well for me a 14-bit number with a range of 16383 is zero based, otherwise I would need an additional bit for the sign. 

also nobend=2000H indicates  a value from 0 to 16383...

The specs don't say much about how to interpret the value actually

"Pitch Bend Change.
status: 1110nnnn
data: 0lllllll 0mmmmmmm

This message is sent to indicate a change in the pitch bender (wheel or lever, typically). The pitch bender is measured by a fourteen bit value. Center (no pitch change) is 2000H. Sensitivity is a function of the transmitter. (llllll) are the least significant 7 bits. (mmmmmm) are the most significant 7 bits."
