn VALUE to adjust the

semitone setting for SHIFT 1.

5. Press the SHIFT 2 button then turn VALUE to adjust the

semitone setting for SHIFT 2.

6. Adjust DRY, SHIFT 1, and SHIFT 2 volume knobs to create the

desired mix.

7. Press the PRESET button and turn the VALUE encoder to select

an empty preset slot. An empty preset slot will not have a dot in
the lower right corner like the factory presets. Slots 11-100, by
default, are blank from the factory.

8. Press and hold VALUE for two seconds to initiate the saving

process. The saving process is complete when the PRESET LED
stops blinking.

CONNECTIONS

INPUT Jack – Audio input with an impedance of 2.2MΩ.

MAIN OUTPUT Jack – Main audio output with an impedance of 470Ω.

AUX OUTPUT Jack – Auxiliary audio output with an impedance of 470Ω.

EXP Jack – Expression pedal or control voltage (CV) input. The PITCH

FORK®+ allows for an expression pedal to be assigned to a number of
different parameters. See EXP Mode section for more details.

Expression input jack accepts a TRS expression pedal connector or a Tip­Sleeve 0-5V control voltage input. The expression pedal should ideally use
a 10k potentiometer with linear taper. It must have the wiper connected
to TIP and toe-down connected to RING. Pedals made by some
manufacturers do not conform to this convention and would need a special
cable to swap RING and TIP. Some suggested Expression Pedals: EHX
Expression Pedal, EHX Dual Expression, M-Audio® EX-P, Moog® EP-2 &
EP-3, Roland® EV-5 or Boss® FV-500L.

EXT JACK – TRS input for connecting a generic external foot-controller
such as the EHX Triple Foot Controller or Digitech® FS3X. A foot-controller
has three footswitches: MODE (Tip), UP (Ring) and DOWN (Tip+Ring).
These can be used for changing modes, entering/exiting sub-menus,
loading presets, and scrolling parameter values. Saving presets cannot be
done using an external foot-controller. See the EXT section for more
details.

9V Power Jack – Power input for the EHX 9.6DC 200mA power adapter.
The PITCH FORK®+ uses a 2.1mm center-negative barrel plug and
requires a current rating of at least 120mA at 9VDC.

CONTROLS & DISPLAY

DRY Knob – Controls the volume level of the DRY signal.

SHIFT 1 Knob – Controls the effect volume level of SHIFT 1.

SHIFT 2 Knob – Controls the effect volume level of SHIFT 2.

VALUE Knob – VALUE is a rotary encoder that can rotate continuously in

either direction, and be pushed like a button. VALUE will adjust the
selected mode parameter, enter sub-menus, or save presets to memory.
A press of VALUE enters sub-menus when applicable. Holding VALUE when
in PRESET mode saves a preset.

4-Character Display – The 4-character display shows the current
parameter value or menu setting for the selected mode. The display shows
which option is selected within a mode menu or sub-menu.

When there is a dot in the lower right corner of the display, for example

“

FREQ.

”, this signifies there is a sub-menu that can be entered. Enter a
sub-menu by pressing VALUE or a double-tap of the MODE (Tip) FSW on
an external foot-controller.

BYPASS Footswitch and LED – The BYPASS footswitch toggles
between effect on and buffered bypass. In latch mode, each press and
release of the footswitch toggles between effect and bypass modes. In
Momentary mode, when the footswitch is held down, the glissando effect
is on, when the footswitch is released, the PITCH FORK®+ enters bypass.
The status LED lights when in effect mode or when glissando is active.

USER Footswitch and LED – The USER footswitch’s function is
programmable when the USER mode button is selected. The USER
footswitch works independently from the BYPASS footswitch and has its
own status LED. When the LED is lit, an effect or feature is enabled. When
the USER footswitch LED is off, then the effect or feature is disabled or
not in use.

OVERVIEW OF MODES

The PITCH FORK®+ has eight control modes that are accessed by pressing
one of the eight illuminated buttons. The mode buttons can be used to
exit, go back to previous sub-menus, or back to the main mode menu.
Selecting a different mode button resets the previously selected mode to
its main menu and brings you to the newly pressed mode.

AUX – AUX mode selects which channel is sent to the AUX output jack.
The AUX menu can also select if and how the BYPASS footswitch will affect
the AUX output.

SHIFT 1 & SHIFT 2 – The SHIFT modes select the amount that each
shift engine will transpose the input signal. Each SHIFT mode can be set
to semitones or octaves covering a total range of +/- 3 octaves. Detuning
is also possible in either SHIFT mode.

EXP – EXP mode sets how the expression pedal or control voltage signal
is routed within each of the three sub-menus: FREQ, GLIS, and VOL.
These sub-menus will allow control over pitch, glissando (glide) rate, and
volume for both SHIFT voices and DRY.

USER – USER mode programs the function of the USER footswitch. The
user programmable footswitch can be assigned to control different
parameters or augment features.

X-MOD – X-MOD mode accesses the cross-modulation amount and
SHIFT2+DETUNE2 settings. Cross modulation can be used to create ring
modulation and FM type of effects, while SHIFT2+DETUNE2 adds the
detune amount from SHIFT 2 to its selected SHIFT value.

PRESET – PRESET mode manages loading and saving presets.

LATCH – The LATCH mode controls how the BYPASS footswitch operates.

As on the original Pitch Fork®, the BYPASS footswitch can be set to either
latching or momentary mode.
