Saving Your Custom Presets to the Macintosh
So you’ve created some great tones with your G-DEC, saved them to your own presets, and you want to
back them up or maybe share them with a friend. Well, to do this, we will
dump a preset to the Macintosh
from the G-DEC and all of the preset parameters will be stored in a SysEx file. SysEx stands for System
Exclusive and is another file format used with the MIDI protocol that is device specific. A G-DEC SysEx
file will only work with another G-DEC.
So, in order to receive the preset information in SysEx format onto the Macintosh, we need an application.
For this purpose, we will use a freeware application called “SysEx Librarian” available for free download
at
http://www.snoize.com/SysExLibrarian/ . Download the application and double click on the
SysExLibrarian icon.
For demonstration purposes, we will continue to assume use of the M-Audio UNO 1x1 USB-MIDI
converter and will assume that the drivers are properly installed. The first thing to do once the application
appears is to select “Port 1” from the pull-down menu next to the “Play” icon (see figure 7). This selects the
UNO as the device to which we will send and receive SysEx data.
Figure 7: Setting up SysEx Librarian for an external MIDI device.
The next step is to set the application into Record mode. Because the G-DEC uses three separate SysEx
messages (a header, the body, and a footer) to transfer preset data, click on the “Record Many” icon in the
upper right of the application window. You should now see a temporary window show up telling you that
the application is waiting for SysEx messages as shown in figure 8.
Now we go to the G-DEC which should be properly connected to the UNO via standard MIDI cables. To
dump one preset, select the preset you would like to store on the Macintosh using the large data wheel.
Then press the Utility button three times until the “DUMP PRST” menu item is highlighted. Then press the
Save button to dump the preset. The SysEx Librarian application should immediately respond and after the
preset is dumped should show that three messages have been received for a total of 62 bytes (see figure 9).
If less bytes have been received then the preset was not properly dumped. Try again.
