Filter MIDI messages in MainStage
You can filter some MIDI messages for a channel strip in the Channel Strip Inspector. When you select one or more MIDI message types in the Filter section of the Channel Strip Inspector, the corresponding MIDI message types are filtered out of any incoming MIDI data and are not sent to the channel strip.
You can filter the following types of MIDI messages:
Pitch Bend
Channel Aftertouch
SysEx
Continuous Controller (CC) messages 0-127
Filter incoming MIDI messages
In the MainStage Channel Strip Inspector, click the MIDI Input tab.
In the Input Controller section of the MIDI Input tab, select the checkbox for the MIDI messages you want to filter.
If you have created a controller transform, you can filter the input message type, and the controller transform still sends its output message type. It is also possible to filter the output message type, but in this case the output of the controller transform is filtered. See Create controller transforms in MainStage for more information.
