Problem
Has anyone found a workable way to multitrack using HXN that doesn't hog or max out their system pretty quickly?
System
2016 32G Ram iMac 5K (10.12.6) (I use it for 4K video editing so its plenty snappy).
Scenario/Workflow
Open a new project in Logic (10.4.1) Only Logic open and running on the system.
Open once instance of superior drummer (2.x) all samples loaded in RAM/cache - 2Gb max.
Open two instances of HXN and select say PV Panama for stereo rhythm guitars (L+R)
Open
