A bank can hold up to 1000 presets.

Indicates first digit is locked at 0

v To Lock the first digit of the two digit Bookmark Number:

•Press and hold the Lock button (located to the left of the numeric buttons) while pressing one of the numeric buttons to lock the most significant digit.

•Press the Lock button by itself to turn Lock mode On or Off. The lock indicator on the display is shown in the previous illustration.

With Lock Off, two digits must be entered to select a bookmark. For example, to select bookmark 9, you would press 0, then 9.

With the most significant digit locked, only one button press is required to select a bookmark.

v To Select another Rank of 10 Bookmarks:

•Press and hold the Lock button and press one of the numeric buttons. The display informs you of which rank of 10 bookmarks is now selected.

The Bank

The bank contains samples, voices, presets and sequences. Everything that is loaded into the Emulator is part of the bank. Although the memory is volatile, meaning that the data disappears when you turn off power, all bank data can be saved permanently to a hard disk drive or other media. The number of samples that can be loaded into a bank at once is dependent on the amount of sample RAM you have installed in your Emulator.

Folders

Just like on a computer, folders help keep banks organized. A folder can contain up to 100 banks (0-99). You can use folders to organize your sound banks by including all the banks used for a particular project in a folder. The number of folders in a disk depends on the size of the disk. As an example, a one gigabyte hard disk can hold up to 96 folders.

The Internal Drive

A disk drive is a memory storage device that stores banks of data. The floppy drive is used mainly to update the operating system software. (The operating system consists of the instructions that tell the Emulator what to do.) Other types of disk drives, as described below, can connect to the Emulator to provide efficient sound storage.

Floppy Disk Drive: The floppy disk drive requires 3.5", double-sided, high-density (1.4 MB) floppy disks. As new enhancements are developed, the new software is distributed on floppy disks. The floppy drive is used to update the operating system software. This software can be copied into Flash RAM and made a permanent part of the Emulator itself.

It is also ideal for transferring sequences to and from a computer-based sequencer. With large bank sizes of 4-128 MB, the floppy disk becomes impractical for backing up sound data, although it can be used to save or transfer small sound banks in a pinch.

EOS accepts 2 kinds of floppy formats. DOS formatted disks allow multiple files per disk and are compatible with PC and Macintosh computers. EOS formatted disks allow one bank to be spread over multiple disks.

Note: The Emulator can format floppies in EOS format only. DOS floppies must be formatted on a PC or Mac computer or purchased preformatted. EOS cannot read Macintosh floppies, but fortunately the Mac can read and format DOS floppy disks.

To Update the EOS Software:

Since the EOS operating system is stored in Flash ROM, it can be easily updated to add features or to fix bugs. The following procedure explains how.

1.Turn off power.

2.Insert the floppy disk into the drive.

3.Turn on power.

4.Press Enter to update or Exit to cancel.

5.Wait for the Emulator to update its firmware.

6.Re-initialize EEPROM. (This should be done after a software update to “clean the slate”. It resets the Master menu preferences and other bits.)

a.Press Master

b.Press Utils

c.Press Tests

d.Enter the Secret Password: 1-3-5-8, then press OK.

e.Press More

f.Press InitEE The display reads, “Initialize EE?”

g.Press OK. The display reads, “Saving System”

f. Press Master to exit diagnostics mode.

7.Recalibrate the Emulator controls. See “Recalibration” on page 68.

O Use the “Mount Drives” utility whenever an external SCSI device does not appear in the display.

Internal Hard Disk Drive: A hard disk provides the advantages of much higher memory capacity and far faster access time than floppy disks. However, the hard disk cannot be removed and its data must be backed up to another medium for safekeeping.

IDE Drives: The Ultra series Emulators can make use of an internal IDE hard disk. An IDE drive has several advantages including: low cost, high capacity, low noise and it doesn’t use up a precious SCSI ID number. Order IDE installation kit #6303. This includes everything needed except the IDE drive.

