Changing Reference 4 from Phase Linear to Low Latency makes no change.ĥ/ Change the plugin from DSP to Native.
Add a few tracks or plugins and you cannot work, whatever the buffer settings. BOOM CPU goes crazy, 100% usage with one single native plugin on the most powerful Apple model. You should notice no change at all (8% cpu)Ĥ/ Move that plugin ABOVE Reference 4. On my computer, it shows around 8% on the global meter (the topmost one)ģ/ Add a DSP plugin AFTER Reference 4. Here is a way that, I hope, will allow to reproduce the problem :ġ/ Create a 96KHz Pro Tools session with one single stereo track and import some audio (or not).Ģ/ Add reference 4 to a plugin slot leaving room above and below for testing Please note that my Mac is a 12 core Mac Pro, almost the most powerful one can get from Apple. The mixing necessarily happens in DSP domain.
This is not happening at lower sampling rates (44.1/48 - didn't try at 88).Īs a HDX user, I use both native and dsp plugins. I have noticed the strangest behavior when working at 96KHz with Pro Tools HDX. I just sent the following message to support, but thought it might be useful to check if some of you share this problem.
