Host and Arturia Collection CPU

Hi everybody! I’ve recently started to use Host with Arturia Collection 7 but I’m noticing that when you’ve, let’s say 4 or 5 Hosts placed all with Arturia VST and a couple of sequencers and reverbs, the CPU starts to suffer and the sound starts to crackle. This isn’t happening in Ableton for example, so I assume my Macbook Pro works fine there.

My MacBook Pro specs: MacBook Pro (13-inch, 2016) 2,9 GHz Intel Core i5 16 GB 2133 MHz LPDDR3 Intel Iris Graphics 550 1536 MB

Do you have any tips to reduce CPU consumption? For example, I’ve tried to reduce the Frame Rate but when opening the VST interface looks like frozen, not really helpful :cold_face:


Try with and without the “Use worker thread” option on the right-click menu of the Host modules, and also try different values for Rack’s “Engine / Threads” setting.
