A new CC7 message will be added to the top of the list. Click Create and then click Controller to add a controller event.This event list is similar to the normal MIDI edit event list, with one difference: Under the Position column is a bank number instead of the usual timeline position. A Bank Select Event List will open, with an MSB message for 16 banks already defined.From the local Options menu, choose Define Custom Bank Messages.In the Environment, select the Multi-Instrument for the synthesizer for which you would like to define custom bank messages.To configure Logic to send custom bank messages: Consult the MIDI implementation chart for your synthesizer to determine the particular combination it requires for bank changes. MSB and LSB stand for 'most significant byte' and 'least significant byte,' respectively. Most synthesizers use a combination of Control 0 (Bank MSB) and Control 32 (Bank LSB) events to trigger bank changes. Logic offers several preset bank select message formats, but in some cases you will need to define a custom message format to change banks on a particular synthesizer.
