The least of my worries is waiting for plugins to load, because I’m usually getting the system started up before I’m ready to get busy, for some of my projects take good time to get thru the samples (Trilian, String Machine)
But man I can relate to the intrusion of technical faults (whatever they might be or by whomever’s causing) that just get in the way of trying to quickoly express an artistic or musical (however you look at it) idea.
When I start getting a muse, I speed up, and I want to go fast, I need to be at the speed of my brain as it has a limited window for expressing a sudden gush of inspiration. This is the out-of body experience that I love, it is the resaon why I do it.
So while I may disagree with the OP, but for the way he frames his topic, sans using “Cubase”, the overall message is that we don not really want anything to intrude or interrupt the process. That is very important to me. I don’t get multiple chances and infinite time to get it out, and the second time around is often compromised, as you’ve just moved on to a whole 'nother section of the brain then, trying to replicate an original thought.
