Hi All, i have 40 stems and have imported them as 40 separate audio tracks on to a new Logic Pro project. I have adjusted the audio preferences for better CPU workflow and power. However the Drive I/O keeps spiking the full bar as I monitor the CPU usaged and whilst playing all the audio tracks. The processing threads remain low and fluctuate only a margin of the bar monitor. Trying to understand why the CPU overload keeps popping up constantly. Please help
