The Eventide DSP7000, DSP7500 and ORVILLE Processors can integrate looping and/or sampling with all sort of FX. The open nature of these platforms allows the user to build his/her own custom algorithms, using VSIGFILE, a freeware Windows PC graphical algorithms construction application.

If the end user doesn't find what he/she needs in the extended factory presets libraries Eventide provides (more than 500 presets in the 7000, more than 700 in the 7500 and over 1000 in Orville), he/she'll be able to modify them or to create new structures from scratch, customizing with extreme details audio, modulation, control and UI.

Looping on Eventides is basically delay-based; you won't be able to do looping exactly like on a Jamman or EDP,but you will definitely get many other flavours that those units can't provide.

A few notes on hardware features of these machines:

DSP7000/7500 are 24bit/up to 96KHz STEREO units, w/2 analog ins/outs, AES-EBU and S/PDIF in/out.
ORVILLE is a 24bit/up to 96KHz unit, w/4 analog ins/outs and 4 digital ins/outs, 2 AES-Ebu or 1 AES+1S/Pdif.

We are releasing 2 ADAT boards:
One will add stereo ins/outs for DSP7000/7500. The other will add 8 ins/outs to Orville.

In the near future we will release another board for ORVILLE only, w/8 AES-EBU ins/outs. This version of Orville will only have a stereo analog in and out! Both boards can be added to Orville.

Orville DSPs have 4 inputs/4 outputs each, so programming of complex structures is possible, thanks to "Anything-to-Anything" routing. You can build all possible routings, feedback paths, just about anything you like...from the front panel or using ROUTING, a Windows PC applications. Routings can be saved on your PC, into Orville RAM and on Pcmcia cards.

Orville does QUAD audio! Imagine lopping+processing on 4 cabinets, or 8.

All machines have 2 rear panel inputs that can accept 1 pedal or up to 3 footswitches EACH for parameter real time control.

MIDI protocol is fully supported. All parameters can be modulated by midi cc, notes, pedals, switches, audio level, pitch....

We also have a remote controller, EVE/NET, that can control up to 4 units (any combo of DSP7000s/7500s/Orvilles), thru ethernet connection.

Evenet has 8 rotary encoders that are hard wired to the 8 parameters that you see on the display. Each encoder also features a click that allows storage of a full setup+routing+presets loading!

Hopefully this gives you an idea of available possibilities.

ORVILLE/DSP7000/7500 share an open modular nature: the user will be able to combine a big number of audio, control, math, UI, modulation modules from the unit database, working in a graphic environment and connecting modules with virtual patch cables. Currently database has about 250 different modules.

A group of fundamental modules are the core for looping applications:

• DELAY :
  a classic digital delay line with up to 32500ms.
  
  
• MICRODELAY :
  delay line with finer resolution, max 10920 ms.
  
  
• MODDELAY :
  delay line w/modulation input, max 10920 ms.
  
  
• REVDELAY :
  a classic Eventide Reverse delay, max 32500 ms.
  
  
• MULTITAP :
  a multi-tap delay line, with a selectable number of delay taps. Each tap has adjustable level, pan and delay. It can have up to 100 taps w/2000 ms. delay each.
  
  
• STEREOTAPS :
  another multitap delay line, w/stereo input and output, max 50 taps w/2000ms each.
  
  
• RAMPDELAY :
  a delay whose time increases linearly according to a control input, giving a high quality pitch shift until the maximum (or minimum) is reached, at which point, the pitch returns to normal. Max delay is 32500ms.
  
  
• REVERSE SHIFTER :
  another classic Eventide backwards playing pitch shifter. Max delay time is 32500 ms.
  
  
• PITCHTIME :
  This module phase coherently pitch shifts and/or time scales up to 8 channels of audio. It also has a built-in pitch detector whose results are made available through various control outputs.

  When time compressing or expanding, the lost or gained time is represented by a change in the delay through the module. For example, time compression causes the delay through the module to reduce, while time expansion causes it to increase. When the delay value reaches its maximum or minimum the time scale returns to real time.

  If the maxdelay value is set at its maximum value and timeAmt is set at say, 0.9 (90%) the time expansion will continue for 160 seconds until all the delay is used, at which point the output of the module will be delayed by 16 seconds.

  Time stretch or compression can be continuously retriggered. Let's simply say that this module has a max delay of 16000 ms and can do time stretching or time squeezing AND pitch shifting! In REAL TIME.

  All these modules use the main board delay memory, 43 seconds @48KHz, which is also used by reverb modules, pitch shifters and some filters. Any module can be used in many instances, allocating variable amount of delay memory, choosen by the programmer. For instance, you might have 4 delays using 10 seconds each.
  
