Apart from scrolling with keyboard keys, why do you say that Chromophone needs and update. What do you find lacking?
I haven't installed Tassman, nor the strums. I know I'm not going to use Tassmann and I'd prefer to invest time getting comfortable with my real guitars than with Strum. Despite having 2 guitars, I'm not a Guitar heavy music person.
Lounge Lizard, Chromophone, VA and String in that order I my preferences from AAS.
