Emulator IV, EOS

Overview The Emulator Operating System (EOS) did moved on leaps and bounds over the years. Here is a complete guide to all the versions, if possible upgrade to 4.10.

Version 4.7  “FAT” This software is the latest and was only released as a beta version. The and he major feature in this upgrade is the EOS FAT file system. EOS FAT is based on the FAT32 disk file system as used by Microsoft™ corporation and others. In addition, EOS FAT makes it much easier export files as .wav or .aiff and transfer files from your E4 and your PC or Mac.

Version 4.6 New Features in the EOS version 4.6 enable import Ensoniq ASR-10 and EPS sounds from CD or floppy.

EOS 4.62 ink Flash prep

Version 4.5  “R-Chip” This software was pre-announced in October 1999 when E-mu Systems released early details of the R-chip 32 bit FX processor card. This card and EOS 4.5 was debuted in a low key session at Winter NAMM 2000. It should ship in fall 2000, probably only with the new FX card. We will post more details on EOS 4.5 when we get them. For now you can read all about the R-Chip to get an idea of what EOS 4.5 is going to contain.

Beat Munging 2.0 will also be included, as well as a bug fix to EOS on the scrub wheel.

EOS Upgrade Advice

Overview All Emulator 4 and Ultra owners should upgrade to the latest EOS 4.10 for the best feature set and the least bugs.

4.10 Classic The owners of the original Emulator 4 range looked on as the fast new Ultras came out in early 1999. Whilst some of the later Emulator 4 models can be Ultracized, the next best option is upgrade to EOS 4.10 Classic. It provided all the 4.0 features (except Beat Munging) for owners of certain pre-Ultra Emulator 4’s, and a new CPU ROM. This is why it is called CLASSIC. If you have an Ultra you could also upgrade to 4.10 (non-Classic).

EOS 4.10 (not Classic) Ultra Owners could also upgrade to 4.10 as a straight sampler software upgrade. There is no EOS Link software (as you should have it already), and no need for a CPU ROM SIMM upgrade.

Big Flash EOS versions 4.01 and higher are so much bigger than the earlier releases of EOS that it needs more space in Flash (or CPU) ROM than is available in non Ultra Emulators. The existing 1MB SIMM needs to be replaced with a 2MB SIMM. This is ONLY available from E-mu Systems. It costs between $99 – $129 for the rack Emulators (depending on whether you already have the EOS link software). It comes with the latest 4.xx software. The E4K upgrades are much more expensive at up to $595. Check the E-mu Systems web site for details.If you have an Ultra, then you already have enough CPU ROM to run EOS 4.0+.

Bugs Life EOS 4.01 has bugs. E-mu Systems released EOS 4.02 in late 1999 to fix these. So you can only upgrade a pre-Ultra sampler to 4.02 or higher now. If you have 4.01, you should plan to move to 4.02 or 4.10 (however it can be tricky to install!).

EOS Link   The 4.01 Classic upgrade optionally includes the EOS Link software, if you need it.

The 4.10 release is useful if you have a Proteus 1000/2000 module. Here is the Sound Author manual.

  1. Just need to figure out how to get this update from PC to E64.

  2. It’s better to have an older PC that you equip with a SCSI card and a floppy. USB floppies don’t work with everything you throw at them [like Roland format] and they’re more expensive.

  3. My E4X still has 3.0 firmware…..can I update to 4.10 without trouble? Thanks…

    • Yes, you should be able to do it.
      You should then be able to upgrade to 4.10 classic
      Because of the E4X belongs to the classic family

  4. got any sound banks you could upload for this?

  5. Anyone who knows where I can download EOS 3.0b?

  6. It’s no problem, and you are absolutely right. However, a 1.44 MB disk may contain the EOS.

  7. none of the disk images fit on a floppy. they say they are 1.5meg and a floppy has just shy of that like 1.48meg so none of these images are able to be put on a floppy to be used.. thoughts anyone??

    • One of the installation disks indicates that it is 1.5 MB large, and should not fit on a standard 1.44 MB disk. However, when you start the .exe file, it will get it on a regular disk.
      … it may seem weird, but it works

  8. E4 with EOS 2.0b; is it possible to update the OS or am I stuck?

    • Yes, at least up to 3.0b and you have the OS on a floppy disk.

      • Thank you. So the 3.0b file that you have available is just the SDISK program and not the EOS system correct? I was able to create the other disks successfully with Windows, but 3.0b appears to be something else. Unfortunately, since my flash rom is 1mb, I can’t utilize those other EOS systems.

  9. I have install disks for 4.6 and 4.7 as well as flash prep. Only problem isn’t my emu esynth is at 4.02. So I can’t install them. Can’t I pay someone to put 4.1 on a floppy and mail it to me? I don’t have a PC and I’d rather just pay someone for the disk instead of trying to do it myself. Anyone out there that can help me?!?!!