External Drives

Emulators are equipped with SCSI (Small Computer Systems Interface) connector(s) on the rear panel. This interface is commonly used in the computer industry, so many devices made to work with computers—partic- ularly mass storage devices—will also work with Emulators. Here are some of the types of mass storage devices that can be connected to the Emulator using the SCSI connectors.

Hard Disk Drive: A hard disk provides the advantages of high memory capacity and fast access time. Transferring data is quite straightforward. However, you cannot remove a hard disk and replace it with another one— the disk is a permanent part of the drive. There are some important cautions involved with hard disks:

1.Hard disks are sensitive to extreme mechanical shocks. If your hard disk falls off a keyboard stand, chances are the hard disk will be damaged.

2.Hard disks have reached a very high level of reliability. However, they can fail from time to time (as can any part of a computer), so any data should be backed up periodically on some other medium.

Removable-media Hard Disk Drives: These are similar to standard hard disk drives except that the disk itself can be removed and replaced with another disk (similar to floppy disks). Disk densities can range from 44MB to well over 1 Gigabyte (GB) per platter. Removable-media hard disk drives make it easy for you to build a sound library of unlimited size and are quite handy for transferring sounds between machines. They’re also perfect for backups because you can remove the media and keep it in a safe place.

CD-ROM Drive: A CD-ROM is a playback-only mass storage memory device whose capacity is approximately 660MB. Quality CD-ROM libraries are available from several companies (E-mu Systems, InVision, Northstar, Q-Up Arts and many others). These can be loaded into the bank just like a hard disk.

Magneto-Optical Drive: These high speed, high density storage devices are ideal for storing large amounts of sound data. Typically a magnetooptical drive can hold upwards of 300 MB per side and the removable cartridges can be used over and over. Disk access time is comparable to a normal hard disk. Although you can read and write to these drives, they are generally slower than most hard disks.

O The Memory Configuration control (Master, Setup, Memory), allows you to balance the allocation of Preset Memory between the Sequencer and Presets.

Contact your E-mu dealer if you wish to upgrade your CPU RAM.

Preset Flash can also be used to store presets for HD based sound banks. However, this can be confusing since the proper samples may not be loaded into Sample RAM when the preset is selected.

1 - The Basics

Sound ROM & Sound RAM

Sample Memory & Preset Memory

EOS presets use two separate memory locations — Preset Memory and Sample Memory. Preset memory (also called CPU memory) is used to hold both preset parameter information and sequences. (The ratio between presets & sequences is user adjustable — see sidebar tip.) The amount of Preset Memory determines the number of presets and sequences you can have in your Emulator.

Preset memory on the e-64, E-IV, E4K, and E-6400 is about half a megabyte. The E4X, and E-Synth come standard with 2.6 MB of usable preset memory. Ultra models have about 4 MB of preset memory. Sample memory contains the actual sample data and can vary from 4 MB to 128 MB. Because presets use far less memory than do samples, less preset memory is needed.

Sound ROM & Sound RAM

Sound ROM is a standard feature on E-Synth and one of the available hardware upgrades for other EOS instruments. Although the samples themselves are in ROM and cannot be changed or modified, the Presets with all their keyboard mapping and synthesizer parameters can be changed because they are stored in non-volatile Preset Flash RAM. Flash RAM contain 256 to 1000 presets depending on the amount of Flash RAM you have installed. Flash presets are located immediately after RAM preset 999 (I000 - IXXX) in the preset numbering scheme.

Five Types of Memory

The Emulator uses up to five different memory types. It CAN be confusing.

•Sample RAM - 4-128 MB. Contains samples loaded from the hard disk.

•Sample ROM - Permanent ROM samples. Optional on all but E-Synth.

•Preset RAM - 1-8 MB of dynamic RAM. Used by CPU, and also contains presets and sequences loaded from the hard disk.

•CPU Flash - Normally used to store presets for ROM or S-Flash banks.

•Sound Flash - Optional flash SOUND memory to store your own banks.