  

• PLEX :
  The plex module provides a simple way of creating high quality reverberators. To create a reverberator, the outputs several delay lines are fed into the plex module and the outputs of the plex module are fed back to the inputs of the delay line. The plex module combines the delay outputs to produce an exponentially increasing density of echoes, hence a dense reverb. The signal that is to be used as the main input to the reverberator is connected to the "in" of the plex module. This is a classic Eno sound. You can make things even more interesting by experimenting with other modules besides delay lines in the feedback structure. If you only patch delay lines into the PLEX, you can get interesting variations of looping/verb.

All these modules are common to DSP7000, DSP7500 and ORVILLE machines.

DSP7000 has one single dsp chip, 4 times more powerful than a DSP4000 or a Pcm81 (to give you an idea). Its full delay memory is 43 sec.

DSP 7500 has the same dsp chip plus a sampling board with 174 sec memory @48KHz. Its full delay memory is 43+174 sec, if the sampling board memory is used for delay applications (LONGDELAY module).

ORVILLE has 2 identical dsp chips plus the same sampling board. Its full delay memory is 43+43+174 sec., if the sampling board memory is used for delay applications (LONGDELAY module).

Orville DSPs are named A and B: the sampling board is ONLY available on DSP A. The sampling board CAN'T be added to a DSP7000!!! So, if you are thinking to get an Eventide for looping, plan ahead of time; DSP7500 or Orville are the choices w/bigger memory.

More modules :

LONGDELAY (DSP7500 & ORVILLE) : a LONG delay line that uses the sampling board memory, up to 174 sec @ 48KHz sampling rate. Like all other modules, it can be used in many instances: you could have a preset w/4 LONGDELAYS, w/43 sec each, or 10 lines w 17 sec each or any combination of mono/stereo delays, within the max delay memory available.

DELAYSAMPLER (DSP7500 & ORVILLE) : This is a small mono sampler that uses delay memory rather than sampler memory. This means that it can be used in either (or both) machine A or machine B in Orville. It also limits the maximum recording time to a total of 40 seconds per preset (at 48kHz). Use the normal sampler in machine A if you need longer recording times, or higher quality varispeed, as well as pitch change. From 4 to 8 of these samplers can be used in a single preset, so they can be paralleled for stereo or quad. This sampler is an old style one: when you use change its speed (time compression), you will also get pitch change. So a speed of 50% will drop pitch down an octave.

SAMPLER (DSP7500 & ORVILLE) : The module is capable of recording and playing mono or stereo samples with varying pitch and time scale. Up to 16 sound samples may be stored in memory so that various drum hits or vocal takes can be easily accessed. You can loop a sample, step thru multiple samples on successive triggers, and trigger the sample from audio.

To begin recording, trigger the record input. Recording will begin immediately and will continue until stop is triggered or all memory is used up. Another way to begin record is to trigger the triggered record. Recording will start when audio exceeds record threshold.

There is a pre-trigger capture, causing a small section of audio preceding the trigger event to be recorded. For each new recording, the audio is stored into a new sample location. This can be done until all the available memory is used up. A trigger to play causes the current sample to be played until the stop or pause inputs are triggered or the stop time is reached. You can have an audio signal trigger the playback by triggering triggered play. The particular sample to be played back is controlled by the play select control.

After recording, this control will be automatically set to the new sample. If a new play trigger is received while the current sample is playing, the new sample will begin playing immediately. The old sample will continue playing for the length of time set in the overlap control. By changing the nextplaymode setting, the playback can step through consecutive samples.

The samples to be stepped through are controlled by the playmin and playmax controls. If looping is set to enabled, the sample will automatically repeat, and the end of the sample will be crossfaded to the beginning. Change start and stop to single out what part of the sample you want. If start is after stop the sample will be played in reverse. When adjusting, you have a choice of either a tape recorder scrub emulation, or pitchscrub mode where the sound at the point will be played looped. Fadein and fadeout allow you to adjust how the sound is turned off and on. Use pitchamt to adjust the pitch of the sample and timeamt to adjust how fast the sample is played back.

This module allows real time editing of samples:

x-fading-looping-reverse-start & end points-time compression & expansion-pitch shifting-modulation of all its parameters.

The new OS, version 3.0, features System Tempo and Timer w/T_Delay, T_Rate and T_Decay parameters that allow all delays times/lfos rates/reverbs decays to be synced to tap tempo, according to rhythmic subdivisions. You can use absolute time (milliseconds) or rhythmic values. Long Delay modules take advantage of system Timer w/bars multiply.

Let me go thru Orville looping presets (Bank 7 : Delays - Loops), trying to explain what these presets do.

