Introduction
Welcome!
Thank you for making the Alesis Akira™ a part
of your studio. Since 1984, we've been
designing and building creative tools for the
audio community. We believe in our products,
because we've heard the results that creative
people like you have achieved with them. One
of Alesis' goals is to make high-quality studio
equipment available to everyone, and this
Reference Manual is an important part of that.
After all, there's no point in making equipment
with all kinds of capabilities if no one explains
how to use them. So, we try to write our
manuals as carefully as we build our products.
The goal of this manual is to get you the
information you need as quickly as possible,
with a minimum of hassle. We hope we've
achieved that. If not, please drop us an email
and give us your suggestions on how we could
improve future editions of this manual.
We hope your investment will bring you many
years of creative enjoyment and help you
achieve your goals.
Sincerely,
The people of Alesis

Introduction
What You Can Do With Your Akira
When you have the Akira properly connected, you can:
o add space or “room sound” to dry or sterile sounds using
the Halls, Rooms and Reverse reverberators.
o generate echoes (multiple repeats) with different spectral
characteristics to your source with the Delay programs.
o create lively ensemble effects from a single instrument or
static section using the Chorus and Phasor programs.
o introduce classic warm, metallic sweeping effects that
simulate analog tape fluctuation using the Flange
programs.
o reproduce the classic guitar amp Tremolo effect on both
instruments and vocals.
o animate your instruments with an arcane synthesized edge
by applying the LFO-driven Filter effects and Ring
Modulator.
o shape the tone of your source material with several static
Filters in the spirit of vintage and modern modular
synthesizers.
o move your polite-sounding instruments and vocals into
aggressive territory using the palette of Distortion effects.
o add punch, warmth and character to your tracks with the
compressor – limiter effects.
o remove the vocal and other lead instruments from an
existing recording with the Vocal Eliminator program.

How to Use This Manual
This manual is divided into the following
sections describing the various functions and
applications for the Akira. While it's a good
idea to read through the entire manual once
carefully, those having general knowledge about
studio equipment should use the table of
contents to look up specific functions.
Chapter 1: Quick Start. If you're already
experienced with recording, this will get you
started using the Akira right away. It's a short
guide to the essential elements of hooking it up
and using it for the first time. A brief tour of
the front and back panels is included.
Chapter 2: Connection give detailed instructions
for connecting the Akira to a variety of typical
audio systems.
Chapter 3: Editing tells how you can easily edit
and store the three most important parameters
of each Akira program.
Chapter 4: Description of Programs gives you a
detailed explanation of each of the Akira’s 50
effects programs.
Chapter 5: MIDI. This chapter describes the
(M)usical (I)nstrument (D)igital (I)nterface
functionality of the Akira.
Chapter 6: Troubleshooting. Refer to this chapter if
you experience any problems while using the
Akira.
