Oh, sorry -- guess I wasn't clear.  It actually handles the NRPN message
sequence quite well.  When you start to move a knob or slider, it sends
the MSB/LSB (98/99) messages once, and then a string of CC6 messages
as the knob continues to be moved.  IF you pause, it'll start the next
string by repeating CC98/99.  What I meant was that the sequence will
only contain *either* CC6 or CC38;  it will never send both to give
a full 14-bit combination.

I assume the result of an increment/decrement message depends on the
receiving hardware.  The step value on the Axiom always seems to be '1'
(not entirely sure about that) so if it's a 14-bit value being changed
you'd have to spin the knob pretty fast to alter the higher bits.
