Hi, yes I had seen that and followed it fine until part 8 when it wants me to "insert the Ultranova editor plug in into a midi track" - not sure if I am missing something there? I gave created a midi track using the Ultranova at this point but don't know if I am following the instructions correctly!
Does this help? It focuses on the installation and usage of the editor plugin:
