E-MU Digital Audio System Driver 2.1
Date:  5/16/2008
Size:  34.2 MB

Before you download:
This Driver Package can either fully install Digital Audio System device drivers, or it can update an existing installation. It does not require that you had previously installed software from an original Digital Audio System CD, only that your system meets the minimum hardware requirements.

If you are installing this package on a system where you did not previously install Digital Audio System software, you must also install the latest version of Microsoft DirectX, which is available at http://www.microsoft.com/directx

If you already have Digital Audio System software installed on your computer, please take a moment to check the ABOUT BOX in PatchMix DSP (Right-click on the E-MU Logo right above the TV in PatchMix) to see if this update is necessary. If the version numbers below are higher than what you see in the About Box, you should proceed with the update.

Before you install:
If you have experienced a fault in any audio application, you should reboot Windows before applying this update.

Exit all applications before installing these updates.

After you install:
1616 and 1616M Users: Immediately after installing this upgrade, please be sure to turn the MicroDock off and then back on again, in order for the new firmware to take effect

Driver Package V2.1 contains the following feature enhancements and fixes:

Windows Vista - Fixes a "memory leak" bug in PatchMix in which PatchMix would continue to use, and fail to release system RAM.

Fixes a typo in the Insert Send list when using sample rates of 88.2 kHz and higher.

Fixes a rare bug on some computer systems where distortion occurs when using WDM at sample rates of 88.2 kHz and above.

Includes changes from V2.00 Release

Windows Driver Signature
When you install the Digital Audio System drivers, you will see a dialog box informing you either that the driver has not been certified by Windows Hardware Quality Labs (WHQL), or that the driver is signed by Creative Labs, Inc, and you will be asked if you would like to continue with the installation.

The Digital Audio System audio drivers are not certified by WHQL because the product does not support some of the features that the Microsoft Windows Logo Program requires, most notably Universal Audio Architecture (UAA) and Digital Rights Management (DRM).

Despite this, the Digital Audio System audio drivers have been rigorously tested using the same test procedures that a WHQL qualified driver requires, and it passes in all of the other important categories, including those that measure the relative stability of the driver. So, it is perfectly safe to install these drivers on your computer.

  • E-MU® 0404 PCI, 1616 PCI, 1616M PCI, 1212M, 1616, 1616M, 1820, 1820M Digital Audio System, or Emulator® X, Emulator® X Studio Desktop Sampling System, or Proteus® X Desktop Sound Module.
Driver Revision History

Changes from V2.00 Release:
  • Added Windows Vista support
  • Added support for 1616 PCI, 1616M PCI
  • Added new Core effects (see PatchMix 2.00 app notes for details)
Fixes:Includes changes from V1.82 Release.
Changes from V1.82 Release:
  • Improved audio quality of ASIO driver record and playback when used at low latencies.
Includes changes from V1.81 Release.
Changes from V1.81 Release:
  • Installer now fully installs Digital Audio System drivers on any machine that meets minimum hardware requirements, including those that do not have previous Digital Audio System software installed.
  • Added 88.2 kHz and 176.4 kHz support to products using E-MU 0404, 1212M, 1820 and 1820M PCI hardware. (NOTE: Also requires PatchMix DSP V1.81 or later)
  • Added support for up to 8 channels of audio playback through the E-DSP Wave device. This allows the digital audio system to play certain types of multi-channel content (WAVE_FORMAT_EXTENSIBLE format) (NOTE: Also requires PatchMix DSP V1.81 or later)
  • Changed buffer latency selection choices in the ASIO Control Panel to offer more granularity at lower latencies
  • Fixed bug where hardware latency values displayed in certain ASIO applications (such as Cubase SX 3 and Nuendo) were not accurate.
  • Fixed bug where Audio Dock would sometimes not power up properly on a system boot.
Changes from V1.8 Release:
  • Improved ASIO / WDM recording performance during bursts in PCI bus activity, in order to eliminate recording dropouts
  • Improved ASIO driver behavior when used with Sonar
  • ASIO driver now fully recovers after an ASIO application crashes or is abnormally terminated
  • Improves PCI performance by automatically setting optimal PCI Latency values for the DAS hardware
  • Improved efficiency of PCI bus utilization, to allow for better recording performance on systems with other PCI-intensive devices (such as Effect Accelerators, SATA hard disk drives)
  • Fixed bug where Cubase SX would not accept sample rate changes from PatchMix DSP
  • Fixed bug where Sonar would crash when using ASIO at a sample rate that was not the same as PatchMix DSP
  • Fixed a bug introduced in driver V1.71 affecting 1212m, 1820 and 1820m, where symptoms may include AudioDock not responding correctly and External Clock not functioning
Includes changes from V1.71 Release.
