List Drivers are simply name lists. They do not make use of the Data Dump Window at all. Instead they contain (possibly) named cells used to send out Program Change messages to a device. Use this with devices in which you never change the Patches (maybe because you can't?), but for which you would still like to select Patches from the Patch Manager.
The List Drivers are in the LISTS directory inside the GENERIC directory among your device directories. There are a number of Lists, and their names correspond to how the device organises its Patches, in four banks of 32 Patches (LIST4_32) one bank of 100 (LIST_100), etc.
There are not many settings to be made for a List Driver in Setup. But please note that you can set the number of "Child MIDI Channels" for the device if it is multitimbral. It will then have as many Child Instruments as you define here.
When you access this driver via the Patch Manager, you will see a number of empty cells. Type in the names of the Patches in the device. Use Save/Update Names on the pop-up Functions menu, and select the Update option. This will store the names in the actual driver file.
When you click on one cell, the corresponding Program Change message is sent out. List Drivers do not support Bank Select.The driver for General MIDI and GS devices is a list driver. But in this, the names can't be changed. However, it supports the "multiple Child MIDI Channels" option so that you can use it to access Patches on all 16 MIDI Channels of a General MIDI/ GS instrument.
In the Patch window, the Patches for the General MIDI driver are organised into Banks, corresponding to the instrument groups defined in General MIDI.
When you have the General MIDI driver assigned, the Instrument transmitting on MIDI Channel 10 will be labelled "Drums".
