The
Pitch Fork transposes an instrument's pitch over a +/- three-octave
range and features three modes which allow the pitch to be transposed
up, down or both, simultaneously. The pitch shift amount can be set to a
fixed interval or continuously varied by an expression pedal or control
voltage.
The controls are straightforward and intuitive. An
11-position Shift switch selects the maximum transposition interval
ranging from D (Detune), a shift of 17 cents, through Minor 2nd, Major
2nd, Major 3rd, Perfect 4th, Perfect 5th, Major 6th, Minor 7th, 1
Octave, 2 Octaves and 3 Octaves. A three-position toggle switch controls
whether the pitch is transposed up, down or both. In Dual mode, two
pitch-shifted signals are output. One follows the shift knob as if in
the Up position while the other creates a harmony. Dual Mode settings
include M3 up + P5 up, P5 up + 1 Oct down, 1 Oct up + 1 Oct down and
many others. A Blend knob controls the mix of the dry signal and the
effected signal, and an EXP jack enables the player to control pitch and
glissando with an expression pedal.
The Latch button selects
Latch or Momentary mode which affects how the footswitch and EXP input
behave. In Latch mode, the footswitch toggles between effect on and
buffered bypass each time it's pressed and the EXP input continuously
varies pitch. In Momentary mode the effect is only on while the
footswitch is depressed and when it is released the Pitch Fork goes into
bypass.
In Latch mode the EXP input controls pitch shift amount,
ranging from unity to the interval set by the Shift knob, and pitch
varies continuously throughout the expression pedal's range. In
Momentary mode the EXP input controls glissando rate for the Pitch
Fork's footswitch. When the bypass footswitch is pressed, the Pitch Fork
jumps from bypass to the interval set by the Shift knob. The amount of
time it takes to reach that new note is the glissando rate. When the
footswitch is released the pitch will return to unity at the same rate.
That glissando time can vary between four milliseconds to two seconds
depending on the heel/toe position of the expression pedal. The default
glissando rate is 60 milliseconds when nothing is plugged into the EXP
input.
The Pitch Fork comes equipped with an EHX 9.6DC-200mA power supply and also runs on a 9-volt battery.
