Travel sick Tulk

Please can someone help? I am new to digital music writing & especially using vst plugins. I am getting into crescendo, but now I'd like to start expanding my cataloge of sounds, my friend has recommended Komplete Kontrol, but before I start spending, Ibsee there is a free version Komplete start. Before I download anything, will it be compatable with Crescendo? I am looking forward to getting my ideas down in the way I hear them in my head.
