Electro-Harmonix

Notes: 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 4 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 9Volt battery.

The Intelligent Harmony Machine's Moment Mode lets you instantly change pitch by simply depressing the pedal's footswitch. The pitch shift is engaged as long as you hold down the F/S. There's also an option so you can apply a user-set sweep time between dry and effect. Choose instant pitch changes or control the time it takes for the Intelligent Harmony Machine to sweep up and down between the set interval and the dry signal!

EHX Founder, Mike Matthews said: "We designed the Intelligent Harmony Machine for the player who craves maximum power, but in a minimal footprint. You'll dig its sweet, musical tone and spotless tracking!"

*Diatonic harmony means notes within a specific key that relate to each other.

Compact harmony generating, pitch-shifting powerhouse
Impeccable tracking and superb musical tone
Two distinct modes: Intelligent Harmony and Polyphonic.
Intelligent Harmony Mode generates diatonic harmonies in a set key based on the single notes you play. Key Selector and #/- switches provide access to all 12 keys.
In Polyphonic Override Mode you can play single notes and chords. The IHM's 11-position Interval Selector switch lets you select the harmony.
In Momentary Mode the effect is only active when the footswitch is depressed. Choose from instant shifts or set the time it takes the signal to sweep up and down.
Mix control sets the mix between your dry and shifted signals. Dry output adds signal routing and control options and flexibility

Notes: Buzz. Beep and bloop. Get high on the lo-fi sounds of "old-school" games, toys and terminals!

The Mainframe provides sample rate reduction ranging from 48kHz to 110Hz. A little background... the sample rate is the number of times per second that a sample or snapshot of an analogue signal is taken. For example, CDs (remember them?) had a sample rate of 44.1kHz which means that the original analogue signal is sampled 44,100 times per second.

The sample rate defines the frequency range that can be reproduced while maintaining good fidelity. When the sample rate is reduced the quality of the audio is degraded and aliasing occurs. Aliasing means audible artifacts created when higher frequencies are sampled at an inadequate rate and the result is distortion. The Mainframe's sample rate range is wide enough to take you from sounds that are quite pristine to sounds that are unrecognizable when compared to the input signal.

It also provides bit crushing ranging from 24-bit to 1-bit. What does that mean? Bit crushing is bit depth reduction. Back to the CD example... CDs used a 16-bit bit depth meaning that each of its samples was represented by 16-bits of information. Higher bit depths can accurately represent a greater dynamic range while bit crushing increases the number of sampling errors and creatively degrades the sound to bring us back to those nasty "old school" sounds we love.

The Mainframe's selectable High/Low/Band-Pass filter lets the user shape the artifacts of the bit crushing and sample rate. Another very cool feature is its Sample Rate Tuning Mode where the pedal analyses your input signal in real-time and sets the sample rate to match the pitch of your signal, or a set interval above your signal. This allows you to set the sample rate to match the key of a song, or it will continually adjust the sample rate based on what you play!"

Notes: With 11 reverb types and a ton of "hidden" functionality, the Electro-Harmonix Oceans 11 reverb pedal could be your new go-to reverb pedal. You can tap into classic tones like hall, plate, and spring reverbs, including a brand-new spring reverb algorithm that sounds gloriously complex and rich - you can even double-tap the footswitch to "crash" the spring reverb. And you'll be able to cover a huge range of modern tones with a variety of modulated reverbs, shimmer reverb, reverse reverb, and more. A mode switch offers access to variations on many of the 11 reverb types. Complete with an infinite reverb mode for freeze-style effects, there is vast creative potential in the Electro-Harmonix Oceans 11 reverb pedal.

Reverb types:

Hall - rich and full sound of a grand concert hall
Spring - brand-new tube spring reverb emulation
Plate - lush and warm plate reverb
Reverse - each note fades in backwards
Echo - recirculates echoes through the plate reverb algorithm
Trem - hall reverb plus tremolo
Mod - modulated reverb
Dyna - swells, gates, and ducks in response to your playing dynamics
Auto-Inf - auto-infinite reverb, triggers a wash of reverb with each new note or strum
Shim - shimmer reverb with an octave-shifted wash that blooms behind your core tone
Poly - polyphonic reverb with two pitch shifts operating on your pre-reverb guitar tone

Notes: Expanded Freeze in a lowball-sized package!

Meeting between the original Freeze and Superego pedals is the Pico Deep Freeze Sound Retainer. With the ability to freeze a moment in sound, the Deep Freeze can act as a sustain pedal for holding chords and notes as backing for your playing or as a platform to manipulate your tone into new sounds impossible with a normal guitar. In addition to the original Freeze's abilities, the Deep Freeze features layering, adjustable attack/decay speeds, glissando, dedicated volume controls, and 3 modes: Latch, Moment, and Auto, making it powerful pedal punching well above its weight.

The Deep Freeze allows for instant sound freezing in three modes of operation. Latch freezes sound each time the footswitch is pressed until the effect is bypassed, while Moment mode freezes sound only while the footswitch is held down. Auto mode captured sound automatically each time it senses signal above its threshold for virtually foot-free freezes. These three modes make it easy to operate the Deep Freeze in a way that fits any playing style.

Controls on the Deep Freeze let you further tailor the operation of the effect. Separate DRY and EFFECT volume controls let you blend signals from subtle backing to 100% effect experimentation. GLISS adjusts the morph time between freeze sounds creating otherworldly soundscapes. The SPEED/LAYER knob adjusts either the attack/decay time of the effect in Moment and Auto modes, or the amount of layering possible in Latch mode which makes playing impossible chords possible!

Notes: 30 fully polyphonic pitch-shifting options under 15 square inches!

Offering a total of 30 pitch shift options and expanded controls, the Pico Pitch Fork is the next evolution in pitch shifting from Electro-Harmonix. The original Pitch Fork has garnered praise from all styles of player at every level and the Pico Pitch Fork brings even more features to the celebrated pedal in an impossibly small package.

The Pico Pitch Fork features 10 pitch shift intervals and three modes of pitch-shifting - Up, Down and Dual. Dual mode features specially paired pitch shift intervals to allow for more musical effects.

Controls on the Pico Pitch Fork are simple and effective. SHIFT selects the Pitch Shift interval. BLEND sets the wet/dry blend of the output mix while VOL adjusts the overall output volume. SWEEP controls pitch bend sweep time when toggling between bypass and effect and back to create automatic whammy effects. The Pico Pitch Fork's footswitch can operate in two modes: Latching and Momentary. Latching turns the effect on with one footswitch press and off with another while Momentary turns the effect on only when the footswitch is being held for instant bursts of pitch-shifting pandemonium.
