I don't mean to double post this, but it's different problem than were it was posted....
Before (software) I could just go to: load tab > empty kit > factory kit, load whatever kit I wanted, then repeat the process when I wanted to switch kits - but now it loads two kits instead of replacing the first
Also and this is more of an observation since I downloaded the update:
I could have swore when I use to start spark, whatever kit I was using last, was still loaded, now it's always studio drums.
