GS-2/8 System Exclusive Information
The first five bytes are always the same for all data types;
[ 1]
F0h
- Sysex command
[ 2]
00h
- Company identity first byte
[ 3]
20h
- Company identity second byte
[ 4]
13h
- Company identity third byte
[ 5]
11h
- Product code
[ 6]
0dddnnnn
- where nnn = MIDI channel & ddd = data type
if ddd = 000 = set system parameters
if ddd = 001 = set output relays
if ddd = 010 = information request
if ddd = 011 = memory request
if ddd = 100 = switch `Thru` to `Thru`
if ddd = 101 = switch `Thru` to `Out`
if ddd = 110 = direct system control
Note that the unit must be set to channel nnnn for any ddd to have effect.

- where 5 & 6 = set out #5 & 6 to `AMP`
where A & B = set amp. #A & B to `MOM`
Note that all bits are active high.

Note that the GS-8 saves the area requested via the MIDI Thru socket. The Thru socket must be
switched to `Out` (ddd=101) prior to any information request or this command is ignored.
