I didn't write any C++ but I looked at the C++ code and it looks
trivial to change the pitch bend messages to MTS.  What would be more
difficult is adding all the options so that either pitch bends or MTS
would work — or remembering the current state so you only need to send
a message when something changes.

I tested with FluidSynth, and there's an update that I don't think I
pushed.  I think it was that you need to use the all devices Device ID
(0x7f) instead of the channel number.
