If you are upgrading from version 1.x to 2.0.1, you gain the following massive features:
Why choose 2.0.1 over the original 2.0? Because the original 2.0 release had flaws. The 2.0.1 firmware specifically resolves:
Critical Note: The 2.0.1 firmware is the last official firmware released by Avid. There is no 2.0.2 or 3.0. If your unit is running any version below 2.0.1, you are missing both content and stability.
All Eleven Rack users on EP 2.0.0 should update to 2.0.1 for stability and additional tone options. Users on earlier firmware (1.x) must first purchase/install Expansion Pack 2.0.0, then apply 2.0.1 as a free maintenance update.
Unfortunately, Avid has removed the Eleven Rack Expansion Pack from their main storefront. You must locate the official legacy files:
This process takes approximately 10 minutes. Do not power off the Eleven Rack or unplug the USB cable once you start.

The Eleven Rack Expansion Pack 2.0.1 firmware update was the final and most stable release for the platform, delivering transformative new amp models and effects to a late-2000s hardware unit. However, due to Avid discontinuing the product and all driver support, performing this update today requires:

The Eleven Rack Expansion Pack (ERXP), which includes firmware version 2.0.1, is the final significant feature update for the Avid Eleven Rack.
