this said "engine" is about internal, under the hood, qtractor's engine.
whenever this message is shown, you can please carry on with normal business in qtractor: later, it will try to recover or restart itself as soon you hit any transport controls or you open a new session for that matter.
otoh. ardour does not "incorporate" jackd whatsoever. it just happens that, when jackd is not currently working, it presents you with a qjackctl-like interface for you to start it on its own. quite frankly i find this interface design as one of a typical egoistical behavior... but, nevermind, ardour's prime author is also the one who gave us jack in the first place, so let's stop whining about that kind of treat ;P
