Konkreet Labs have put together a tiny tutorial for setting up Konkreet Performer to send notes to Dron-e. Since Konkreet Performer is sending OSC, you need to add this Konkreet Translator to the Reaktor ensemble to get MIDI notes out of it. This means you won't be able to make use of this with the free Reaktor Player, since you will need to be able to modify ensembles. Then again, you couldn't even run Dron-e unless you have the full version of Reaktor ($400) anyhow, because it is a user-made ensemble.
For those of you wondering if Konkreet Performer is worth grabbing while it is on sale, I think this will answer your question for you in 40 seconds. If you have the stomach for this kind of nerding-out, you can make interesting things happen, but only if you put in the time to make custom OSC connections/MIDI translations! It can be used to send OSC to anything that will accept it, but for the most part that just means Reaktor. On the other hand; if you've ever wanted a Modular Synth, what you really want instead is Reaktor!
