The E6400 is basically the same as the Ultra version. The Ultra has FX, and can have a hard drive installaed. Also the processor is a bit faster.

E-MU SYSTEMS introduced the first Emulator in 1981, forever changing the world of electronic music. Now we are proud to introduce the Emulator 4 Ultra, a professional sampling system with unrivaled speed, versatility and fidelity that allows you to create complex sounds and massive sequences like never before. The E4 Ultra line of samplers features new hardware, new software and a host of new options, giving you the ability to realize any sound imaginable.
Ultra Advanced Hardware
The E4 Ultra uses a new 32-bit RISC processor, giving you ultra-fast MIDI response time, SCSI, DSP operations and sampling. All E4 Ultra models are upgradeable to 128 voice polyphony (standard on E4XT Ultra) and can address up to 128 MB of RAM (E4XT Ultra ships with 64 MB standard, the E6400 and E-Synth Ultras ship with 16 MB standard). With this combination of polyphony, memory capacity and blazing processor speed, you can trust the E4 Ultra to deliver your most intense layered sounds and sequences with dead-on timing and pristine fidelity.
Ultra Featured Software
The E4 Ultra ships with the new EOS version 4.0 operating system which offers a host of breakthrough features such as E-MU's "Beat Munging" technology (more on that later!). Also new to EOS 4.0 are substantial improvements to the editing functions for faster and more intuitive loop point placement, enhancements to the sequencer, and the ability to import AKAI S-3000 format sample libraries.
EOS 4.0 also comes with EOS Link, a Mac or PC software application that allows you to control the Emulator from your computer desktop. Combined with Gallery's EOS Browser and EOS File Assistant software, you can now fully integrate the E4 Ultra with your computer to catalog your sounds and transfer samples, presets and multimode setups between your E4 Ultra and various storage media. The new EOS 4.0 software supports hard drives up to 18 GB, which means your vast sound library can be on-line at all times.
Ultra Versatile Upgrades
E-MU also offers versatile new hardware upgrades for the E4 Ultra, like the 16 output / 8 input ADAT card which allows you to have 16 outputs all in the digital domain for easy digital studio integration, as well as 8 digital inputs for sampling from ADAT or flying in vocals or sound FX to be manipulated with the E4 Ultra's powerful DSP engine. Need rapid access to onboard sounds? The new 32 MB Flash memory boards give you the ability to store sounds in non-volatile FLASH memory for instant recall, and the revolutionary 32-bit, 32 channel R-Chip FX card will blow your mind with advanced FX and cutting edge DSP operations (FX card available Summer '99). With ten expansion ports (seven internal and three rear panel), you can customize your E4 Ultra with upgrades that are custom tailored to the way you work. The Emulator 4 Ultra is an ultra-smart investment that will evolve as your music and needs change.
Ultra Accessible Sounds
The E4 Ultra ships with a complete sound library on CD-ROM, 9 discs in all with over 2GB of sounds, an incredible value that gives you instant access to some of the world's greatest sounds. And if access to the incredible Emulator Sound Library isn't enough, the E4 Ultra reads AIFF and .WAV files from floppy, and is compatible with the Roland S-700 and AKAI S-3000 / 1000 / 1100 sound libraries, allowing you to play your old favorite sounds.
The E4 Ultra introduces Beat-Munging, a new real-time DSP tool that analyzes your drum loops and phrases to automatically determine the BPM and perfect loop for your sample. Beat-Munging also allows you to change your loop's time (i.e. from 4/4 to 7/8), tempo, swing and move and switch beats within your loop, all in real time. Beat-Munging gives you unprecedented rhythmic control over your audio and may radically change the way you create and manipulate loops and grooves either way, you will only find this breakthrough technology in the E4 Ultra.
You can choose from three different E4 Ultra models depending on your needs and budget. For those who demand the best, there is the E4XT Ultra, our top of the line. If you need a sampler with built-in sounds, there is the E-Synth Ultra. For those looking for an affordable way to take advantage of all the power the Ultra series can provide there is the E6400 Ultra. Both the E-Synth Ultra and E6400 Ultra can be upgraded to full E4XT Ultra status by adding the user-installable options.
Ultra Smart Investment
We believe that purchasing an E-MU sampler is an investment. If you invested in an E4X, E4XT, e6400 or E-Synth Rack, you will be pleased to hear that you can upgrade your rackmount sampler to Ultra status with a processor and software upgrade at the E-MU factory. We can turn your already powerful Emulator investment into the most advanced sampler in the world at a very reasonable price. Just one more reason to choose an E-MU sampler.
In addition to its many new features, the E4 Ultra delivers all of the qualities that you have come to expect from E-MU: pristine sound quality, unsurpassed filter technology, user-friendly operation and a philosophy of versatility and upgradeability that results from 18 years of sampler development. Regardless of your project, the E4 Ultra will always deliver your sound accurately, placing the creative power of sound manipulation where it belongs in your hands.
