• Generic Drivers. These can be used to send and receive any type of MIDI data.
• List Drivers. These do not send or receive MIDI data at all, instead they are only used to select from predefined name lists.
There are two Generic Drivers, called Any Dump and Generic. The first one is used with devices where the only way to make it give away any of its settings is by pressing buttons on the front panel. The "Generic" Driver is more advanced. With this, you can type in System Exclusive codes yourself to create a specialised driver. You can also rename the driver to that of the device you have customised it for. Generic Drivers are described in detail on page 152.
You can add the same Generic Driver to the list several times and give each "instance" of it a new name in the list (probably the name of the Device).The List Drivers (most often) contain empty cells in the Patch Manager. List drivers are used with instruments for which you either can't, or don't want to collect names via MIDI. An example of a List Driver is the General MIDI one (see Example 2, below) which contains a predefined list of all the Program names in General MIDI compatible devices. But if you yourself have another Device which is not supported otherwise, but for which you would like to select Patches by name, use one of the List Drivers.
The only difference between the different list drivers (found in the LIST directory inside the GENERIC directory in STUDIO.DRV) is how their patches are organised. For example the LIST2_64 Driver has two Banks of 64 Patches each in the Patch Manager window. This would be used for example with a Roland Juno 106 which organises its Programs in two Banks of 64.
You can add the same List Driver to the list several times and give each "instance" of it a new name in the list (probably the name of the device).
