I've been thinking of an adapter to convert up to 3 pedals into one fake "triple pedal" using this simple circuit (thanks to all happy owners of a NTP for your information, Patshi and bertpeeters). This will not make any half-pedaling, unless you use a special pedal for sustain, but at least should allow you to use the una corda function with an ordinary pedal, which is not possible currently on a NS2 or NP.

You will need:
1 TRS stereo plug
3 mono jacks
1 resistor 10K
1 resistor 5.6K
some cable (does not need to be audio cable, or shielded, any cable should work).
You can solder the resistors inside the jacks with care of not doing any short circuit.
Then you can plug any type of pedal or switch to the jacks.
I have not build it yet, but if anybody does let me know if it works
