DSP4500The Eventide DSP4500


The outstanding success of Eventide's DSP4000 Ultra-Harmonizer¨ brand studio effects processor has led to two additional versions of the platform: The DSP4000B , with specially written software for broadcast and production, and the GTR4000, the industry's first and only professional guitar processor. Eventide has also created a versatile internal sampler for use with the 4000 series models.

It didn't take long before users of one DSP4000 version began asking for some of the program presets found only in the other versions, and Eventide has met that demand with plug-in PC (PCMCIA) cards. But creative people being what they are, it's not surprising that a number of users want all the preset programs available in the DSP4000, GTR4000 and DSP4000B. For the user who wants it all, juggling PC cards is not the ideal answer.

Thus, the Eventide DSP4500 was born. This limited edition model comes standard with every program preset found in the DSP4000, GTR4000 and DSP4000B... and then some. The "then some" is quite a package in itself. It's Alchemy 101, a brand new collection of 225 presets from Scott Gilfix. Alchemy 101 will be available to DSP4000 owners as a $495 PC card. But it's built right into the DSP4500. You get over 1000 program presets in all, far more than any other effects processor ever made.

And we're not through yet. The DSP4500 includes as standard, an 87-second internal sampler. And a unique look, with a ruggedized heavy gauge all-metal front panel.

The DSP4500 is definitely a vehicle for unlimited creativity. What makes it a limited edition? Eventide has priced the DSP4500 to be an exceptional value. So exceptional that the number of DSP4500 units to be produced must be limited. (You'd pay thousands of dollars more if you bought a DSP4000, all the program preset cards and the internal sampler separately.)


At the heart of the DSP4500's versatility is its ground-breaking design. Conventional effects processors include a limited number of fixed digital processing algorithms. In these units, all programs and user presets Ñ no matter how many or few Ñ are simply variations of these fixed algorithms. But the DSP4500's 1000+ software factory programs and presets draw on a newly-expanded roster of 147 distinct effects modules to create a wider variety of truly distinct programs than ever before possible. What's more, the unit's object- oriented Algorithm Construction Kit function lets users (and third- party developers) build totally new effects algorithms by linking modular effects "building blocks" which are presented on the unit's large, graphics-based LCD screen.

To use the Algorithm Construction Kit function, you create new effects from the front panel or from your PC, using Eventide's full screen graphical editor, via the DSP4500's Patch Editor Ñ essentially a virtual patch bay. You can choose from over 147 effects modules and connect scores together in one preset, in whatever combination and configuration you choose, much the way you'd use patch cables when working with a modular synthesizer. Put pitch shift after a reverb, or string together effects and put EQ on only the ones you want Ñ you decide which blocks "talk" to which. The unit's internal digital mixing function seamlessly combines these building blocks to create a virtually unlimited number of programs (6x1025 at last count) for limitless creativity.


The unparalleled processing power of this unit is just one half of the DSP4500 equation. The other half? All the innovative ways our software designers have harnessed this power.

For starters, there's pitch shifting that stands in a class by itself. The new DSP4500 features a fully digital real-time pitch transposer. The DSP4500 generates up to eight simultaneous voices of pitch shifting, or four pitch shift voices plus simultaneous stereo reverb. It features the world's first programmable multi-diatonic pitch transposer and the world's best multi-voice reverse shifter with delay. The DSP4500's pitch change capabilities include an amazing eight-octave pitch shift range.

Everything you need in a reverb, from small and ambient reverb to large rooms and halls, you'll find among the DSP4500's world class digital reverb programs, including more power and flexibility of parameter control than any other reverb at any price. The DSP4500 can build reverb presets with up to four pitch shifts, allowing a very subtle chorusing for lush vocals and string instruments. And only the DSP4500 allows for sequenced reverb segues from lead vocal to chorus and back Ñ a powerful time saver for busy professionals.


You'll find mastering quality EQ and compression, with up to 6 bands of stereo EQ, all on the digital I/O bus. The DSP4500 lets you put compression on the equalizers and mix them with other modules. Plus, you have dynamics processing, envelope generators, both transistor and tube-simulation distortion, LFOs and more to work with... the DSP4500's capabilities are almost endless. And while the DSP4500 embodies today's most forward thinking in signal processing, it also respects the past. The DSP4500 includes practically every wonderful and classic effect Eventide has ever created, all in a single box! These include the lushest Chorus progams in the universe, the best Phaser, Flanger, Delay, Diatonic Shifter, and Dynamics Processors available, just to name a few.


