General Notes;
A, Following an information request (ddd = 010) and assuming the MIDI Thru socket is switched as
an Out (ddd = 101), the GS-8 will save the memory area specified, formatted as per a dump (ddd =
011).
B, The CRC is calculated from the `number of bytes` byte [8], onwards. Since both of the patch
memory areas are of the same length, it is possible to modify where the patch data is loaded by
changing byte [7]. I.e. you can load the high patches to the lower memory area or vice versa. If [7]
= 00 load = low area, if [7] = 01 = high area.
The system data is of a different length and will only load as stored.
C, Patch data is loaded/saved to/from EEPROM only. To access a new patch you must change it.
System data (controller assignments, MIDI channel, and MOM/AMP status) are all updated on
completion of a successful load operation.
System Exclusive Dumping
Sysex MIDI data dumps can be controlled from the front panel.
First, make sure any patch or system changes have been stored by pressing and holding
`PATCH/CHAN` button till `St` is displayed.
Now, when you press and hold the `PATCH/CHAN` button, `Sd` is displayed, (Sysex dump).
Note; you must continue to hold down the `PATCH/CHAN` button whilst performing the following
two functions:-
To send bytes 1-64, press `-` button. `SL` will be displayed to indicate the first lower 64 bytes have
been dumped.
To send the remaining bytes 65-128, press the `+` button. `Su` will be displayed to indicate the
upper 64 bytes have been dumped,
Note; when dumping Sysex from the front panel, the Thru socket is automatically switch to an Out,
then back to a Thru after the data has been sent.
Note 2; it advisable not to send the GS-8 any MIDI data whilst performing a Sysex dump from the
front panel, better still, disconnect the cable plugged to the MIDI In socket.