FRACTAL VORTEX
A recreation of Vortex dynamic layering of loops: Cascade looper with envelope control of the looper's input mix. Its output is fed into a panner which sprays the effect into a stereo glide, fed also directly by dry input. Envelope bias adjusts sensitivity of modulation for the input/feedback mix of the looper. Loud signals add new audio to loop, decreasing level of old layers. Soft signals keep both in the loop.
Echo balance : when set at min, the mix is all Echo 1, at max. it's all Echo 2. In between settings produce echo rhythm that change over time.

These presets are ALL included in Orville OS V3.0 ; most of them are also included in DSP7500 OS V3.0, obviously in stereo format. No Quad is possibleon the DSP series.

A Legacy of older Looping presets from the discontinued GTR4000, DSP4500 and from Presets Cards like the Alchemy 101 is also available on Pcmcia flash cards.

All 4000s can share these presets. Some presets of the DSP4500 will require to install the sampling board on a 4000 to run.

From the GTR4000: This unit had 10.5 sec delay. Its memory can be expanded by adding the sampling board. 2 boards are available to expand all 4000 series

The massive power of DSP7000/7500 and ORVILLE allows to combine looping AND fx in the same preset:

Distortion, bit dequantizing, eq, all sort of modulation fx, ring modulators, pitch shifting, reverb, delay, modulatable filters, panning, compression, expansion, poly-fuzzes, multiband distortion, synths, tone generators and many more fx can be combined in big patches.

ORVILLE also allows massive looping/sampling and processing, thanks to its dual DSP structure. You could run two of those described presets at the same time on Orville, choosing your èpreferred routings between in/out and DSPs.

VSIGFILE is definitely the tool on which any user can build his/her own personal variations of these presets or complately new structures.

ECLIPSE
24bit/up to 96KHz STEREO units, w/2 analog ins/outs, AES-EBU, S/PDIF and OPTICAL/ADAT in/out.

2 rear panel inputs that can accept 1 pedal or up to 3 footswitches EACH for parameters real time control.

MIDI protocol is fully supported. All parameters can be modulated by midi cc, notes, pedals, switches, audio input.

The unit is a dual engine processor: Eventide provides a collection of about 100 algorithms that can be combined in pairs in the 2 FX Blocks, choosing your preferred routing.

Looping:
Eclipse Engines have 20 seconds delay memory each. Looping is delay based, like in Orville/DSP series.

Algorithms useful for looping are:

• all multi-voice delay algorithms: they have 4 ddl lines (often combined w/modulation or filtering or resonators or ring modulators), w/2 sec delay time each- Useful for Tap Tempo multi tap looping.
  Up to 8 voices can be obtained by combinig two algorithms in parallel.
• Loop10: Mono 10 sec looping delay
• Loop20: Mono 20 sec looping delay
• Dual Loop5: Stereo 5 sec looping delays
• Dual Loop10: Stereo 10 sec looping delays
• Mono Reverse20: Mono 20 sec reverse delay
• Mono Reverse10: Mono 10 sec reverse delay
• Dual Reverse 10: Stereo 10 sec reverse delay
• Dual Reverse 5 : Stereo 5 sec reverse delay
• Ultratap 2: a popular Eventide H3000 structure contains four serial two-second diffusors feeding a 36 tap, two-second multitap delay and a tempo-controlled two-second feedback delay.
• T_Delay4 Plex:This plex has four two second tempo delay lines with 'level' and 'pan' parameters for each independent output.
• Reverse Crystals: two five second reverse shifters where the feedback signal can be the sum of the outputs, the channel output or the other channel for 'crisscross' effects.
• T_Delay_Diffchorus: This is a three tap delay (left, right and feedback-max 2 sec delay each) and a stereo diffchorus.
• Manifold Alpha: This is a pitch-shifting loop(up to 16 seconds) and slap delay. A mixer at the shifter input selects between the source and the loop signals, while another mixer at the loop input selects between the source and the shifted signals.
  Both outputs (pitch and loop) are then mixed with the left input (channel #1) and fed to the slap delay output on the left side, while the loop and pitch also get fed directly to the right output. Tempo may be used to control delay as well as loop and slap length.
• Manifold Beta: This algorithm is essentially a version of "manifold alpha," but it uses a reverse shifter (16 sec) rather than the normal (forward) pitch shifter.
• Reverse+Dly+Reverb: This is a reverseshifter (max 5 sec) into a three tap delay (left right and feedback-max 5 sec for each tap) and a reverb 8.
  
  

Most of these presets can be loaded twice in the same algorithm or combined with distortion, eq, all sort of modulation fx, ring modulators, pitch shifting, reverb, delay, modulatable filters, panning, compression, expansion, poly-fuzzes, multiband distortion.

Eclipse is a closed platform. The end user can't build algorithms from scratch. It doesn't have sampling expansion.
