All your listed commands are controller changes, so there is no such
danger.

Controllers 0x62/0x63/0x06 are the standard indirection scheme for
"non-registered parameters".

So we have these NRPNs:
0/0	breath gain
0/1	bite gain
0/2	bite AC gain
0/3	pitch bend gain
0/4	key delay
2/0	MIDI channel
2/1	fingering mode
2/3	Velocity
2/4	Breath CC1
2/5	Breath CC2
2/7	Bite CC1
2/8	Bite CC2
2/9	Pitchbend UP
2/10	Pitchbend DOWN
2/11	Transpose

Most sequencers allow to set these parameters directly (instead of
entering three controller change command) when given the NRPN MSB/
LSB values.
