UAD-1 Support

About UAD-1 End Of Support (EOS)

Notice to UAD-1 Users

November 8, 2013

As of December 31, 2013, Universal Audio has shut down the UAD-1 registration / authorization servers and related UAD-1 card transfer functions. We have also discontinued 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.


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 Minimum System Requirements (UAD v6.1.0)


    • Microsoft Windows XP (Home, Professional, or x64 Edition), Windows Server 2003, Windows Vista


    • Mac OS X 10.5 Leopard, 10.6 Snow Leopard, or 10.7 Lion
    • Processor upgrade cards are not officially supported

All Platforms

  • Available PCIe slot (x1/x4/x8/x16) for each UAD-1e card
  • Available PCI or PCI-X slot for each UAD-1 card
  • ExpressCard/34 or ExpressCard/54 expansion slot for each UAD-1 Xpander
  • 512 MB RAM (1 GB or higher is strongly recommended)
  • 600 MB available hard drive space
  • 1024 x 768 or higher resolution display monitor
  • Internet connection to download software and authorize UAD plug-ins
  • Compatible VST, RTAS, or Audio Units plug-in host application software
  • AGP or PCIe graphics video adapter card (PCI graphics not supported)

Note: Older UAD software is available for use with earlier operating systems in the UAD software archives.




UAD-1 Documentation

About UAD-1 Documentation

  • Complete documentation for all UAD-1 devices is included in the UAD v6.1 Manual. The UAD v6.1 Manual is placed on the hard disk during UAD software installation. You can also download the manual directly from the UA website.


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.   UAD Software Archive



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

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


  • (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.




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.

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.

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.

  • All measurements are taken at a sample rate of 44.1 kHz.
  • DSP savings and higher instance counts can be achieved with plug-ins marked with an asterisk ( * ) by turning off sections of the processor. See the UAD Plug-Ins Manual for details.
