I also have a 10 String with a baritone melody tuning. As Harald said, there are several tunings available. Depends on, what you want to do. If you want to just go for extended bass playing, then the Double Bass Reciprocal tuning would be the best.
I do also have a NS Stick, a combination of a bass and a guitar and a Chapman Stick. You can tap on it but you can also play conventional on it.
