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.
______________________________________________________________
ddd = 000 = set system parameters
[ 7] 0000nnnn - where nnnn = the new MIDI channel
[ 8] 0000AB65 - 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.
[ 9] F7h - end of exclusive
______________________________________________________________
ddd = 001 = set output relays
[ 7] 00004321 - where 4321 = out #4, 3, 2, & 1
[ 8] 0000AB65 - where AB65= amp. # A & B, out #6 & 5
Note that all bits are active high.
[ 9] F7h - end of exclusive
______________________________________________________________
ddd = 010 = information request
[ 7] 000000bb - where bb = memory area
valid = 00 = patch data 01-64
01 = patch data 65-128
02 = controller assignment & system set-up
[ 8] F7h - end of exclusive
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.
