Polyphonic Pitch Shifter

Welcome to the Electro-Harmonix Pico Pitch Fork, a com-
pact, polyphonic pitch-shifter/harmony pedal. The Pitch
Fork transposes the pitch of your instrument over a range
of up to +/- 3 octaves. Three pitch-shifting modes allow the
pitch to be transposed up, down or both simultaneously.
The footswitch can operate with two different modes:
Latching and Momentary. Momentary allows rapid tog-
gling between effect and bypass for quick blasts of pitch
bending. The SWEEP knob allows you to dial in the pitch
sweep speed when switching between bypass and effect,
while the BLEND knob allows for the perfect mix of your
dry and transposed signals.
Operating Instructions
Insert the output plug from the supplied 9VDC AC adapter
into the power jack at the top of the Pico Pitch Fork. The
unit must be powered to pass signal, even in bypass. The
pedal features buffered analog bypass or digital bypass
depending on settings. Connect an instrument cable from
your instrument to the Input jack. Connect an instrument
cable between the Output jack and a suitable amplifier.
Click the footswitch to engage the Pico Pitch Fork and light
the LED.

Power Suppy Requirements: Voltage: 9VDC Current: 100mA Polarity: Center-Negative
This device comes equipped with an Electro-Harmonix 9.6DC-200 power supply. Use of the wrong adapter or a
plug with the wrong polarity may damage the device and void the warranty. Do not exceed 10.5VDC on the power
plug. Power supplies rated for less than 100mA may cause the device to act unreliably.

Controls & Jacks
1. VOL Controls the output volume.
2. BLEND Adjusts the output mix from 100% dry
to 100% wet.
3. SWEEP Controls pitch bend sweep time, when
toggling between bypass and effect and back.
The higher the setting, the longer the sweep time
which maxes out at 4 seconds. Set SWEEP to min-
imum to bypass pitch sweep.
4. SHIFT Controls the pitch shift interval relative to
the input signal. Whether the pitch is shifted up or
down depends on the state of the MODE LED. The
intervals are incremented as you move the knob from
minimum to maximum. The LED flashes briefly each
time a new interval is selected. The intervals are:
1 - DETUNE
2 - MINOR SECOND
3 - MAJOR SECOND
4 - MAJOR THIRD
5 - PERFECT FOURTH
6 - PERFECT FIFTH
7 - MAJOR SIXTH
8 - ONE OCTAVE
9 - TWO OCTAVES
10 - THREE OCTAVES
5. MODE Button Press this button to choose your
pitch shift direction:
Red – PITCH UP
Green – PITCH DOWN
Orange – DUAL MODE
DUAL Mode In DUAL mode the Pitch Fork synthe-
sizes two different intervals simultaneously. The
intervals are incremented as you move the SHIFT
knob from minimum to maximum as follows:
1 - DETUNE
2 - DEEP DETUNE
3 - MAJOR SECOND UP + MAJOR SIXTH UP
4 - MAJOR THIRD UP + PERFECT FIFTH UP
5 - PERFECT FOURTH UP + PERFECT FIFTH DOWN
6 - PERFECT FIFTH UP + ONE OCTAVE DOWN
7 - MAJOR SIXTH UP + PERFECT FIFTH DOWN
8 - ONE OCTAVE UP + ONE OCTAVE DOWN
9 - TWO OCTAVES UP + ONE OCTAVE DOWN
10 - THREE OCTAVES UP + ONE OCTAVE DOWN
6. Footswitch and Status LED Footswitch engages
or bypasses the effect. The LED color indicates the
selected pitch mode. In bypass mode, the LED is off.
7. Input Jack Impedance: 2.2MΩ, Max In: +1.5 dBu
8. Output Jack Impedance: 680Ω, Max Out: +2.1 dBu
9. Power Jack Current draw: 100mA at 9.0VDC

Latch & Momentary Footswitch Selection
The footswitch toggles between effect and bypass with
two distinct methods of operation: Latch and Momen-
tary. In Latch, each press and release of the footswitch
toggles between effect and bypass. In Momentary, the
effect is active when the footswitch is held down and
bypassed when the footswitch is released.
Latch is selected by default from the factory. To change
to Momentary, do the following:
1. Press and hold the MODE button
2. After two seconds, the LED rapidly cycles through its
three colors.
3. Release the button; Momentary mode is now active.
4. Repeat this same procedure to change back to
Latch mode.
The footswitch setting is remembered through pow-
er-cycles so you can set it and forget it.
Bypass Modes & Selection
The Pitch Fork features three distinct bypass topologies:
Digital Bypass (Green) This is the default bypass
type. In this scenario your signal is fully digital even
in bypass. This bypass type allows for the smoothest
transitions between bypass and effect mode, which is
most evident when using pitch sweeps.
Analog Bypass (Orange) The bypass signal is analog
and buffered. Analog bypass gives you the purest,
least-colored sound in bypass mode.
Hybrid Bypass (Red) In this bypass type, when you
switch from effect to bypass, your bypass signal is
initially digital, but the pedal will seamlessly switch to
analog bypass when there’s a brief gap in your playing.
Hybrid Bypass allows for a smoother transition from
effect to bypass when using pitch sweeps, while allow-
ing your bypass signal to be analog the vast majority
of the time.
Digital bypass is selected by default from the factory.
To change the bypass topology, do the following:
1. Power down the Pico Pitch Fork.
2. Press and hold the footswitch.
3. While holding down the footswitch, apply power to
the unit.
4. Continue to hold down the footswitch. After about 2
seconds, the LED begins blinking rapidly.
5. Release the footswitch. The color of the blinking
LED represents the current bypass setting. Green is
digital, orange is Analog, and red is Hybrid.
6. To change the bypass setting, press and release the
MODE button. The LED color changes with each
press. When the LED color matches your desired
bypass mode, press and release the footswitch once.
The bypass mode setting is remembered through
power-cycles so you can set it and forget it.
