If you have an Apogee Symphony I/O or Symphony I/O MkII (or a Rosetta/16x with X-HD card) and you’re using it in Pro Tools HD mode with an HDX card, HD Native card, or HD Native Thunderbolt and you’re not able to see HDX/HD Native as a possible selection in the Pro Tools Playback Engine, there are a few things to check:

 

  • If you’re using a Symphony I/O (mkI or mkII), confirm it is properly connected to the HD card/box and that the unit is in ‘Pro Tools HD’ mode.
  • Confirm that you have installed the ‘HD Driver’ for the version of Pro Tools you’re using (this is a separate install from the Pro Tools software). The installer is included in a separate folder in the Pro Tools installer package.
  • If you are using a current (12.6 and above) version or Pro Tools HD, you will need a ‘Digilink IO’ license to use 3rd-party hardware with your system. Click here for more information.
