Hello Dan,
I just wanted to convert my custom styles which I still use from i3 korg to Ketron sd1.
And also at the moment the sd1 style sequencer doesn't allow you to do measure erase, measure copy, measure delete, or even change the number of bars or time signiture after you set them in the beginning when you start a new style. You can only set the time signature and number of bars once. I think you should be able to change it at any point and shouldn't be stuck with it for all parts of your style.
All these limitations right now makes it very time consuming for me to make own styles on this keyboard and that's why I need a style software.
