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 HD9. 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.

When an AD16x & 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 ‘192 Digital I/O – unit A’. The digital inputs of the DA and the digital outputs of the AD will both show up on ‘192 Digital I/O- unit B’. This is so the hardware inserts work correctly- analog inputs line up with analog outputs.
