It's the difference between line level amplitude vs instrument level that presents the problem.  

Best to either design 2 opamp buffers using a supply greater than 9V (be it single or bipolar) OR use a standard 9V opamp buffer and maybe use a dual pot to pad the input (but now the impedance becomes variable AND the tolerance of the pots can play havoc with balancing).

I have used both when I was splitting keyboards and the difference was minimal.  But if I was to do it again I'd stick with a charge pump/virtual supply
