            Changing Pickup Sens.
--------------------------------------------
There are eight possible settings for each
of the six strings yielding a grand total of
48 SYSEX commands. You figure it out! See
the accompanying instructions which should
make it a little easier than the crypto
formula that is listed in the manual. If you
use the GI-10 with more than one guitar in a
live performance situation, I would imagine
that this capability would be absolutely
essential!

This list should obviate the need to pull out a calculator and burn the midnight oil trying to decipher Rolands' semi-cryptic instructions for putting these commands together. For those of you who need to control the pickup sensitivity (not listed due to the shear bulk of commands), here's the skinny on how it's done. Look at any of the commands listed above. What we're dealing with is always an exact 11 bytes of information. Throw the first 5 (F0 41 10 70 12) right in the garbage. We don't need to understand them, we just need to know that they are ALWAYS the same when sending commands to the GI-10 and they need to be there (so get them back out of the garbage can.) The next three are the address bytes. Look up which string you need to change in the chart on page 20 of the manual. String #1 = 00 00 08, string #2 = 00 00 09, etc. The next byte is the data byte which contains the actual value MINUS ONE of the sensitivity setting (note that possible values are 0-7 but the GI-10 displays 1-8.) So, if you want to set string #2 to a sensitivity setting of 8, the four bytes you would use are:

               00 00 09 07
                      |  |---- Sen. setting of 8 (MINUS ONE)
                      |--------String #2

The next to the last byte is the dreaded checksum. Read the description of how to calculate this byte in the manual and then go in search of a college level quantum physics student.... OR, simply add the four bytes together into one sum (three address bytes plus the data byte) and then subtract this total from 80H. Note that all these values are in hex notation so a hex calculator is real handy. In our example above, the results would be:

               00 + 00 + 09 + 07 = 10H
               80H - 10H = 70H = checksum

The last byte (F7) is the standard 'End of Sysex' message. It's always the same... like the first five bytes, don't worry about it. Just use it.

Therefore, the complete command would be: F0 41 10 70 12 00 00 09 07 70 F7

I know that this description is longer than what it would have taken to simply list all 48 possible commands for pickup sensitivity... but you wouldn't have learned anything, and I didn't have to punch 6000 keys on my hex calculator!
