The Hybrid Engine. Option coming soon to HDX Systems.

The Hybrid Engine maximizes the performance of Pro Tools by using your native CPU and HDX DSP processing at the same time. When you put a track in DSP Mode, the HDX Engine accelerates real-time AAX DSP plugins while your CPU plays back the rest of your mix. And because every AAX DSP plugin has a native counterpart, you can move seamlessly between worlds—just click a button. Record with HDX DSP power for near-zero latency monitoring. And work natively with the same plugins.
