      Differences in X-HD firmware versions

      This post explains the differences in X-HD firmware versions and how the Apogee interfaces show up in different versions of Pro Tools, depending on the X-HD version.

      X-HD version 3.0:

      Download version 3.0 here.

      All Apogee devices show up as digital Avid HD I/Os.

      HD I/O's are not compatible with any version of ProTools prior to v8.1.1. We recommended using this X-HD firmware to users of HD-Native and HDX.

      When an AD16x & a DA16x are daisy-chained in that order in Advanced Routing, the analog inputs of the AD and the analog outputs of the DA will both show up on 'HD I/O- unit A'. The digital inputs of the DA and the digital outputs of the AD will both show up on 'HD I/O- unit B'. This is so the hardware inserts work correctly- analog inputs line up with analog outputs.

      The X-HD user's guide on our website is current to version 2.07, but can be applied to version 3.0 if you replace "192 Digital I/O" with "HD I/O" and shows you all the different configurations and where the channels show up: X-HD user's guide

      • Known issue with version 3.0 firmware: There is a known issue when using 2 or more units per port (and especially when the AD/DAs are in 'Advanced Routing') where the input/output channels can become misaligned and/or mirrored. Toggling the sample-rate in ProTools will usually get the units out of this state.

      X-HD version 2.07

      All Apogee devices show up as 192 Digital I/O.

      Note: Digidesign Digi192 units are not recommended for use with ProTools HD-Native, HDX, and software version HD 11 and up.

      X-HD version 1.05

      All Apogee devices show up as regular 192 I/O's.

      Note: Digidesign 192's are not recommended for use with ProTools HD-Native, HDX, and any version of Pro Tools HD software from version 9 and up.
