Overviews, Basic Information, and Quickstart
You’ve bought a serious piece of machinery, friend. A beneficiary of Eventide’s venerated Orville and
H3000 line of effects processors and a quarter century of Eventide’s digital audio excellence, the Eclipse
boasts…
 The world’s richest sounding and widest array of effects
 A global tempo feature that synchronizes LFOs, delay times, and other time-sensitive parameters to
the music being processed
 Two configurable effects blocks for serial, parallel, or dual-mono processing
 An arsenal of LFOs, envelope followers, and ADSRs that can be patched to any parameter
 Analog and AES/EBU, S/P DIF, optical, and ADAT digital inputs and outputs for total flexibility
 24bit resolution for superb fidelity at up to 96kHz sampling
 MIDI control of parameters for inspired creativity
Read on to learn how to put all this muscle to use...
The Big Picture – A Must-Read
The Eclipse is conceptually simple. At any given time:
 A “program” is loaded. Programs such as delays, reverbs, and pitch shifters (among many others) do
the effecting.
 A “tempo” is running unless turned off. The Eclipse derives the tempo from a sequencer connected to
its MIDI In port or from the front panel TAP key (there are a few other ways to set the tempo). Many parame-
ters such as LFO rates and delay times change to synchronize with the tempo.
 A “modulation block” is modulating. The modulation block contains LFOs, envelope followers, etc.,
that exist independently and in addition to any LFOs, envelope followers, etc., that are constituents of
programs. You can patch parameters from programs to these LFOs, envelope followers, etc.
 A suite of “global parameters” defines the Eclipse’s overall behavior. Global parameters are such
things as input and output levels, digital audio speeds and protocols, MIDI channels, and so on.
You load and save programs with the PROGRAM key, and a program’s most important parameters are lo-
cated under the
HOT KEYS key. A program contains two “effects blocks” and the routing between them
(series, parallel, etc.) is accessible with the PARAMETER key (some programs only use one of the two available
effects blocks)
. An “effects block” runs one of the Eclipse’s core set of “algorithms.” The algorithms are de-
scribed in the separately provided “Eclipse Algorithms” document. Put another way:
 A program, such as Desert Gtr contains one or two effects blocks
and the routing between them (series, parallel, etc.).
 An effects block runs an “algorithm,” such as
polydriver or diff-
chorus
.
 You load and save programs under the PROGRAM key.
 You alter the routing between effects blocks and the parameters of
each effects block under the PARAMETER key.
When it comes to routing signals inside the Eclipse, it’s helpful to think of the effects blocks and the rout-
ing between them as existing within the “DSP.”
