Introduction

This is the operation manual for E-mu Operating System (EOS). EOS is the operating system in several E-mu products, including: E-IV, e-64, E4K, E-6400, E4X, E-Synth and the E4 Ultra series. The same EOS software is loaded into each of these machines. For the sake of simplicity, we refer to all these products as “the Emulator” when we talk about them in this manual (unless, of course, there is an issue involving a particular product, then we will be specific).

Your Emulator is a special purpose sound computer and like all computers, can be thought of as having two main components:

1.The physical machine with the buttons, keys, gadgets, that generates sound and;

2.The EOS software that tells the hardware what to do.

This manual describes how to use EOS to get the most from your Emulator. The various functions of EOS are organized in this manual by their module. Screen displays and step-by-step instructions are described for all aspects of use and operation. Notes in the margin highlight important points or give useful operational tips which might not be readily apparent.

If you are unfamiliar with samplers and synthesizers in general, you may need more information than this manual provides. We suggest that you read some of the many books and magazines on the subject of music synthesis. This will help you to get the most out of this extremely powerful instrument.

Important Upgrade Information

The features and functions of EOS are enhanced and upgraded periodically. Please take a moment now to read the E-mu Systems warranty and fill out and send in your warranty registration card. We NEED your mailing address in order to keep you informed about upgrades and manual revisions.
