It’s still fairly safe to bounce midi from a current project, import the midi into a new project, route it to HSO, bounce the audio back into “current” project. It’s safer to do it one or two channels at a time. Whenever you need to adjust lines, adjust the midi, throw it back into that HSO project and rebounce when needed.
Feels pretty safe, and I can still get all the sweet HSO goodness without forcing it to work bridge too much. Funny, the instruments need to be “dirtied” back down, they are that pristine.
At least it’s ok while I’m still on C5 on OS 10.68.
