E-mu | E4XT Ultra


The E4XT Ultra has 64 MB RAM compared to the "normal" E4X Turbo.

E-mu Systems is proud to offer two new Professional Digital Sampling Synthesizers certain to meet the needs of today's working musician: the E4X Turbo and the E4X. Both are designed to provide superior sound quality, unprecedented hardware features and advanced sound synthesis capabilities.

Unprecedented Polyphony

E-mu Systems is the only company in the world that offers 128 voice polyphony, so don't settle for half an orchestra. Every sound is heard and decays exactly as designed; note rip-off is a thing of the past!

Loaded with Features

The E4X Turbo comes fully equipped, featuring standard 128 voice polyphony, 16 MB RAM (expandable to 128 MB via 72 pin SIMMS), a 1 GB hard drive loaded with over 400 MB of sounds and three additional CD ROMs. The E4X comes with 4 MB of RAM and 64 voices that can easily be upgraded to 128 voices via our 64 Voice Hardware Option Card.

Both the E4X Turbo and E4X come standard with more than 400 MB of sound data. In addition to the power to create and edit new sounds, there are thousands of presets located on the internal hard drive. Using SoundSprint TM, presets can be auditioned and loaded within seconds. E-mu's Digital Modular Synthesis software is at the heart of the system, offering advanced synthesis capabilities: 21 Z-Plane filter types, 32 voice layering, 128 voice cross switching or fading, and 18 patchcords per layer. In addition to the synthesis capabilities, both samplers support analog and digital sampling/re-sampling, a 16-track sequencer with standard MIDI file playback, Stereo Time Compression with tempo based phase lock and Graphical Waveform editing.

EOS 2.5 Software

Both the E4X Turbo and the E4X run the new EOS (Emulator Operating System) Version 2.5 software which includes a new enhanced SCSI subsystem and full Sysex implementation for remote control by either Macintosh or PC.

Sampling made fast and easy

These powerful samplers make sampling fast and easy by automating numerous tasks. Connect a microphone, press "sample" and the EOS software will automatically truncate, loop, normalize and place your sample into a preset. The E4X Turbo and E4X lead the way towards true point-and-click sampling!

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
