OVERVIEW AND QUICKSTART
THE BIG PICTURE
The Eventide Orville is a programmable, multichannel, multipurpose, dual digital signal processor (DSP), 24
bit digital audio signal processor with UltraShifter capability. That’s a lot of adjectives! It is the successor
to a long, proud line of digital signal processors that stretches back to a time when most audio manufactur-
ers didn’t know digital audio from Morse code.
Orville is loaded with features that put it in a class by itself. It has four analog inputs, four analog outputs,
four digital inputs, and four digital outputs that can all be used simultaneously. Routing among them is com-
pletely flexible (“anything to anything”)! What’s more, Orville houses two independent signal processors,
each having four inputs and four outputs (imaginatively dubbed “DSP A” and “DSP B”). The two proces-
sors can be run in parallel, in series, or in any mutant variation thereof.
The variety and depth of the programs that run on the DSPs are truly amazing, from lush reverbs, to cho-
ruses, to flanges, to delays, to pitch shifters, to dynamics, to EQs, to filters, to distortions, to synthesizers, to
samplers, to ring modulators, and everything in-between. Most frequency and time-dependent parameters
(e.g. delays, LFO's) synchronize to a system tempo for ease of use. And if that’s not enough, DSP A boasts
nearly three minutes of sample time in addition to the 40 seconds of delay time found on both DSP A and
DSP B!
And for the user who is interested in making his or her own programs (if the huge number of factory pro-
grams aren’t enough!), Orville continues the “modular programming paradigm” that made the DSP4000
famous. Programs are composed of individual building blocks, or “modules,” that allow the user to create
original programs. Inspiration and creativity are given no bounds. . .
As you read this manual, it may be easy to “lose sight of the forest for the trees.” Always bear in mind the
following:
• Orville houses two independently running DSPs (digital signal processors). They are lovingly referred to
as “DSP A” and “DSP B.” Although they are both always running, you can only view the parameters for
one DSP at a time. Use the DSP A/B key to toggle the display between the two DSPs.
• Each DSP runs “programs” that are stored in the system. “Programs” are the algorithms that manipu-
late your audio. With the exception of “large sampler programs” and some “long delay” programs, any
program can be run on either DSP. Like two separate effects boxes, the parameters for the program
running on DSP A are totally independent of the parameters for the program running on DSP B. Like
two separate effects boxes, you can connect the outputs of one DSP to the inputs of the other, or use
them completely independently.
• Orville has four analog inputs, four analog outputs, four digital inputs, and four digital outputs that can
all be used simultaneously. DSP A has four inputs and four outputs, and DSP B has four inputs and four
outputs. Any input can be connected to any output. It’s that simple (conceptually)!
