nrpn 38xxh = 7Fh: midi channel xxh is auxiliary output
Midi message:
control 99 = 56 (38h)
control 98 = xx:
xx = 0 select midi channel 0
xx = 1 selects midi channel 1
…
xx = 15 selects midi channel 15
control 6 = 0 (master) or 127 (auxiliary)
Midi message code (in hexadecimal):
B0h 63h 38h, B0h 62h xxh, B0h 06h vv
Default value = 0 (master)
Note
Nrpn 3820h assigns all midi channels of first port (midi channels 0 to Fh).
Nrpn 3821h assigns all midi channels of second port (midi channels 10h to 1Fh)
nrpn 3820h(3821h) = 0h: all midi channels of first (second) port are master outputs
nrpn 3820h(3821h) = 07Fh: all midi channels of first (second) port are auxiliary outputs
Midi message:
control 99 = 56 (38h), control 98 = 32 (33) (20h,21h), control 6 = vv (0 or 127)
Midi message code (in hexadecimal):
B0h 63h 38h, B0h 62h 20h (21h), B0h 06h vv

nrpn 3828h = reverb master output volume
Midi message:
control 99 = 56 (38h), control 98 = 40 (28h), control 6 = vv
Midi message code (in hexadecimal):
B0h 63h 38h, B0h 62h 28h, B0h 06h vv
