I guess it does make the point that there is a limit to practical headroom for RAM usage.  Just as they recommend that you not fill your boot drive up to 100% ...
 
Good thing RAM is relatively cheap.  But 75 instances of Kontakt ... wow! 

I know... it's a crazy number of instruments. But could it realistically happen? I don't know... seems like it's possible. This is a string orchestra piece, with 4 divisi violin and viola parts, 3 divisi cello parts, 2 bass parts, 2 solo violins, 1 solo viola and 1 solo cello. So with one instance for each, you'd be up to 17 instances. Since I don't have all the articulations I want in any single instance, I pretty much have to double that, so maybe 34 or so is what I'll end up with. But... this is just a string orchestra! Add in the rest of the orchestra, and you could get up to a pretty big number. Granted, with a bigger orchestral piece, you wouldn't be likely to need that much detail... but you might! Like I said, just experimenting right now.

I'm trying to envision a real-life scenario with 75 instances of Kontakt...can't. Even if you were building an 80-piece orchestra out of individual solo instruments, you could still manage that with only 5 instances of Kontakt.

So you'd have 16 instruments per instance. I know that can be done, but as a practical matter, how would you work on the individual parts? I don't know of a way to arrange the piano roll or (especially) the staff view in a way that would be tolerable. Could be my own ignorance... I've always avoided the multiple-instruments-per-instance approach because editing became such a pain. If there's a good way to do it, do tell!
