I was gonna use this old MacBook Pro as a backup live .
Will these specs cut it for GP If I’m using a lot of Omnisphere / Keyscape rackspaces in my setup?
Or Do i need to purchase a better MBP?
The number of rackspaces does not matter.
More important, how many active plugins are used in a rackspace.
Its about 2 - 4 Omnispheres in each rackspace (includes Keyscape in Omni browser)
Ok, could work
But you should think about Resampling.
