MIDI Input Filter
Use the MIDI Input Filter to prevent certain types of MIDI messages from being recorded. The MIDI Input Filter can be set to record All messages, Only the specified messages, or All Except the specified messages.
For example, to filter out program changes:
1 Choose Setup > MIDI > Input Filter.
2 In the MIDI Input Filter dialog, select the All Except option.
3 Select the option for Program Changes. Leave all other messages deselected.
 
4 Click OK.
When using the All Except option, the selected types of MIDI messages are not recorded. Conversely, when using the Only option, only the selected types of MIDI messages are recorded.
