I don’t use key switches all that often and not sure how Live Synch might change things, but as I remember (and just tested in and out of Live Synch) the green Key Switch keys are shown in pad view only.
When you switch to Main, they disappear. Also, If you lasso the pattern buttons (in Pad and Main views), you will bind all the patterns and you won’t see the green keys in Pad view.
Maybe there is a setting that changes this behavior but I can’t find it.
Speaking of key switches, not exactly sure what it would look like, but now with MVO I’m using articulations more than ever. I would love to see some key switching wizardry show up in Scaler. I"m sure there are some creative approaches, just have not found them yet.
