E-MU

E-64

 

Made in 1996

Emulator Æ: ('em-u-lat-er) n. A musical instrument with power, performance, superb sound quality,
advanced synthesis, and ease of use. Sets the standards for sampling and synthesis.

Sampling and Sound Design
The e6400's intuitive user interface makes sampling easy by automating tasks like looping,
normalizing, truncating, and sample placement. Sample your own sounds or playback any of the 400
MB of sound data that comes standard on CD-ROM - there's no limitation to the sounds you can
have. The e6400 includes 1000 sample and preset locations and the ability to upgrade to 128 MB of
memory, that's over 12 minutes of stereo sampling at 44.1kHz.

Superb sample playback is but one of e6400's outstanding features. The e6400 is armed with a
comprehensive palette of digital audio sculpting tools. These include loop, truncate, taper, cut, copy,
and paste as well as innovative DSP tools such as stereo phase-locked time compression, pitch
change, doppler/pan, reverse, exciter, and transform multiply. Internal digital re-sampling capability is
a very powerful feature that allows any sound generated at the output, including FX and sequences, to
be recaptured as a single new wave. Combined with Digital Modular SynthesisTM (DMS), DSP, and
FX, basic waveforms can be turned into new complex building blocks.

Audio Quality
The e6400 continues the long tradition of E-MU's professional audio quality. A key factor in this
quality (apart from 18 bit DACs and internal 24 bit precision) is the elimination of aliasing and clock
noise normally associated with sample pitch transposition by maintaining a constant yet selectable
sampling rate. This contributes to a warmth and smoothness in the Emulator sound that is quite
unique.

The e6400 offers the power of E-MU SYSTEMS' renowned Emulator Operating System (EOS) and
superb audio quality in a package perfect for the budget-minded professional. The e6400 comes with
stereo sampling, 4 MB of RAM and is fully upgradeable to E-mu's top of the line Emulator sampling
synthesizers, the E4X, and E4XTurbo. The e6400 breaks down the barriers of high-cost professional
audio products and makes them available for the most important system around - yours!

Sounds & SoundSprintÆ
The e6400 comes with more than 400MB of brand new sounds, together with some renowned
E-MUÆ classics. What's exciting about these patches is not only the great way they sound using the
real-time controllers and the extended voicing architecture of the e6400, but also the convenient way
that you can browse through the optional internal and external drives. It's just as if they were residing
in a "virtual ROM bank" - the big difference is that this particular bank is over 400 MB wide! The
SoundSprintÆ routine quickly pulls presets into memory one at a time as you browse through the
optional internal drive. Each sound is sculpted with its own samples, keeping the presets sounding
fresh and unique. And of course, the e6400 is fully compatible with the enormous E-MU CD-ROM
sound library - including the AKAI S1000/1100 and Roland S-700 series library.

Synthesis Features DMSTM
Digital Modular Synthesis describes the nature of Emulator sound design. Patching control sources to
synthesis parameters is the heart of preset modeling, and E-mu's early dedication to modular analog
synths is finding new life. Z-PlaneÆ filters, dual LFOs, 32 sample layers with individual access to
variable loop and start points, tuning functions, and three fully independent six segment envelope
generators provide the basic synth elements. These elements, along with the raw sampled wave data
are then targeted by real-time inputs such as faders and wheels or other control sources to model
unique, complex and expressive sounds.

Sixty-Four Voices Standard
A cornerstone of Emulator Technology is providing the user with high polyphony. Why is this so
important? There are two main reasons. One is the support that high polyphony provides for layering
sound elements - layering or stacking sounds is a natural, intuitive approach to voicing and sound
design. As long as there is polyphony to spare, extra layers can be molded into sounds to make them
richer and more complex. Another is sequencing, which typically places high demands on voice
availability. High polyphony means less chance of notes getting ripped off; it frees the natural creative
process overall and is one of the most important and fundamental assets provided by the e6400.
