Yes it is very cool. I thought it was great when Yamaha gave the Sequential name back to Dave Smith.
Although, I don't understand how Yamaha wound up with the name in the first place? I don't even recall a Yamaha Product the used the Sequential name? Of course I was still pretty young when this all happened.
It is also nice that Tom Oberheim was able to release new SEM Modules and a New Two Voice synth, and from what I have seen, the Two Voice was more of the Type of synth that he wanted to make.
