Notice to UAD-1 Users

November 8, 2013

As of December 31, 2013, we will be shutting down the UAD-1 registration / authorization servers and related UAD-1 card transfer functions. We will also be discontinuing the sale of UAD-1 plug-ins in our online store.

UA has not introduced a new UAD-1 plug-in since 2009; and our planned deactivation of the 12-year old UAD-1 servers is a necessary step for us to move the UAD platform forward into 2014 and beyond.

Please note that, in every other way, your UAD-1 card and plug-ins will continue to work exactly as they always have. After December 31st, you will still be able to download your final UAD-1 authorization file, but you will not be able to make any changes to it — including adding plug-ins and/or transferring card ownership.

About UAD-1 End Of Support (EOS)

Definition of UAD-1 EOS

Service and support for all UAD-1 hardware and software was discontinued on January 1, 2014. The EOS includes all UAD-1 devices (UAD-1, UAD-1e, and UAD-Xpander).

As of January 1, 2014, all UAD-1 accounts were frozen in their final state, the UAD-1 authorization servers were decommissioned, and it is no longer possible to:

  • Register a UAD-1 device
  • Purchase UAD-1 plug-ins
  • Transfer UAD-1 devices between user accounts
  • Obtain factory repair or replacement of UAD-1 hardware (including parts)

It is still possible to:

  • Use your UAD-1 device with UAD v6.1 or lower software
  • Download your final (static) UAD-1 authorization file
  • Use your UAD-1 with UAD-2 devices in a mixed system (UAD v6.1 or lower only)
  • Cross-grade your UAD-1 licenses to UAD-2 licenses at no charge

UAD-1 Authorization

About UAD-1 authorization

  • UAD-1 plug-in licenses are activated on a particular computer system by loading the UAD-1 authorization file associated with that device's hardware identification number. Important: UAD authorization files and UAD devices are a matched set; an authorization file will only work with the UAD device associated with the file.
  • The UAD-1 authorization file must be reloaded whenever the UAD-1 device is moved to a different computer system (this differs from UAD-2 devices, which store UAD authorizations on the UAD-2 device itself).
  • After successful UAD software and hardware installation, UAD authorization files are loaded by simply double-clicking the file on the system containing the UAD device.

Obtaining UAD-1 authorization files

  • UAD authorization files for particular UAD devices can only be downloaded by the registered user of the account that contains the UAD device.
  • Upon UAD-1 EOS, the state of the UAD-1 account will be frozen, and a final UAD-1 authorization file will be generated for the device(s). This final UAD-1 authorization file will be stored on UA's servers and will continue to be available for download by the account holder, but it will no longer be dynamically generated by the authorization servers.
  • Transferring UAD-1 devices to a different user

    • After UAD-1 EOS, if a UAD-1 device is sold or otherwise transferred to a different user, the UAD-1 plug-in licenses associated with the UAD-1 device cannot be transferred to the new user.
    • Important: After UAD-1 EOS, the service of transferring a UAD-1 device to a different owner will no longer be provided by UA customer support.

    UAD-1 Software

    Latest UAD-1 Software

    • The most recent version of UAD Powered Plug-Ins software for all UAD-1 devices is UAD v6.1.0. Versions higher than 6.1.0 do not work with UAD-1 devices.
    • Older versions of UAD-1 software are available in the UAD software archives. Archived software is provided for use with earlier operating systems.
    • Direct download links to UAD v6.1.0 software

    General UAD-1 Information

      UAD-1 versus UAD-1e

    • On this page, all references to "UAD-1" apply to all UAD-1 device types (UAD-1, UAD-1e, UAD-Xpander) unless specifically noted otherwise.
    • UAD-1 cards can be used in PCI or PCI-X slots only.
    • UAD-1e cards can be used in PCI Express (also known as PCIe) slots only.
    • PCI and PCI-X are different than PCI Express. PCIe devices are not compatible with PCI or PCI-X slots because PCIe uses a completely different connector.
    • UAD-1 instance counts

    • The UAD-1 Instance Chart shows how many of each UAD plug-in can be loaded on a UAD-1 device.
    • 64-bit operation

    • (All) UAD-1 Powered Plug-Ins are 32-bit only.
    • (Mac) Device drivers for UAD-1 are 32-bit only.
    • (Win) Device drivers for UAD-1 are 32-bit and 64-bit.

    Troubleshooting UAD-1

      Complete Uninstall/Reinstall Procedures

    • Uninstall/Reinstall for Mac
    • Uninstall/Reinstall for Windows
    • Mac

    • (Mac Pro) Some users have experienced problems with Apple Mac Pro computers and Logic Pro 8 when used with UAD Powered Plug-Ins. The problems manifest as CPU spiking, and occasional halting of playback, and symptoms seem to occur more often on the 8-core model. We have determined that this problem stems from the unique way in which Logic Pro 8 treats plug-ins on a track with no audio currently passing through it. There is no definitive solution. Other hosts besides Logic 8 work fine with UAD-1e on the Mac Pro models, including the 8-core. We do not recommend using UAD-1e or UAD-1 with this specific CPU/DAW configuration.


      About UAD-Xpander

    • UAD-Xpander was the world's first ExpressCard audio DSP expansion system for Mac OS X and Windows Vista notebook computers.
    • The UAD–Xpander has identical DSP power as the UAD-1 series of desktop products.
    • Complete documentation for the UAD-Xpander is included in chapter 10 of the UAD v6.1 Manual.
    • This section contains UAD-Xpander support information that is not included in the manual.
    • All Platforms

    • Install the UAD Powered Plug-Ins software before connecting the Xpander hardware.
    • The Xpander hardware must be connected and powered up before booting the computer.
    • Do not remove the UAD ExpressCard or UAD Link Cable, or power down the Xpander while the Xpander is connected to an active computer unless no UAD clients are running and the ExpressCard is properly powered down. Alternately, simply power down the computer before disconnecting the Xpander.
    • If the computer is active and no UAD clients are running, the UAD ExpressCard may be safely removed after powering it down by selecting "Safely Remove Hardware" (Windows Task Bar) or "Power off Card" (Macintosh Menu Bar) before removing it. However, the computer must be rebooted with the Xpander connected in order for the hardware to be recognized again.
    • The UAD ExpressCard/34 may be used in an ExpressCard/54 slot.
    • Windows

    • UAD-Xpander runs on windows notebook computers under Windows Vista only (Windows XP does not work with UAD-Xpander on notebook computers).
    • UAD-Xpander can be used under Windows XP only on PCIe desktop systems via the UAD-Xtenda adapter (which is no longer available).
    • System Sleep is not supported when using UAD-Xpander under Windows. System Sleep should be disabled while the UAD-Xpander is connected.
      • To disable Sleep in Windows: In Control Panel>Performance and Maintenance>Power Options>Power Scheme panel, set the Power Scheme to "Always On”
      • To disable Sleep in when notebook lid is closed: In Control Panel>Performance and Maintenance>Power Options, click the "Change when the computer sleeps" option on the left side of the screen, then select "Never"


    • Some prior "unibody" MacBook Pro systems (e.g., MB470LL/A, MB471LL/A, MB604LL/A) did not support UAD-Xpander with RAM configurations greater than 4GB. This issue is resolved with the latest MacBook Pro firmware available from Apple.
    • System Sleep works under Mac OS X. If the machine is put to sleep with the transport running, the UAD plug-ins will typically be disabled several seconds before audio stops. Therefore, a change in the audio may be noticed. Similarly, when the system is awakened, it may take several seconds for the UAD plug-ins to be reinitialized.
    • Additional Information

    • The UAD-Xpander requires UAD v4.7.1 or higher (UAD v5.0.0 or higher is recommended for enhanced ease of use).
    • UAD-Xpander cannot be used with desktop computers that have only PCI or PCI-X slots because there is no PCI or PCI-X ExpressCard adapter available.
    • The ExpressCard slot on notebook computers is non-latching, so it is possible to accidentally pull the card out.
    • Do not bend sharp angles into or otherwise kink the UAD link cable. The cable has a ferrite core and multiple conductors that could be damaged by improper handling.
    • The UAD-Xpander contains a UAD-1e card that looks similar to the UAD-1e model for desktop computers. However, the cards are not the same. Do not attempt to install a UAD-Xpander card into a computer slot, or put a UAD-1e into the Xpander chassis. Doing so will damage the cards and/or the computer logic board.
    • The PCIe-based UAD-Xtenda was a PCIe to ExpressCard Adapter which enables the UAD-Xpander to also be used on a desktop Mac or PC like any other UAD-1 device.

    UAD-1 FAQ

    Can I use the UAD-1 with Pro Tools?

    Yes. UAD v6.1.0 includes RTAS versions of UAD plug-ins for compatibility with Pro Tools. For the latest Pro Tools support information, see the Pro Tools support page.

    Does UAD-1 support sleep mode with UAD v6.1.0 software? 

    System sleep is not recommended. Although many customer report no issues, some customers have reported that their computer will crash when waking from sleep after installing v5.0 or higher. So our general advice for users who have a UAD-1 card in their system is to set sleep mode to "Never."

    Can I run my current host-based (native) plug-ins on the UAD-1?

    No, only UAD Powered Plug-Ins can run on the UAD-1 card. You can run your favorite native plug-ins on the host system concurrently with UAD Powered Plug-Ins running on the UAD-1 card. UAD Powered Plug-Ins will appear in your host application just like standard native plug-ins.

    Can Mac OS 9 be used?

    UAD Powered Plug-ins runs under Mac OS 9 in version 3.9.0, which is available in the UAD archives.

    Are UAD-1 products available for purchase?

    No, the UAD-1 product line was discontinued in June 2009. Thanks to all our customers for your ongoing support.

    Can multiple UAD-1 devices be used?

    Yes, the UAD software (v6.1 or lower) allows multicard use under Windows and Macintosh. Up to four UAD-1/1e cards plus four UAD-2 cards can be used, for a total of 8 UAD cards, within one system.

    Why can't I see the UAD plug-ins I obtained from the UA store in my host application, even though I loaded the new Authorization file?

    Prior versions of the UAD software bundle may not include the most recent plug-ins. Install the UAD v6.1.0 software to ensure you have all available plug-ins. UAD v6.1.0 download links: Mac | Windows

    How many UAD-1 plug-ins can I run simultaneously?

    There are countless combinations. See the UAD-1 Instance Chart for more detail.

    Can the UAD run alongside other DSP cards (e.g. TC PowerCore, Creamware Pulsar, etc.)?

    Yes. Many users have reported success using the TC PowerCore, Korg OASYS, Creamware DSP, and Yamaha DSP Factory cards concurrently with UAD Powered Plug-Ins. The UAD card is fully compliant with the PCI 2.1 specification.

    What is the Mackie UAD-1 card?

    The UAD-1 card was originally distributed by Mackie as an OEM product. It was designed, manufactured, and supported by Universal Audio. The hardware is identical to UAD-1 cards that are UA-branded.
