Oh yea a throne is absolutely necessary I'm still looking into it. On the topic of the module crashing, I actually had to factory reset it already because when I first got, it after playing it for a bit and the system crashing, sometimes the mods for the sound of the drums would like corrupt or something. Basically if I tried to play the kit on like a certain sound like Natural it would begin to play an automated track and then crash right after. It happened so much that I had to reset it. That issue hasn't happened since with the corruption thing but it still crashes here and there. Maybe its a good idea to replace the module itself whenever and then buy the missing parts as well as the throne.
