The SP2016 has been designed as an extremely versatile and capable general purpose audio signal processor. The hardware designs required for a no-compromise, natural sounding digital reverberator meeting Eventide performance standards are also capable fo a wide variety of other audio effects and functions.
Exploiting the full range of capabilities of the SP2016 presented a real design challenge: How to avoid a dense thicket of front panel controls, yet easily allow the user to access, adjust and program every possible combination of effect, parameter and control functions. And, importantly, how to accommodate from the outset any special control requirements of programs to be designed in the future. Eventide's R&D has met this challenge with a universal control panel. Deceptively simple in appearance, this handful of easily learned controls gives the user full control of all functions. The SP2016's computer-controlled alphanumeric display guides you through all control functions, one step at a time. Input, output and i/o mix controls; LED status indicators and level meters are also provided on the front panel.
Up to 65 different sets of program and parameter presets can be stored and selected by the user. The programs are stored and retrieved by paging through alphanumeric user-selected names for each preset. These non-volatile presets are protected against accidental loss, even if power is interrupted. And if previously entered parameters are changed, the unit will continue to remember the original values.
Extensive self-test capability is standard with the SP2016. Should a problem develop, the SP2016 will spot it and identify the likely cause. A special continuous test routine will repeatedly test the entire unit or specific sections you designate. . .ideal for locating any pesky intermittent problem.
MIDI interface capability for the SP2016 is scheduled for Spring 1986 availability. IEEE-488 (a computer industry standard) is optional on the SP2016. A palm-size hand-held remote is available as a low-cost option. This amazingly compact remote duplicates all the processor control block functions of the SP2016.
A remarkable breakthrough. Because of the hardware complexity and unique software requirements of this type of product, development of new programs has heretofore been limited to product specialists at the factory. Now for the first timed in the industry, Eventide makes it possible for the SP2016 owner to create programs for specific applications. This is accomplished by Eventide's Signal Processor User Development System (SPUDSystem). This integrated hardware/software development system is designed for people with general knowledge of and experience with audio signal processing. No specific knowledge of advanced programming techniques is required. SPUDSystem is currently supported on IBM PC/XT (or compatible) and Hewlett-Packard personal computers. In addition to applied practical purposes, such as the creation of new effects, the SP2016/SPUDSytem package together form an ideal teaching and experimental tool for college classes and research in signal processing.
The Eventide SP2016 Effects Processor/Reverb was designed from the start to accommodate advances in the art of digital signal processing. Now, Eventide has developed a software package that truly fulfills the promise of the SP2016. The Generation II software package, standard with every SP2016, offers the user a range of reverberation and effects programs of incomparable quality and utility. A brief description of the standard programs follows. But while the functions of an audio effect can be easily described, audio quality and effect characteristics simply cannot be adequately communicated in print. Determinations about naturalness and density of a reverberation program, for example, are highly subjective in nature. Our hardware designs and software algorithms are unique to Eventide. We strongly urge you to audition the SP2016 along with any other units you may be considering. Notice the smooth decay and absence of "discretes" in our reverberation programs. Hear for yourself the incredible range and versatility of effects programs such as loop edit and multitap delays.
Plate Reverb and High-Density Plate - Extremely natural plate simulations that retain "good manners," even at long decays.
Standard Room Reverb - With especially convenient and useful preset parameters.
Stereo Room Reverberation - Ranks with the best sounding limited-purpose dedicated room simulation devices, yet it's just one of the many programs you get with Generation II. Offers full user control of eight parameters.
Generic Reverb - The Eventide SP2016 utilizes far more sophisticated reverberation algorithms than most other digital reverbs. . .even units that are physically much larger and cost far more. Thus, the SP2016 is capable of smoother, more natural sounding reverb. However, some user applications may call for the harsher characteristics of less sophisticated reverbs. For these applications, Eventide has created this Generic Reverb program which emulated the reverberation characteristics of these reverbs. Offers nine user-adjustable parameters.
RMX Simulation Plus - An uncanny simulation of the most popular RMX16 reverb programs. The SP2016's full stereo design simulates TWO RMX16's at once! Choose any combination of Reverse, Non-Linear and Natural reverb programs on the SP2016's two independent channels.
Gated Reverb - An effective output gate mated to an extremely dense, Eventide quality reverb program. Gate attack, decay and threshold are adjustable, along with standard reverb parameters.
Lossless Room(tm) - Add layer-upon-layer of sound in a simulated room where sound never decays. The original infinite-type program.
Loop Editing - A single-channel program which allows the user to sample a short (1.63 seconds at 16 kHz bandwidth or 3.26 seconds at 8 kHz bandwidth) segment of audio and then play back all or any portion of that segment on command. After capture, the segment can be edited from either end. Playback can be initiated either as a "one shot" or continuous loop. Playback is triggered from the SP2016 front panel, or from a remote switch, or by an audio trigger input.
Multitap Delay - A powerful program which offers an incredible range of "unreal" reverberation and other effects. Select from one to 50 taps in mono, one to 25 in stereo. An additional feedback tap can be separately positioned. Six different envelope shapes are available, along with 11 different tap spacing choices. In all, a dozen different user adjustable parameters make this one program capable of many, many different effects.
Time Scramble - Uniquely scrambles audio in the time domain. Scramble rate is adjustable and segment length can be fixed or random. The amount of overlaying of the segments is variable. This effect sounds like nothing else!
Chorus - Adds from two to eight voices to your original signal. The voices can be varied in their placement around the listener.
Flanging and Envelope Flanging - You've never heard a flanger sound like this. Up to ten parameters - adjustable over a wide range - put you in total control of the effect. Envelope follower function allows an external audio signal to control the flange sweep.
Band Delay - Separates the audio input into four frequency ranges and lets you control the time delay of each frequency band, in any order.
Musical Combs - Another program which can produce a wide variety of different effects. A pair of coupled digital comb filters are tuned to correspond to the musical intervals of a two octave musical scale. The type of scale can be specified by the user. In addition to the wealth of musical effects available, many robotic-type vocal effects can be created.
Dual Digiplex® and Long Digiplex - Our digital simulations of multiple-head tape echo. Unlike tape echo units, noise never builds up, no matter how long the decay.
