Custom Bank Selects
Logic Pro provides 15 bank numbers (0 to 14) for each standard instrument,
multi-instrument (including sub-channels), or mapped instrument object. You can create
custom lists, consisting of as many events (of any kind, even SysEx) as you like, for each
of these banks.
Whenever you change the bank manually, or send a standard bank change message from
Logic Pro, the entire list for that bank is transmitted to your sound module.
To set up custom bank select messages
1 Select the instrument you want to define bank select messages for.
2 Choose Options > Define Custom Bank Messages.
A window similar to the Event List opens, with a single, default bank select message for
banks 0 to 15. (The default used is a MIDI controller #0 message, with a value equal to
the bank number.)
You can create MIDI events here as you would in the Event List, by cutting, copying,
inserting, and editing. (See Editing MIDI Events in the Event List.) The only difference is
that you enter a bank number, rather than a time position.
