Excessive consumption of RAM when playing more complex patches

[z1reticuli]

I am running MacBook Pro, 2.3 GHZ i5, Mac OS 10.9.5, DAW at 128 samples, quality 96kHz samples, and when running Arturia Prophet, or Analog Lab and e.g. when I use Unison on a patch of Prophet, I suddenly see CPU at 82%!! And of course crackling is introduced.
I try not to run other programs when working with music. Anyone with similar experience, or a WORKAROUND?

Hi z1reticuli,
What is the preset you're using ?
How many voices of poly are you using ?
If you want to reduce CPU consumption try to lower the number of voices in the toolbar.
