Yeah that will take longer for sure, whilst I do sometimes record a live part it's 90% in the box and I've been doing it long enough to know what my go to instrument plugins are and also my mix template is all set up and ready to go so that saves a lot of time.
I also master within the DAW session instead of doing it separately - that saves tons of time when making deliverables for libraries and was taught to me by one of the Taxi members that does music full time.
