"Eventide Inducted into TEC Award Hall of Fame, 10/5/2007"

"Eventide Studio Quality Effects Pedals Information" Eventide Inducted into TEC Award Hall of Fame for H910 Harmonizer Pitch Processor 10/5/2007 - Anthony Agnello honored for developing original pitch processor — The prestigious TEC Awards Hall Of Fame Committee recently inducted Eventide for its 1974 innovation: the H910 Harmonizer® effects processor, which has been said to have turned music production on its head and ushered in a new era of music creation.

 The Eventide H910 Harmonizer effects processor forever changed the complexion of music enabling producers and artists to add texture to their recordings and performances in ways heretofore unimaginable.

 Yes vocalist, Jon Anderson, tested the first prototype. Users soon found all sorts of applications, ranging from regenerative arpeggios to bizarre sound design effects to lush guitar or vocal fattening.

 Early customers included New York City’s Channel 5 putting an H910 to work, downward pitch shifting the audio portion of “I Love Lucy” reruns that were sped up to squeeze in more commercials. Music engineered on the H910 became the soundtrack of the seventies and eighties drawing praise and extensive use from a select group of top artists and producers.

 Ideal for vocals, guitars and horns, the Eventide H910 was invented by then-engineer, now-chief technology officer, Tony Agnello. In 1974, Agnello conceived of a harmony processor but had little idea that he was creating a classic tool for the most successful artists of their generation. Jimmy Page was an early fan, incorporating the H910 into his guitar rack, and, similarly Frank Zappa employed it heavily as part of his guitar sound. Producer Tony Visconti used the H910 to achieve the now-legendary snare sound on David Bowie’s Young Americans, and Tony Platt did likewise on AC/DC's Back in Black. Eddie Van Halen and Steve Winwood also used the H910, each owning two of the units and incorporating them into their live and studio set-ups.

 “I conceived the H910 as new kind of musical instrument. My goal was to give musicians and engineers a new way to create and sculpt music; to create an instrument that allowed them to change pitch, to add depth, and to layer harmonies,” Agnello said today.

 “I was ecstatic that people like Frank Zappa and Tony Visconti embraced it and used it to explore new audio landscapes. After all, I was just a young engineer and we were a small company on the margins of the New York City studio community.

 Now, we’re all a little older and a bit more established in the business, and the TEC Award Hall of Fame Award is especially gratifying.” The Eventide H910 offered pitch shifting and digital delay with feedback enabling subtle thickening on voices and guitar tracks. Since 1971, Eventide has evolved and grown and has become a staple in the music production community with various hardware and software tools for the artist and producer.


"The Power, The Performance, The Heritage of Eventide Audio Effects in a Single Rack Space Unit"

Dual Effects Block Architecture

Eclipse is the only effects processor in its class to feature 24-bit digital conversion and 96kHz sampling. We’ve packed almost 100 algorithms into Eclipse along with a two effects block design. The dual routing configurations let you use Eclipse as two independent effects processors; ideal for the smaller, budget-conscious studio. The two effects blocks’ inputs and outputs can be configured for stereo or mono. Or, select a preset that combines two algorithms or recursive combinations for big multi-effects without sacrificing quality.

Classic Eventide Effects

We’ve packed Eclipse with effects Eventide is famous for. There’s quick, seamless pitch shifting including our innovative Micro pitch shift, which FOH engineers and vocalists have come to rely on for turning good vocal performances into great ones. Eclipse boasts no fewer than 11 reverberation algorithms plus four plex algorithms. Originally developed for Eventide’s industry-standard Orville and DSP 7000 series, these reverbs have been carefully and faithfully transplanted into Eclipse. And all reverbs are true stereo in and out, not mono in, stereo out. The vast array of delays lets you design lush, dense soundscapes. You’ll find band delays, chorus delays, comb delays, ducked delays, ring delays and pan delays. And with 20 seconds of memory per effects block, Eclipse is a looper’s delight. It’s easy to get lost in the 20-second mono loop, 10-second dual loops, 20-second reverse loop, and 10-second dual reverse loop. Remember, these looping presets running on one FX block leaves the other FX block available for adding texture or dimension.

I/O Ports for Maximum Versatility

The rear panel has a port to support all your needs, including AES/EBU, S/PDIF and ADAT™ Lightpipe™ for digital applications. Analog balanced XLR-type and unbalanced ¼” inputs and outputs. The ¼” jacks even accept a high impedance instrument signal. There’s Word Clock In and Out on BNC connectors and two pedal ports for performers. And of course, full MIDI (IN/OUT/THRU) including an external power jack for your cabling convenience. There’s even a serial port which makes it easy to update Eclipse’s software from the internet; no chip changing needed.

Easy Set-Up and Operation

The Eventide knob and keypad make setup and operation easy. If you’re familiar with our H3000 series Harmonizer units, you’ve already got the basics.

Hot Keys

Hot Keys provide quick access to the eight most important parameters on every preset. In addition, you can customize the Hot Keys on any preset to create your own unique program.

Dedicated Tap Button

The tap button isn’t just for delays. It’s also the frequency rate of the LFO modulating your sample and hold filter, or the speed of your autopanner or tremolo. The Tap function can be set to average out from 2 to 12 taps.

Design Your Own Presets

You get a complete selection of presets, but eclipse makes it easy to design your own. Load one or two algorithms, pick a routing, assign the Hot Keys, and tweak.

Flash Card Slot

Your presets can be stored easily in the Eclipse or on an affordable compact flash card. Transferring presets from on Eclipse to another is simple with compact flash cards.

Unleash the Sonic Beast

Whether it’s live performance, front-of-house engineering, or quality studio processing, Eclipse gives you the tools you can depend on in one compact, professional package. After all, Eclipse is not just an effects box, it’s an Eventide.

1/15/2009 - Update adds TimeFactor and ModFactor effects to Eventide's best-selling rack processor 

Eventide today announced the release of V4.0 software for its Eclipse Harmonizer® processor, further demonstrating its commitment to the installed base of Eclipse owners and production icons. The Eclipse is attracting attention from musicians and engineers alike and the new software significantly accelerates program load time and incorporates the entire catalog of TimeFactor and ModFactor effects. Expanding the number of effects to 111 and the number of presets to 450, v4.0 software adds the ability to run full Eventide stompbox algorithms and other select Eclipse effects simultaneously. As an example, users now have the ability to run stereo delays feeding an ambience effect while the stompbox parameters will be mapped to the four hot keys on the Eclipse.

Widely used by professional touring musicians, front of house engineers and top recording studios alike, the Eclipse Harmonizer comprises Eventide’s best effects in a compact dual engine processor which is capable of running two stereo effects at one time, either in serial or parallel. Any parameter can be adjusted in real time using a standard MIDI foot controller or an expression pedal, making the Eclipse one of the most expressive effects processor available.

“This milestone software release makes the Eclipse even more enticing,” noted Ray Maxwell, Eventide vice president of sales and marketing. “We continue to add value and optimize the performance of this superb hardware processor with the addition of our best-selling TimeFactor and ModFactor effects. With this update, the Eclipse maintains its edge as the go-to rack processor for performance or studio. Now in the studio, you can have the very same effects which appear in the stompboxes accessible with S/PDIF, AES or ADAT digital I/O.”

The new software will be released to public beta by the end of February and will be released to production in March 2009. Eclipse V4.0 software is a free download for Eclipse owners who have registered their product at Eventide.com.