The DSP4500 contains every one of the effects that made the GTR4000 the choice of the world's top players. Case in point: The incredible Picker's Paradise template, a pre-configured master effects routing template that makes it easy to tap into the creative power of the DSP4500's patch editor. Picker's Paradise lets you create ten effects boxes right at your fingertips. Each one full bandwidth, full quality. Compare that to typical multi-effects boxes, with effects quality that starts off limited and degrades from there as you string effects together. To a pro, this alone is worth the price of the DSP4500. The DSP4500 also lets you create and customize "virtual pedalboards" Ñ up to six simultaneous pedals, with instant on/off and parameter changes in real time Ñ strapped via MIDI to your favorite MIDI foot controller. Real time switching between pedals assures instant effects access during solos, rhythm or lead breaks.


Top name artists have seized the power of the 4000 platform to create custom presets. People like Joe Satriani, Steve Vai, Trey Gunn (King Crimson), Jimmy Olander (Diamond Rio), Matt Henderson and Michael James have written the most expressive presets ever created for any effects processor. Scott Gilfixs new Alchemy 101 library of presets also debuts in the DSP4500. This amazing collection includes a chromatic tuner (accurate to one cent), tap tempo delays, new reverbs and some exciting preamp flavors (you can plug your instrument right into a DSP4500). Its dynamics bank is packed with useful compressors, noisegates, panners and tremolos.


The versatility of the DSP4500 also extends to post production and broadcast, thanks to a unique set of software programs created by sound designer Jay Rose. Dozens of audio environments that would be impossible to achieve with most processors are instantly available with the DSP4500. Just press a button and this is your captain speaking from the cockpit of a 747. Press again and now it's the kid at the drive-thru window at a fast-food place asking if you want fries with that. Another press and you'll hear your words coming out of a computer voicechip, or the TV in the next room, or a cellular phone. Fantasy voices are just as easy. Is that your conscience talking back to you, or is it the "dark side of the force"? It's a snap to create a whole cast of character voices or "strange places" effects. Whether you're live on the air with a "Morning Zoo" or doing TV, radio or film postproduction... or even looking for unique effects for a hot rap track, the DSP4500 has the sounds you know you want, plus the sounds you've never heard before.


The DSP4500 comes standard with a built-in 87 second sampler (43.5 seconds in stereo), which adds tremendously to the versatility of the unit. Sounds captured by the sampler can be combined within many DSP4500 presets. Advanced stereo looping and multiple looping capabilities allow several samples to be stacked and independently edited, pitch shifted and/or time compressed or expanded. Tap tempo looping is also provided. Audio samples and edit parameter values can be downloaded to the PC card for convenient removable storage. The internal sampler also allows full on-the-fly Timesqueeze¨ compression/expansion. Commercial spots can be compressed with no need to varispeed the source material.


The DSP4500 lets you use more than one program at a time; in fact several programs can run in various combinations. While some other professional processors can split their power into two using A/B Machine Mode, the DSP4500 goes well beyond that. Its enormous processing power can be split into a number of virtual processing "machines." In addition, the DSP4500's ability to run multiple programs simultaneously gives it crossfade capability where desired. A unique Effects Segue feature provides the smoothest transition between presets, with fade-in/fade-out times adjustable from instantaneous to 60 seconds. With the DSP4500, you can fade or segue gracefully from one program into another. It's the equivalent of having an entirely new category of effects from which to choose.


The Eventide DSP4500 processor includes a front-panel slot for removable PC cards. In addition to storing user presets in RAM, a user can create and save presets on a memory card and transport them to 4000-series units in other studios, or just save them as a safeguard against the prying eyes and ears of other users. New and third party programs can be plugged into the unit via the PC card slot, such as "Masderring Lab," which offers a suite of digital mastering capabilities. This program provides precise digital compression and limiting, as well as a 4 band fully parametric EQ on both input and output signals.


The DSP4000 provides full 24-bit AES/EBU and S/PDIF digital I/O for an all-digital signal path as well as standard XLR-type analog inputs and outputs. Optimal audio quality is assured via 24 bit A/D and D/A converters and 56-bit internal processing for >96 dB dynamic range and .005% THD. With available sample rates of 32 kHz, 44.056 kHz, 44.1 kHz and 48 kHz, audio bandwidth at the analog connectors is up to 22 kHz. The DSP4500 includes MIDI In/Out/Thru jacks. The rear panel sports a foot pedal input and two foot switch inputs, plus two relay-closure outputs for controlling guitar amplifier channel switching. The configurable "Kill" switch can function either as a relay bypass and an electronic bypass, or as a mute on the analog input; and either as an electronic bypass, or as a mute on the digital I/O.

The limited edition Eventide DSP4500 Ultra-Harmonizer brand effects processor isn't just a great signal processor. It's three of the most versatile, most musical, most creative, most programmable signal processors ever built. It's over 1000 sonically impeccable program presets, plus the ability to create your own. It's the power of a built-in sampler. It's the greatest value ever in a professional processor for recording studios, live performance, radio and TV stations and post-production facilities. But most of all, it's the box that shatters all previous limits to give you that extra edge.
