Yes it wasn't able to recall settings when a preset was selected. The controls didn't move. (Initially I thought it was just that the graphics weren't updating to show the controls in their updated positions, but I was mistaken.)
I see you changed the harmonic structure somewhat.
I've been testing it with frequency spectrum analysis, with test signals run into it. (And also listening to it on musical material). It sounds relatively the same as before but I can see some differences in the harmonic overtones.
You're doing a great job!
