E-mu | E4 Platinum


E4 Platinum is E-MU's flagship sampler and latest addition to the legendary Emulator® 4 Ultra Family. E4 Platinum represents the pinnacle of sampling technology available to musicians today. With its powerful effects and synthesis engine, E4 Platinum is the ultimate sound design tool in the world, allowing you to create any sound imaginable.

Ultra Hardware 

The E4 Ultra features a completely new hardware architecture that provides you with a host of benefits. The E4 Ultra’s 32-bit RISC processor gives you ultra-fast MIDI response time, SCSI, DSP operations and sampling, making your time more productive. E4 Ultra samplers either ship or are upgradeable to 128 voices of polyphony (except the E5000 Ultra), allowing you to layer and sequence complex sounds without fear of losing any notes, freeing you to concentrate on the creative process and not on the limitations of your sampler. You can install up to 128 MB of RAM, offering you tremendous flexibility in manipulating huge banks of quality sounds. The E4 Ultra also accommodates Flash ROM, allowing you to create and edit custom soundsets that are instantly accessible. With its combination of polyphony, memory capacity, and blazing processor speed, the E4 Ultra will deliver your most intense layered sounds and sequences with dead-on timing and pristine fidelity.

The E4 Ultra ships with the latest version of EOS (Emulator Operating System), which offers support for E-MU’s RFX-32 Card, faster and more intuitive loop point placement, enhancements to the sequencer, and many other breakthrough features. EOS has constantly evolved through the years, providing you with an unparalleled software upgrade path full of new features that you can easily load into the E4 Ultra’s operating system memory via floppy disk. Inspired engineering has been combined with user feedback to create new EOS features like Beat-Munging, providing you with solutions to real-world problems and keeping your Emulator state-of-the-art.

E-MU’s revolutionary RFX-32 Card is an effects/mixer upgrade card for all E4 Ultra samplers (standard with the E4 Platinum) that offers you up to 16 simultaneous studiograde effects. The RFX-32 Card plugs into your E4 Ultra’s internal expansion slot, and allows you to route both internal and external signals through its 16 pristine stereo effects processors, and can be configured countless ways over multiple FX mixer channels. E-MU also offers three new 24-bit I/O upgrade cards that give you pristine converters and specifically support the special features of the RFX-32 Card. And the RFX-32 not only adds effects to internal and external audio, but it also allows you to process your sounds using MIDI control over dozens of parameters for incredible realtime performance control. It’s like having a 32-bit digital mixer and effects system inside your Ultra!

Beat-Munging is a new real-time DSP tool that analyzes your drum loops and phrases, automatically determines the tempo, and then perfectly loops the sample for ultimate groove preservation. Beat-Munging also allows you to change your loop’s time signature (i.e. from 4/4 to 7/8), tempo, swing factor and individually manipulate 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— and you will only find this breakthrough technology in the E4 Ultra.

The E4 Ultra also provides you with a large palette of DSP tools like stereo phase-locked time compression, pitch change, Doppler shift panning functions, sample reverse, transform multiply, digital re-sampling, and an Aphex Aural Exciter algorithm to add clarity and brilliance to your sounds. The E4 Ultra provides the tools that allow you to transform your original, raw waveforms into new, complex timbres that will serve as the building blocks for creating inspired presets. From sound effects and film scores to the latest dance grooves, the E4 Ultra will always deliver your sound accurately, placing the creative power of sound manipulation where it belongs— in your hands.

With the increasing convergence of digital and analog technologies, the E4 Ultra has been designed to seamlessly integrate with your computer and the rest of your studio. The E4 Ultra’s (except the E5000 Ultra) ship with EOS Link, a software application that allows you to control the Emulator from your computer desktop. Combined with EOS Browser and EOS File Assistant from Gallery 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. And the E4 Ultra’s 50-pin SCSI connector offers you compatibility with a variety of mass storage devices, including external hard disks, CD-ROMs, DVD-RAM, Jaz®, Zip™ and others, giving you true flexibility in storing your sounds and projects. You can use the E4 Ultra with a wide variety of audio/MIDI software by third party manufacturers to enhance the Emulator’s many professional features even further, including some specifically designed to support E-MU samplers. The E4 Ultra also integrates into your digital studio with AES/EBU digital I/O, Word Clock I/O, and ADAT® card, keeping your audio entirely in the digital domain.

The Emulator 4 Ultra is more than just a sampler– it is also a powerful synthesizer with Digital Modular Synthesis (DMS). DMS technology lets you patch control sources to the synthesis parameters found in each preset for an incredible number of modulation possibilities. E-MU’s roots go back to the days of analog modular synthesis, and we developed DMS to allow you to recreate desirable analog synth features and effects while staying entirely in the digital domain. You can use the E4 Ultra’s virtual Patch Cord architecture to easily target the 21 patented Z-Plane filters, 2 LFOs, tuning functions, and three fully independent six segment envelope generators (per sample!) to create any sound imaginable. The E4 Ultra provides you with the world’s most powerful, professional synthesis tools to allow you to create that "just right" sound that is uniquely yours.

Our Emulator samplers have always been known and trusted for their musical warmth and sonic integrity. The E4 Ultra gives you 128x over-sampling sigma/delta conversion to ensure that every subtle nuance of your original source material is captured during sampling. Our proprietary chip technology with 32-bit processing provides you with virtually distortionless pitch transposition over an incredible 10-octave range, giving you unmatched flexibility in the use of your samples, free of aliasing, clock noise and other digital artifacts. The digital-to-analog converters and balanced outputs provide you with increased headroom and the assurance that the E4 Ultra’s pristine audio quality is accurately translated to the analog domain. The E4 Ultra also imports other sample file formats with optimal sound quality, including the Roland® S-700 Series and AKAI® S-3000/1000/1100 sound libraries, as well having the ability to read AIFF and .WAV files from floppy. This compatibility allows you to play all of your old favorite sounds, while giving you access to the legendary Emulator sound library.

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.
