One month after the arrival of its HDX hardware card, Avid has released an update to Pro Tools HD, now at version 10.1, that supports the card. The HDX processor offers a 5x boost in processing and adds support for 64 I/O channels by moving to a floating-point architecture. The update is only available for those who own the HDX hardware or those who do a hardware exchange from the previous HD card. Various plug-in updates are also available.
