MIDI message code (in hexadecimal): B0h 63h 37h, B0h 62h 55h, B0h 06h vv
OM: If 0, spatial effects ON. Spatial effects parameters can be controlled using NRPN
3720h (volume), 372Ch (delay time), 372Dh (stereo/mono) and 372Eh (2/4 speaker
mode) (see Section 1.3).
If 1, 3DMIDI™mode, four-speaker MIDI output. Each MIDI channel can be output to
front or rear speakers using NRPN 3800h to 380Fh, reverb and chorus can also be
routed.
 NRPN 38xxh = 0h: MIDI channel xxh is front speaker output
 NRPN 38xxh = 7Fh: MIDI channel xxh is rear speaker output
 NRPN 3810h assign all MIDI channels to front or rear speakers:
- NRPN 3810h = 0h: all MIDI channels are front speaker output
- NRPN 3810h = 07Fh: all MIDI channels are rear speaker output
 NRPN 3820h and 3821h control reverb output volume :
- NRPN 3820h = 0h to 7Fh: reverb front speaker volume (Default value = 07Fh)
- NRPN 3821h = 0h to 7Fh: reverb rear speaker volume (Default value = 0h)
 NRPN 3830h and 3831h control chorus output volume :
- NRPN 3830h = 0h to 7Fh: chorus front speakers volume (Default value = 07Fh)
- NRPN 3831h = 0h to 7Fh: chorus rear speakers volume (Default value = 0h)
Default power-on value: OM = 0 (Spatial effects ON)
