To change information already available on the MAS-
TER track, proceed as follows:
(1) Use the [ß][†] buttons or the [DATA÷ENTRY] dial to
select the list entry you want to edit.
The name of the selected parameter appears in the
upper right-hand corner of the display:
(2) Press the DATA ENTRY [®] button to select the
(first) value.
(3) Modify the value:
• Rotate the [DATA÷ENTRY] dial to set the desired
value. —or—
• Set the value using the [DEC]/[INC] buttons. —or—
• Press the [DATA÷ENTRY] dial and enter the value
using the numeric pad that appears in the display.
If you choose to work with the numeric pad, proceed
as follows:
• Press [Delete] to clear the currently selected figure
(e.g. the “7” of “127”).
• Press the [+10%] or [–10%] field to increase or
decrease the current value by 10%.
• Press [ENTER] to confirm the value.
—or—
Press [CLOSE] to close the numeric pad window with-
out changing the value.
The parameters you can change are:
■Tempo Change (BPM)
(20~250) Specifies the song tempo. If necessary, you
can insert tempo changes anywhere within the song.
This could even be done in real time (using the
TEMPO REC SW parameter) so as to obtain a more
natural result. See page 157.
■Beat Change (Numerator/Denominator)
(Numerator: 1~32/Denominator: 2, 4, 8, 16) Specifies
the song’s time signature. If necessary, you can insert
tempo changes anywhere within the song. After
pressing [®] for the first time, you can specify the
numerator (the number of beats per bar). Press it
again to specify the denominator (the note value of
each beat).
■SysEx
After selecting a “SysEx” line and pressing [®], the dis-
play looks more or less as follows:
On this page, you can edit an existing SysEx string.
Use the [√][®] fields to select a byte (a pair of num-
bers) in the current line, and [ß][†] to change lines.
“SysEx” refers to system-exclusive messages only the
G-70 (or another GS-compatible sound source)
understands. Changing these values requires a thor-
ough understanding of the purpose and structure of
SysEx messages – and that lies beyond the scope of
this manual.
Here are some guidelines, however:
• SysEx messages are usually found in the fine print of
an owner’s manual. If not, the manufacturer (or
dealer) can supply a copy of that information.
• SysEx messages need to be entered in hexadecimal
format – hence the [A]~[F] fields that are considered
numbers. (“Hexadecimal” means that each group
contains 16 different numbers rather than 10.)
“41” in hexadecimal notation actually represents the
number “66” in decimal notation [(4 x 16) + (2 x 1)].
• SysEx messages always start with “F0” (to signal the
beginning of such a message), and end with “F7” (end
of exclusive message).
• Some manufacturers (like Roland) use a figure that
allows the user to check whether the SysEx message
is correct. That number is called the “checksum”. If
you don’t know how to calculate it, press the
[AUTO¥SUM] button icon to have the G-70 insert it
for you.
