As part of the Pro Tools | Ultimate 2021.6 software release, Avid's Hybrid Engine has been made available for HDX Systems. Combining added power for HDX Systems with on-demand access to near zero-latency recording, the Hybrid Engine intelligently splits processing between native and HDX DSP mix engines. This allows users to take advantage of their host computer’s mixing and processing power, while providing access to HDX’s DSP for supplementing computing power and recording through AAX DSP plugins with virtually no latency. As a result, massive sessions can operate more smoothly with a low CPU load, optimised voice usage and reduced system delay.
With the Hybrid Engine, a single HDX card can handle 2,048 voices at all sample rates providing plenty of headroom for all the plugins, virtual instruments, surround mixes and other elements. When tracks are put into DSP Mode, the entire signal chain and AAX DSP-compatible plugins are processed directly on the HDX card while the host computer plays back the rest of their mix. When toggled off, the track reverts to Native Mode, allowing users to easily migrate between tracking and mixing without latency issues.
