The Studio Module usually selects Patches in your devices via Program Change. However, that’s not good enough if the device has more than 128 Patches. If it does, some combination of messages is used, for example Bank Select plus Program Change or a combination of two Program Change messages, or even System Exclusive. Regardless, the Studio Module will always allow you to select directly between all the Patches in your device. It even tells you at the top of the window, in a box and beside it, which Patch is selected, and how it was done.
If this line says simply "PROG" followed by a number, only one Program Change was used. If it says BANK # / PROG #, a combination of Bank Select and Program Change was used. If it says SYSEX, System Exclusive messages were used to select the Patch. In some cases for example two Program Change messages were needed, in which cases it says PROG # / PROG #.
P Make sure to turn off Program Change tables in your devices, as described in the check list on page 79.
